Electric Vehicle Charging Station for Solar PV Based Grid Interactive System

Abstract

A transition from fossil fuel-based vehicles to electric vehicles (EVs) is increasing manifold with an increase in green energy implementation. In view of it, an EV charging system (EVCS) based on solar photovoltaic generation is presented here, with EV charging/discharging capabilities during base/peak load periods, respectively. For an EV charging system based on solar array, a fractional Lagrange filter is utilized here, thereby, improving the power quality of the distribution network. Furthermore, in order to guarantee an improved power quality (PQ), the grid currents are analyzed in covenant with the IEEE-519 standard. The EV charging mechanism is also obtained during grid absence through the usage of a voltage controller. The validation of the system performance is obtained via hardware in loop implementation through OPAL-RT platform, during various weak grid conditions.
