Optimal Integration of Distributed Generators and Electric Vehicle Charging Stations in the Distribution System Using Voltage Stability Index and Political Optimization Algorithm

Distributed Generation (DG) integration into the radial distribution system (RDS) is persuaded by the steadily rising demand for electrical power and the challenges in meeting that demand utilizing conventional power-generating sources. The increased penetration of electric vehicle charging stations (EVCS) into the DS makes the charging process more difficult. But, depending on the need, if the utility uses EVs to support it, it turns out to be favourable. To address the distribution challenges faced by DGs and EVCS in the DS, this research proposes a multi-pronged hybrid approach based on the voltage stability index (VSI) and political optimization algorithm (POA). This study also examines the effects of EV operation and DG installation on conventional IEEE 33 bus distribution networks in an effort to decrease power losses (PLoss) and improve the DS’s voltage profile across the system. The analysis is also carried out for an intermittent 24-h load profile with various dynamic charging approaches from Grid to Vehicle (G2V) and Vehicle to Grid (V2G). The results are compared with the possible cases.
