ANFIS Controlled Grid Connected Electric Vehicle Charging Station Using PV Source

摘要

This paper provides an insight of electric vehicle charging station which is supplied by three sources grid, photovoltaic system (PVS) and battery energy system (BES), and this system works in both conditions like shore and offshore. Power grid, equipped with an AC/DC converter supplies a continuous and constant power to EV charging station through a DC/DC converter. BES used as a buffer by storing excessive energy at light load conditions and supplying it when needed. Control unit enables the bi-directional DC/DC converter for charging and discharging. Adaptive neuro fuzzy inference system (ANFIS) is used in control unit which improves the performance of the converters. MPPT (maximum power point tracking) technique is used to get the appropriate pulses for DC/DC converter to extract the maximum output power from PVS at different conditions. The proposed system is simulated in MATLAB/SIMULINK environment and results are discussed to validate the system.
