Question

what is the impact of level ll electric vehicle charging station in distribution grid, in transformer overloading and harmonic distorsion ? And how to prevent the impact?

please write a lot of argument not just short answer, or mention a good peper to help me deep understand . i want work on project regarding this issue.

thanks

Answer 1

Recent concerns about environmental pollution and escalating energy consumption accompanied by advancements in battery technology have initiated the electrification of of the transportion sector. With the universal resurgence of electric vehicles(EVs) the adverse impact of the EV charging loads on the operating parameters of the power system has been noticed. The detrimental impact of EV charging station loads on the electricity distribution network cannot be neglected . The high charging loads of the fast charging stations results in increased peak load,demand,reduced reverse margins,voltage instability,and reliability problems. Further,the penalty paid by the utility for the degrading performance of the power system cannot be neglected. This work aims to investigate the impact of EV charging station loads on the voltage stability ,power losses reliability indices, as well as economic losses of the distribution network. The entire analysis is performed on the IEEE 33 bus test system responding a standard radial distribution network for six different classes of EV charging station placement .
