Design of Power Flow Management Controller for an EVs Charging Station with Distributed Renewable Energy Sources

Abstract

An Electric Vehicles (EVs) Charging Station (CS) that includes Energy Storage Systems (ESS) in addition to Hybrid Renewable Energy Resources (HRES) is the most profitable technique to fulfil the increasing electric demand. The accumulation of several RES and EVs need a systematic and elastic Power Flow Management Controller (PFMC). The stage 1 specifies the electric power distribution of Photovoltaics (PV), Wind, Battery, the Utility Grid and total EV charging power. Similarly, based on the available charging power specified in the stage 1, the stage 2 involves electric energy distribution among individual EVs. As a consequence, the two stage PFMC of the hybrid RES based EVs CS has been addressed consecutively. The proposed PFMC has been validated via simulation and its advantages are shown in the results.
