Design optimization of PHEV charging station

Plug-in hybrid electric vehicle is one of the most feasible approaches towards significantly lowering the consumption of oil and improve fuel economy with today's existing technology. The paper focuses the design optimization of the PHEV charging station with battery storage units. The battery units conserve the low price clean energy and discharge when demanded. The on-site installed photovoltaic (PV) and off-site (virtual) wind farm are the main supply of charging station to charge the battery units. The grid electricity plays an auxiliary role in the station when the renewable sources and the demands are unbalance or the trading provides economic benefits to the charging station. The paper examines the PHEVs charging trend, and proposes an optimized operation for the battery storage schedule, and strategy of power trading to minimize the cost of station. Analysis based on level of forecast uncertainty is utilized to evaluate the optimization.
