Grid Connected Electric Vehicle Charging Station with Multi Renewable Source

Abstract

In this paper the battery of one or multiple electrical vehicles are charged when connected to conventional three phase grid through controlled rectifier and DC-DC converter. The conventional grid is integrated with multiple renewable sources which include PVA and wind farm. The battery charges utilizing maximum power from the aforementioned renewable sources. During deficit renewable power conditions three phase grid provides power for battery to charge through rectifier. The energy management control structure for the test system including grid with domestic loads, EV charging station, renewable sources is modeled. Different operating conditions with variable environmental factors impacting the renewable sources and EV battery charging are analyzed using MATLAB Simulink software. Graphical representation with time as reference is done using 'powergui' toolbox.
