Abstract- Heavy adoption of alternative power
supplies and e - mobility produces power imbalances and
overload in the current power grid, posing considerable
management and operational challenges. Considering
massive initiatives by electric companies, authorities,
and scientists, smart grids are still in their infancy in
terms of addressing those concerns. The purpose is to
increase a basic layout that can maintain grid stability
while maintaining a requisite quality of services, as well
as to advance the growth of a generic approach for
monitoring the attributes of such stations regarding
traffic character traits, grid storage size, and cost
structure, and main financing. The primary optimization
approaches used in a variable pricing context to attain
goals like energy losses and electric costs mitigation,
peak demand reductions, voltage control, distributing
network overload reductions, and so on are covered in
this study.

1. INTRODUCTION
In past years, rising environmental consciousness has fueled
the quick adoption of sustainable technological advancements
like alternative power supplies and EVs in current PS to
minimize global carbon emissions. This situation results in
system-level power imbalances as well as localized delays in
DS, posing serious issues for conventional grid planning and
management. Some of the major aspects covered in this study
are flexible electrical tariff regulations are critical in the
energy market for affecting consumer electric use. We looked
at a variety of cost rules from the standpoint of EV recharging
to see how they affect EV charging behavior. This study also
includes the optimization goals achieved throughout the
charging scheduling phase.
EVs obtain electricity from the system by connecting to a
charging point. The charged battery stores power and has been
utilized to activate the motors that turn the tires. Electric
automobiles travel faster than cars with traditional gasoline
engines, helping them feel lighter to drive.
An SG is an electrical platform that facilitates digital
technology to facilitate a two-way flow of electricity and
information, as well as the identification, response, and
avoidance of changes in usage and other problems. The 6
major SG targets are smart meter design, load shifting, electric
automobiles, wide-area spatial consciousness, scattered
energy supplies and storing, and distributed administrations.
After examining all of the previous studies stated in this
research, we can infer that using EVs in the smart grid can
assist to increase system dependability by decreasing losses,
increasing losses, and enhancing smart grid load capability
features.
An SG test platform is essential in this aspect for developing,
analyzing, and demonstrating different unique SG approaches,
including demand reaction (DR), real-time price, and
congestion control [1]. The primary aim of the research is on
optimizing EV recharging schedules under dynamic power
billing systems such as Real-Time Pricing (RTP), Time of Use
(ToU), Critical Peak Pricing (CPP), and Prime Times Refunds
(PTR). Each payment scheme has been explored in detail, with
key features highlighted [2]. A probabilistic framework was
developed to evaluate the CS results in terms of traffic
patterns, power storage capacity, prices, and main financing
[3]. This study discusses the approach used for energy flow
under the V2G concept, including the GA and PSO [4]. This
study gives a comprehensive fundamental evaluation of the
operation of several programs used inside the power
management system, such as consumption response, demand
management, and energy quality assurance [5]. This study
proposes coordinating the management of EVs, wind farms,
and PV power in a microgrid for microgrid frequency
command [6]. This research will look into and evaluate the
obstacles that electrical systems face when it comes to
improving PQ [7]. This work proposes a
battery/supercapacitor (SC)-powered EV switched-reluctance

motor (SRM) operation with grid-to-vehicle (G2V) and
vehicle-to-home (V2H)/V2G features [8]. Using a simulated
SOC prototype and synchronized operation of power flows
amongst some of the hands of the same kind of distinct phase-
units by taking full benefit of circulation current, this article
presents a multi-energy management approach for a modular
multilevel converter (MMC) centered EV facility to be
incorporated into the SG [9]. Throughout this study, we offer
a two-tier energy management scheme (EMS) with a Superior
Command Center at the top and an EV command center at the
bottom [10]. We describe a methodology related to software-
defined networks (SDN) and blockchain (BC) to handle two
difficult concerns in EV-assisted SG ecologies: confidentiality
and energy safety [11]. The real-time V2G control scheme
under price volatility is investigated in this research, where the
power price is adjusted periodically per hour. The DQN
technique, which mixes popular Q-learning with such a neural
network, influenced our approach [12]. This article presents a
day-ahead marketplace paradigm for smart DS congestion
control [13]. To reduce the total daily expense suffered by CS
operators, an intelligent charging scheduling algorithm
(ICSA) with the incorporation of henry gas solubility
optimization is presented [14]. This article evaluates the latest
research on dispersed recharging control techniques, in which
calculations are spread over numerous EVs and/or aggregates
[15]. This study presents AEBIS, an AI-enabled, blockchain-
based EV integrating solution for SG power administration
[16]. Utilizing the differential evolution (DE) optimization
algorithm, this study presents an IoT-based centralized control
scheme for coordinating EV and DES deployment [17]. The
research reveals that regulated recharging and adaptable
production of hydrogen infrastructures can help to minimize
peak load spikes and minimize renewable electricity
attenuation, lowering the operation of the system, generation,
and network expenditures [18]. This work presents a two-stage
optimization to analyze the effect of distribution feeder
reconfiguration (DFR) with various EV scheduling strategies
on the DS in terms of inefficiencies and voltages [19].
Regulations and operating architecture for a G2V-based plug-
in electric vehicle (PEV) aggregators have been developed
[20]. The imperialist competitive algorithm (ICA) and the bat-
inspired algorithm (BIA) were employed as optimization
strategies in this study to tune the model predictive control
(MPC) controllers with PHEV for LFC in the SG system with
RES adoption [21]. This research discusses a novel use of EVs
to swiftly assist reheated thermal turbine units in stabilizing
while load needs vary [22]. The topic of energy trading
network topology control (ENTRANT) for PHEVs is
investigated as a multi-leader multi-follower Stackelberg
game in this research [23]. An upgraded publicly accessible
FCEV supplied 9.5 kW of AC electricity to the network in a
sequence of V2G testing [24]. The FFA-GBDT method
presented for the energy management system (EMS) among
EVs and DS in this publication is a hybrid approach that
combines the implementation of the Fertile Field algorithm
(FFA) and Gradient Boost decision tree (GBDT) [25]. This
research proposes a real-time multilayer energy management
method (RMEMS) for EV recharging. The centralized
repository is a tri-level optimization model (TOM) [26]. Using
a multi-objective multiverse optimization method (MOMVO),
this research presents a charging/discharging technique to
improve the usability of EVs on a controlled timetable by
taking into account optimal operating behavior [27]. This
study looks into the effects of a V2G enabled bilateral off-
board EV battery charger on grid current harmonic
compensation (GCHC) and reactive power compensation
(RPC), as well as how it can be used as both a rechargeable
battery and a generator [28]. An integrative period of use
price-based demand response (TOUPBDR) and dynamic G2V
charge routing of EVA are modeled in this work to optimize
regulating functions and charging costs at the same time [29].
The existing research developments and upcoming projects for
power electronics-based systems that allow the combination of
PV sources of energy and the SG with CS for EVs and PHEVs
are reviewed in this article [30].

3. CONCLUSION AND FUTURE SCOPE
In this paper, a study has been done about the coordinated
control of Electric vehicles in super-smart grids. Various
techniques have been proposed in this literature such as
residue-based methods, Heterogeneous Ethernet-based mesh
networks, liner, and non-linear optimization programming
algorithms, genetic algorithms (GA), artificial neural networks
(ANN) based algorithms, swarm optimization (PSO)
techniques, fuzzy logic-based approach, adaptive neuro-fuzzy
inference system (ANIS) techniques, 2D searching method,
and model predictive control.
A state-of-the-art review of the current optimization methods
for synchronized control of EVs in super-smart power grid
networks was conducted in this article. Several points will be
examined, including optimum charging-discharging of EVs,
optimized coordination of EVs, power control of EVs with the
SG, losses minimizing of EVs with smart grid cooperation,
and energy performance improvement solutions for EVs with
smart grid synchronization. The following are a few of the
conclusions:
It is proved that the proposed centralized and
decentralized control solution for EV charging addresses
charging costs, network problems, and local voltages at
the same time.
Administering supplementary services and maximizing
income through dispersed charge control methods.
When all of the costing methods are compared in terms of
economics, equality, and hazard motivation, RTP
emerges as the clear winner.
Promotes operating effectiveness at higher velocities
while also improving frequency regulation ability.
Across all EV planning solutions, DFR results in
substantial reductions in system losses and minimum
voltage levels.
Considering the price, operation time, precision, durability,
and velocity of numerous optimization methods, some
limitations can be solved by applying new natural-based
optimization methods. The following are a few of the potential
scopes of this review article:
In the future, RMEMS for EV charging in the domestic
and urban areas of additional countries will be tried.
How the design of the energy trade route may be regulated
in advance depending on the predicted PHEV trend.
To incorporate EVs more securely, a cost-effective
separated DC converter is worth researching.
Examine the communications infrastructure for high
traffic loads and faulty communications networks.

Electric vehicles were introduced to the market as a way to reduce dependency on internal combustion engine-driven transportation systems. However, this method increased the burden on the current electrical grid rather than reducing it. In the power grid, distributed generation ideas are presented to reduce this burden. In order to reduce the distribution systems' overall real power loss, this research demonstrates how hybrid optimization algorithms, including genetic algorithms and Monte Carlo simulation methodologies, can be used to determine the best location and size for various types of distributed generation with electric vehicle scheduling. The suggested approach's practicality was tested using a 16-bus distribution test system. At both static and ZIP load models, the more effective kinds of distributed generation with electric vehicle couples are DG2 with fuel cell electric vehicles.

This study addresses the issue of diagnosing faults in electric vehicle motors and presents a method utilizing Improved Wavelet Packet Decomposition (IWPD) combined with particle swarm optimization (PSO). Initially, the analysis focuses on common demagnetization faults, inter turn short circuit faults, and eccentricity faults of permanent magnet synchronous motors. The proposed approach involves the application of IWPD for extracting signal feature vectors, incorporating the energy spectrum scale, and extracting the feature vectors of the signal using the energy spectrum scale. Subsequently, a binary particle swarm optimization algorithm is employed to formulate strategies for updating particle velocity and position. Further optimization of the binary particle swarm algorithm using chaos theory and the simulated annealing algorithm results in the development of a motor fault diagnosis model based on the enhanced particle swarm optimization algorithm. The results demonstrate that the chaotic simulated annealing algorithm achieves the highest accuracy and recall rates, at 0.96 and 0.92, respectively. The model exhibits the highest fault accuracy rates on both the test and training sets, exceeding 98.2%, with a minimal loss function of 0.0035. Following extraction of fault signal feature vectors, the optimal fitness reaches 97.4%. In summary, the model constructed in this study demonstrates effective application in detecting faults in electric vehicle motors, holding significant implications for the advancement of the electric vehicle industry.

Transports is one of the sectors that produce the highest emissions of CO $_2 $ ; in the last ten years, there has been a process of decarbonization which has led to a considerable increase in Electric Vehicles (EVs). However, the sudden introduction of a large number of Electric vehicle supply equipment (EVSE) supplying electrical energy to EVs could cause problems in the management of the electric grid which must cope with the consequent increase in the electrical load demand. In this context, the 24 hour ahead forecast of the power curve associated with the recharge of EVs becomes of vital importance to ensure the reliability of the electric grid.

A three-phase four-leg bidirectional power converter used as an input stage of an energy storage system using the inductance (L), capacitance (C), and inductance (L) or LCL filter on the grid side is considered. The article provides a variant of the three-phase four-leg bidirectional converter control system implementation based on 3D space vector pulse-width modulation and per-phase voltage control. A brief analysis of the applied control algorithms of the three-phase four-leg bidirectional converter in inverter and rectifier modes is given. A computer model has been built to investigate the operating modes of the converters of the designated class with both balanced and unbalanced load. Studies were carried out by computer modeling methods in order to optimize the parameters of the LCL filter on the grid side with bidirectional energy exchange. Optimal LCL filter parameters and modulation frequencies are determined for the developed converter, providing acceptable quality indicators when operating in bidirectional mode.

Rapid growth in the number of electric vehicles (EVs) calls for research on traffic equilibrium in urban transportation networks (UTNs). As a result of the interaction of EVs and fast charging stations (FCSs), traffic flow is influenced by EV drivers’ charging preferences. However, little research investigates the impact of heterogeneous charging preferences across EV drivers on the traffic flow at traffic equilibrium. This paper establishes a traffic model where the heterogeneity across EV drivers is reflected in the monetary value of time and sensitivity to electricity prices. Based on the traffic model, we propose a Stackelberg game to model the interaction of EVs and FCSs while ensuring the user equilibrium of UTN. The game features a hierarchical structure. At the higher level, FCSs play a non-cooperative game by strategically setting electricity prices with imperfect information of other FCSs. At the lower level, EVs play an evolutionary game to charge at FCSs with the lowest cost. An adaptive step control method is designed to prevent potential oscillations near the Nash equilibrium. Numerical results show that the difference in EV flow on the road can reach 18.42% without considering heterogeneity and considering heterogeneity. The proposed framework can illustrate how the heterogeneity across EVs influences the formation of traffic flow in traffic equilibrium calculation.

Recent year has brought considerable advancements in Electric Vehicles (EVs) and associated infrastructures/communications. Intrusion Detection Systems (IDS) are widely deployed for anomaly detection in such critical infrastructures. This paper presents an Interpretable Anomaly Detection System (RX-ADS) for intrusion detection in CAN protocol communication in EVs. Contributions include: 1) Feature Extractor; 2) Anomaly Detection System; and 3) Explanation Generator for detected anomalies. The presented approach was tested on two benchmark CAN datasets: OTIDS and Car Hacking. The anomaly detection performance of RX-ADS was compared against the state-of-the-art approaches on these datasets: HIDS and GIDS. The RX-ADS approach showed comparable performance to the HIDS approach on OTIDS dataset and outperformed HIDS and GIDS approaches on Car Hacking dataset. Further, the proposed approach was able to generate explanations for detected abnormal behaviors arising from various intrusions. These explanations were later validated by information used by domain experts to detect anomalies. Other advantages of RX-ADS include: 1) the method can be trained on unlabeled data; 2) explanations help experts in understanding anomalies and root course analysis, and also help with AI model debugging and diagnostics, ultimately improving user trust in AI systems.

A dual mode traction power supply system (TPSS), as a high-efficiency transportation approach, is composed of a mainline railway (AC traction power supply system) and an urban railway (DC traction power supply system). However, due to the neutral sections, the power from the two systems has been isolated, resulting in a low utilization rate of regenerative braking energy (RBE). The power flow from the two systems can not be managed cooperatively, causing high electricity bills. Therefore, this paper proposes a dual mode based energy router (DMER), which provides a path for energy interaction between two systems through multi-terminal converters. The proposed DMER integrates a hybrid energy storage system (HESS) and an energy feedback system (EFS) to recycle RBE. Moreover, a hierarchical control strategy is presented. The upper control layer is an optimized operation model, which takes the state of charge (SoC), energy conservation, and the other parameters as constraints to utilize more RBE and achieve the minimum daily operation cost of substations. The lower control layer identifies the control strategy for multiple converters to ensure the stable operation and dynamic response of DMER. Finally, the effectiveness of the topology and control strategy is verified using field load data and experiments.

The adoption of electric vehicles at ports is a promising approach to achieve sustainability goals. However, realizing the full potential of this strategy depends on effective coordination between infrastructure planning and operational scheduling. In this paper, we propose a joint optimization framework that can co-optimize these two components to minimize the overall system cost. To capture the dynamic nature of scheduling decisions, we model the problem using dynamic programming techniques. Our model accounts for the spatial and temporal heterogeneities of charging and driving costs for different truck trips. To evaluate the effectiveness of our proposed framework, we conducted an empirical study at the Port of Los Angeles and Port of Long Beach. Specifically, we aimed to fulfill 5% of the daily 20-foot equivalent unit containers using electric drayage trucks. Our model identified the optimal number of electric trucks, charging stations, and truck schedules required to meet the container throughput requirement. We also analyzed the cost per container as a function of daily throughput level for various scenarios. Our findings provide insights on how to determine charger supply based on daily throughputs at ports, and how to choose the appropriate ratios of electric trucks and battery sizes in the truck fleet under different throughput and electric price cases.

With the development of intelligent vehicle technology, many studies have been focused on developing human-like trajectory planning methods for automated driving systems. Although data-driven methods are widely used for human driver behavior learning, there have been fewer studies on realizing human-like trajectory planning by using the generation mechanism of driving behavior, especially under curve conditions, where the lane centerline has been denoted as a reference trajectory. In this paper, thirty-two skilled drivers were recruited to collect data under different curve conditions on a self-designed driver-in-the-loop system. The collected data are processed by dynamic time warping, trajectories with different lengths are warped and the abnormal data are removed. Based on the warped data, common characteristics and differences between left and right turning trajectories are compared and explored from the perspectives of drivers’ demand for turning performance and their visual attention mechanism. Then, by introducing the driver preview mechanism, two features with a strong ability to represent the generation mechanism of the driver’s curve driving behavior are introduced. Finally, the preview-based human-like trajectory planning model (PHTPM) is proposed, and it is verified and analyzed by comparative tests and generalizability tests. The results show that the introduction of the driver preview mechanism enables PHTPM to match the characteristics of skilled drivers accurately on left turnings and outperform them on right turnings.

Integration of distributed generations that fluctuate widely (such as Photovoltaic panels, Wind power, Electric Vehicles and Energy Storage Systems), poses a chance to the stability of power technology and distribution structures. However, the primary reason is that the electricity ratio between supply and demand may not be balanced. An extra or scarcity inside the production or intake of electricity can disrupt the system and cause critical problems which include a drop/rise in voltage and, under difficult conditions, power outages. The use of Energy Management Systems can effectively increase the balance between supply and demand and decrease peak load throughout unplanned durations. The energy management system is capable of not only sharing or exchanging energy between the different energy resources available, but also of economically supplying loads in a reliable, safe and effective manner under all conditions necessary for the operation of the power grid. This work outlines the structure, goals, benefits and defies of the energy control system via an in-intensity analysis of the distinctive stakeholders and participants engaged on this system. A detailed essential analysis of the functioning of distinct programs which includes Demand Response, Demand Management and Energy Quality Management implemented inside the electricity management gadget is presented in this review. It also summarizes quantifications of the various strategies of uncertainty. It includes as well a comparative and an important assessment of the primary optimization techniques which are used to obtain the extraordinary goals of energy management structures while at the same time meeting a wide range of requirements.

This study summarizes a critical review on EVs’ optimal charging and scheduling under dynamic pricing schemes. A detailed comparison of these schemes, namely, Real Time Pricing (RTP), Time of Use (ToU), Critical Peak Pricing (CPP), and Peak Time Rebates (PTR), is presented. Globally, the intention is to reduce the carbon emissions (CO2) has motivated the extensive practice of Electric Vehicles (EVs). The uncoordinated charging and uncontrolled integration however of EVs to the distribution network deteriorates the system performance in terms of power quality issues. Therefore, the EVs’ charging activity can be coordinated by dynamic electricity pricing, which can influence the charging activities of the EVs customers by offering flexible pricing at different demands. Recently, with developments in technology and control schemes, the RTP scheme offers more promise compared to the other types of tariff because of the greater flexibility for EVs’ customers to adjust their demands. It however involves higher degree of billing instability, which may influence the customer’s confidence. In addition, the RTP scheme needs a robust intelligent automation system to improve the customer’s feedback to time varying prices. In addition, the review covers the main optimization methods employed in a dynamic pricing environment to achieve objectives such as power loss and electricity cost minimization, peak load reduction, voltage regulation, distribution infrastructure overloading minimization, etc.

The safety of lithium-ion batteries in electric vehicles (EVs) is attracting more attention. To ensure battery safety, early detection is necessary of a soft short circuit (SC) which may evolve into severe SC faults, leading to fire or thermal runaway. This paper proposes a soft SC fault diagnosis method based on the extended Kalman filter (EKF) for on-board applications in EVs. In the proposed method, the EKF is used to estimate the state of charge (SOC) of the faulty cell by adjusting a gain matrix based on real-time measured voltages. The SOC difference between the estimated SOC and the calculated SOC through coulomb counting for the faulty cell is employed to detect soft SC faults, and the soft SC resistance values are further identified to indicate the degree of fault severity. Soft SC experiments are developed to investigate the characteristics of a series-connected battery pack under different working conditions when one battery cell in the pack is short-circuited with different resistance values. The experimental data are acquired to validate the proposed soft SC fault diagnosis method. The results show that the proposed method is effective and robust in quickly detecting a soft SC fault and accurately estimating soft SC resistance.

The study carries out an economic technical analysis of the effect of the penetration of electric vehicles in a microgrid with various types of renewable energy sources and loads of different nature. The electric vehicle has been modeled through its main component, the battery, by using criteria of randomness in the entry and type of load used by each vehicle. Following this process, the energy demand curves and voltage profiles resulting from such penetration were obtained. In a second phase, three demand response programs based on incentives and prices were applied, and the impact of these decisions on the system through new demand curves and voltage profiles were quantified, the comparison with the base scenario is also carried out. In its final stage, the different scenarios proposed are evaluated financially and the NPV financial index is calculated, which is included in a binary-type optimization model, allowing through simulations to make decisions about the best demand response program alternative for the system.

In this article, a novel electric-drive-reconstructed onboard charger (EDROC) is proposed for the solar-powered electric vehicle (EV) that incorporates a six-phase machine drive. The power traction inverter and the machine are re-leveraged to implement charging operation, further minimizing the incremental mass accordingly. In particular, charging and driving operations can be simultaneously carried out via the vehicle-roof photovoltaic panels (PPs), significantly expanding EV mileage range. Firstly, the operation scenario and the topology of the proposed EDROC are introduced. Next, the operational principle is analyzed, as well as the indispensable conditions for safe and stable operation are studied. Thereafter, control schemes are designed and elaborated in terms of the simultaneous driving and charging mode and the DC charging mode. To this end, a 2-kW laboratory prototype is conducted, and experimental results are presented to verify the steady-state and dynamic behavior of the proposed EDROC system under different operation modes.

The ever-growing trend of making the traditional power grids smarter than before has resulted in their gradual evolution to more sophisticated grids, referred to as Smart Grids (SGs) Cyber-Physical Systems with complex networking technologies. The integration of Information and Communication Technologies with power grids fosters seamless data sharing between different SG entities, which supports effective and smart governance in terms of demand response management, frequency support, and voltage stabilization. Nonetheless, this integration opens up several security and privacy concerns, namely, electricity theft, power loss, battery exhaustion, infrastructure mapping, etc. These issues become even more important with the addition of distributed energy sources, e.g., electric vehicles (EVs), battery energy storage systems, and renewable energy sources, into the SGs. We present a framework based on Software Defined Networking (SDN) and BlockChain (BC) to address two challenging issues of EV-aided SG ecosystems, namely, privacy assurance and power security. We leverage the capabilities of SDN to handle the complex interactions between different subsystems of the SG. Furthermore, we also employ BC and smart contracts' properties to secure energy transactions and data communications. We design a secure and efficient mutual authentication protocol based on Elliptic Curve Cryptography (ECC) and BC for privacy preservation during smart energy trading. We also proposed a BC-based smart contract for effective Demand Response Management (DRM) during bidirectional energy transfer between EVs and SG. Finally, we present experimental evaluations to validate the proposed framework's performance. The results obtained demonstrate the improved performance of the proposed scheme compared with current state-of-the-art approaches. The mutual authentication protocol designed is not only secure against major attack vectors (namely, session key security, message integrity, anonymity, forward secrecy, and so on), but it is also cost-efficient in terms of communication and computational costs. Additionally, the SC designed assures power security and maintains an adequate balance between demand and supply.

This paper investigates the application of a vehicle‐to‐grid (V2G)‐enabled bidirectional off‐board electric vehicle (EV) battery charger on the grid current harmonic compensation (GCHC) and reactive power compensation (RPC) and simultaneously uses it as a battery charger and power generator. To generate reference current, the proposed EV charger control algorithm processed the nonlinear residential load current and point of common coupling (PCC) voltage, to estimate the active load current component and synchronizing voltage template, respectively. The EV charger control algorithm uses an adaptive notch filter (ANF) to generate the in‐phase and 90° shifted synchronizing voltage template from PCC voltage. Furthermore, a resonant filter is used to extract the fundamental frequency residential load current component accurately. The extracted fundamental component is sampled and hold at zero crossings of the 90° shifted synchronizing voltage template to estimate the active load current component. As a result, the proposed control algorithm ensures effective performance without depending on any phase‐locked loop (PLL). The charger performance with the proposed control algorithm is validated by the simulation results obtained using MATLAB/Simulink. Furthermore, an off‐board EV battery charger experimental prototype is built in the laboratory to verify the obtained simulation results. This paper investigates the application of a vehicle‐to‐grid (V2G)‐enabled bidirectional off‐board electric vehicle (EV) battery charger on the grid current harmonic compensation and reactive power compensation and simultaneously uses it as a battery charger and power generator. In operation, to generate reference current, the EV charger control algorithm extracts the synchronizing voltage template and active load current component from point of common coupling voltage and residential nonlinear current, respectively.

In recent days, deployment of Electric Vehicles (EVs) in automobile sector is increasing the load demand in the distribution system. To deal with this load demand, the charging management needs to be improved. Nevertheless, an EV needs several hours to complete charge. Reducing the charging time, energy consumption is a huge contest to deal with the promotion of EV over conventional vehicles. The condition of the itineraries may affect the energy consumption of the EV which needs to be considered before fulfilling the energy demand. In this paper, these are considered assigning suitable charging stations (CS) for corresponding EVs and their scheduling is taken as an optimization problem. The first part deals with the proper assignment of charging station which is a linear optimization problem and the second deals with the charging scheduling problem. An “Intelligent Charging Scheduling Algorithm (ICSA)” is proposed with the integration of Henry Gas Solubility Optimization to minimize total daily price incurred by charging station operator. Later, ICSA clubbed with other standard optimization techniques considering practical constraints. 2m Point Estimation Method (2m-PEM) method has been utilized to tackle the uncertainty and its performance has been compared with Monte-Carlo Simulation technique. The robustness of ICSA is evaluated and confirmed using Wilcoxon Signed rank test and Quade test.
