The article discusses the issue of expanding the methodological foundations of system reliability of electric power systems as part of the development of a new type of system reliability - planned reliability. Planned reliability is a type of system reliability intended for the analysis of electric power systems when planning their operation for a...

This article discusses the problem of planning maintenance of power equipment during long-term planning of the operation of electric power systems. Here we propose a mathematical model for the formation of maintenance schedules for power equipment, which takes into account two aspects: the current technical condition of power equipment and maximizi...

The paper presents the main components of a methodical approach to assessing the level of significance of critical energy facilities on the example of individual outages of the most important facilities of the Russian gas transmission network. Approaches to modelling the fuel and energy complex of the country and its constituent energy systems: gas...

The article deals with the problem of generating calculation models (CM) of electric power systems (EPS) into reliability zones, designed to perform calculations of adequacy assessment indicators. The substantiation of the depth of detail of the CM is based on taking into account two properties of the EPS: reliability, namely, on the basis of calcu...

In our research, we focus on the reliability of the interconnected electricity supply system of three countries of the Eurasian Economic Union (EAEU)—Russia, Kazakhstan, and Kyrgyzstan. We apply a mathematical model to evaluate the reliability of the electricity supply system under the threat of earthquakes. Earthquakes can damage elements of elect...

Modern electricity consumers place increasingly high demands on the level of reliability of power supply and, correspondingly, the reliability of electric power systems (EPS). These requirements should be directly addressed in the EPS development planning tasks. To this end, the evaluation of the level of EPS reliability is performed by employing s...

Based on the experience of domestic and foreign researchers, it is known that there are various mathematical models, software systems, and optimization methods used to solve the set tasks for assessing the resource adequacy of electric power systems (EPS). However, the continuous development of EPS leads to the complication and integration of syste...

The article considers the question of increasing the computational efficiency of the procedure for electric power systems adequacy assessment using the Monte Carlo method. In the framework of using this method, it is necessary to randomly generate a certain number of system states. As it is known the speed and accuracy of the calculation depends on...

The paper deal the problem of definition and ranking of critical objects (CO) in electric power systems (EPS). The identification of the CO is necessary for the timely adoption of measures to organize the provision of the required level of energy security of the region where the object is location. The adequacy model is used for determine the criti...

The paper deals with the problem of the accounting of renewable energy sources and energy storage systems in assessment of power system adequacy. Development of renewable energy sources and energy storage systems in the present day power systems is one of the main focuses. In power systems of some countries the share of electric energy generated by...

We suggest an algorithm to optimize reliability of an electric power system. The algorithm uses the averaged dual estimates of power generation and power flow constraints. The average values of dual estimates are found by analyzing electric power system reliability. The developed algorithm is based on the enumeration of alternative system reconfigu...

In this paper we deal with the problem related to effective assessment of reliability of electric power systems, particularly, the effi ciency of pseudorandom number generators while using the Monte Carlo method for generation of random states of electric power systems. We consider the efficiency of four pseudorandom number generators: linear congr...

The paper is devoted to a topical issue of determining the required total capacity reserve for a given level of adequacy in the operation of the Interconnected Power System of Russia. This paper places an emphasis on a close interdependence between adequacy and total capacity reserve. The higher the adequacy, the larger the reserve should be. We pr...

The article presents an algorithm for obtaining sensitivity models of the first and second orders of the steady-state regime of electric power systems (EPS). The sensitivity models are intended for express calculations of steady-state when estimating the static security of EPS. The use of sensitivity models allows one to simulate failures of EPS el...

We describe the algorithm for the adequacy discrete optimization of electric power systems (EPSs). The algorithm is based on the expectation of dual-use estimates obtained when evaluating the EPS carrying adequacy through the Monte-Carlo method based on restrictions of generating capacity in the EPS nodes and communication capacity of EPS. The deve...

The paper formulates possible statements of the problem of optimizing the adequacy of electric power systems (EPSs). The authors present a general algorithm for EPS adequacy optimization and consider original methods for the EPS adequacy optimization, that are based on artificial manipulation of consumer load. Practical application of the presented...
