Distributed generation to mitigate the impact of electric vehicle charging stations on distribution networks

Integrating electric vehicle charging stations (EVCS) into the energy distribution network presents significant challenges. A wide range of work has been carried out to understand this possible impact and, in particular, to assess the loading capacity of distribution networks, with or without network management solutions. A high concentration of EVs can increase peak demand, leading to higher energy losses, voltage drops, etc., which can reduce the efficiency and reliability of power distribution. This article focuses on the impact of integrating EVCS into the power distribution network and the deployment of distributed generation (DG) to mitigate these challenges.In this study, the Whale Optimization Algorithm (WOA) and moth-flame optimization (MFO) are adopted to select the optimal size and location of distributed generation on the distribution network in the case of EVCS integration to reduce energy losses and improve the voltage profile. Analysis is carried out on the IEEE 33 bus distribution network.
