Multi-source power converter system for EV charging station with integrated ESS

Abstract

This paper deals with the optimal sizing and power flow control for grid-connected multi-source power converter system for EV charging infrastructure with integrated energy storage system. The sizing of the power conversion system is based on cost-benefit analysis which takes into account several factors to define the e-mobility scenario and different topologies of power conversion units. The proposed solution allows minimizing the impact of EV charging processes on the electric grid as well as their cost by means of suitable use of a renewable source and an energy storage system.
