A method is presented for fractional-octave smoothing that, for spectra that are originally symmetric in log-frequency, preserves said symmetry after smoothing. Unlike an existing method, which requires interpolation of the FFT spectra to a log-frequency scale, the proposed method uses analytically-derived smoothing windows and operates directly in...

... Variation in solar power is captured by the test systems placed at a location within the DS. The test system provides data of hourly power generated by it, and this data are used to calculate the hourly power variation in each season similar to load variation as shown in Fig. 3 [79]. For example, solar power generated during the interval 09:00 AM to 10:00 AM in winter weekday is found by taking the average of power generated on all weekdays in winter season during the same interval. ...
... If the hourly power generated data are not available, then it can be estimated using solar insolation data of the area. The solar data used in this paper was obtained from a 100 kW peak solar PV plant installed at the rooftop of IIT Kharagpur [79] (see Appendix Table A2). In the absence of such data the power generated by the test system can be estimated from the solar insolation data using the following equation [80], ...

Renewable energy sources are becoming popular day by day for distributed generation as technology is becoming cheaper and modular. Power loss reduction is a powerful incentive for a distribution system operator to promote distributed generation. This paper presents a method to minimize annual energy losses through the integration of nondispatchable renewable distributed generation (DG) units and network reconfiguration under varying load demand condition. The optimal location and DG power level are calculated, and then these data are used to determine DG plant size taking into account the nonavailability of renewable energy at certain times. A network reconfiguration strategy is proposed, which takes into account both the time‐varying load and the renewable energy source such that annual energy loss is minimum. The proposed methodology is applied to 33‐node and 118‐node test distribution system with different scenarios. Results show a substantial reduction in energy loss. A cost‐benefit analysis is also carried out.

... where VPV is the terminal voltage of PV cell; IPV is the terminal (output) current of the cell; IPH is the photocurrent generated by the cell due to sun irradiance; VT is the thermal voltage of the diode; IS is the diode saturation current. Fig. 2 are in accordance to the kit manual [14]. The photocurrent proportional to the sun irradiance is simulated by a voltage from the potentiometer P1 operating as a voltage divider where the voltage of 10 V is corresponding to the sun irradiance of 1000 W/m 2 (e.g. 1 V is equivalent to 100 W/m 2 ). ...
This paper discusses modelling and parameters investigation of a photovoltaic array using Analog System Lab Kit Pro board offered by Texas Instrument for instructional laboratories on Electric and Electronic Engineering. The modelling of PV array is based on representation of the current-voltage characteristic by an analogue circuit developed using the components available on the Lab Kit board. The model is applicable for instructional laboratory investigation on the array current-voltage characteristic and its performance at maximum power point. This investigation expands the portfolio of the laboratory works available through Analog System Lab Kit Pro board.
Education technology for electronic hardware testing was combined in the form of an analog/mixed signal development kit with miniaturized testing instrumentation to explore oscillator and PLL designs, operating at audio frequencies. The hardware demonstrated second order effects, such as multiplier nonlinearities, that are sometimes neglected in a first pass design. 7 lock-in ranges for the PLL were observed. Circuit redesign to enable the analog kit to operate in both dual supply and single supply mode was demonstrated. Analog circuit design as needed for Software Defined Radios (SDR) was also explored.
