Steady State Analysis of Distribution System With Wind and Solar Under Various Electric Vehicle Load Models

This work proposes a load flow analysis based on backward and forward sweeps to evaluate the effects of electric vehicle (EV) loading on a distribution system powered by distribution generation technologies like solar and wind. The simulation has been done on an IEEE-33 bus system. The simulation outcomes demonstrates the impact of integrating distribution generations at the grid and EV load models with impact levels ranging from low to high for voltage dependent loads (EV2), constant current load (EV3) and polynomial load models (EV1), respectively. The study explores the various issues of incorporating EV loads with renewable energy sources (RES) and evaluates proposed solutions for their proper integration in distribution network. The study also assesses several modelling sections of the studied system in order to assist researchers in modelling these kind of systems for research purposes, as well as to comprehend and quantify the constraints for integration techniques.
