Electric vehicle charge scheduling (EVCS) with PV assistance for variable energy purchase in a multi-aggregator environment

Abstract

With the anticipated growth in use of electric vehicles (EVs) due to their benefits in environmental conservation and their potential as an energy storage device, corresponding charging facilities will also observe a growth. EVs require a charging infrastructure that supports a scenario which is capable of handling a large number of scheduling requests. However, this may result in a greater load on the grid. To mitigate the impacts of the increased charging load on the grid, photovoltaic (PV)-assisted charging stations, or PVCS, are proposed here. The benefits of PVCS are evaluated from the point of view of aggregator profits and energy consumption from the grid for a greater number of scheduling requests. With the use of PV at charging stations, it is found that for the period in which PV and battery storage are active, a majority of the charging requests are scheduled through the PV/Battery assist. Thus, reducing the effect on the grid along with an improvement in the total profit of the aggregators.
