PV based PHEVs smart charging station facility

The widespread applications of plug-in hybrid electric vehicles (PHEVs) established that there will be a massive inrush of PHEVs by the end of this century. There is a rising risk that this anticipation in the number of PHEVs will impose an extra burden in demand, especially at peak times and, therefore, threaten the stability of existing power grids. To satisfy the additional load of PHEVs, a smart charging station (CS) facility based on PV output power sensing due to the variation in solar irradiance and temperature is presented in this paper. The power required to charge the PHEVs is effectively managed from grid-connected photovoltaic (PV) generation. To confirm the optimal utilization of available power, charging time and grid stability, five possible switching modes have been considered for different interaction among the PHEVs, PV and the grid. Simulation results confirm the effectiveness of the proposed CS facility. The proposed CS and their controllers are designed in MATLAB/Simulink.
