Voltage Profile Enhancement of a 33 Bus System Integrated with Renewable Energy Sources and Electric Vehicle

Abstract

With the increasing rise in global power demand, it is becoming necessary to integrate renewable energy sources into conventional radial distribution systems (RDS). IEEE 33 bus RDS is considered in this study, with solar PV sources incorporated for power loss reduction, voltage fluctuation, and improve the system efficiency. For the purpose of charging and discharging, some electric vehicles (EV) are incorporated into the test system. The objective of the study is to analyze how EVs and Renewable energy sources (RES) affect the voltage profile in the RDS. As RES is introduced in the test system, the voltage profile is improved. To decrease voltage fluctuations, the usage of the hull moving average (HMA) is recommended, which avoids the lag problem associated with the commonly used moving average approaches. The genetic algorithm (GA) is used to solve the optimization problem accurately. The simulation results show that the suggested strategy is effective at smoothing voltage fluctuations while taking into account EV battery degradation and charging plans.
