Energy Management Strategy for Grid Connected Solar Powered Electric Vehicle Charging Station

Abstract

Solar powered Electric vehicle (EV) charging stations are being widely adapted in the present-day scenarios. But the problems with varying irradiance for photo-voltaic (PV) systems, peak load, and disturbances due to grid penetration of PV and EV needs to be addressed. In this paper a PV powered electric vehicle charging station with an intelligent energy management strategy (EMS) is developed. The energy management approach adapts meteorological data and load demand statistics to optimize the use of solar and grid energy for charging station. The EMS controls the power flow between the PV, grid, battery and EV charging station resulting in reduced power demand peak by a factor of 2.
