A Simulation Model and Control System of a Charging Station with Energy Storage

Abstract

The increasing use of electric vehicles is leading to a need to expand charging infrastructure. With no allowance for the state of the power system, this can lead to a shortage of power supply systems and local overloads in the network. In this paper, we propose a way to reduce the local impact of electric charging stations on the network by integrating a battery into the power supply scheme as a buffer storage device to reduce peaks in electricity consumption. We develop a simulation model of an electric charging station, which includes two main elements: a dc–dc converter and a rechargeable battery. An automatic control system of an electric charging station for charging modes with constant voltage and constant current is synthesized using the method of subordinate control systems. The synthesized control system meets the required quality indicators.
