Abstract:Due to the introduction of new photovoltaic energy,photovoltaic charging stations can both obtain profits by charging vehicles and benefits from grid power supply.Therefore,how to reasonably arrange charging to obtain the maximum benefit is the focus of charging strategy research.A deep confidence strategy gradient algorithm is used to optimize the charging strategy,using profit as a return function,and training agents,which can achieve online optimization without a priori.Finally,simulation experiments prove that the algorithm can achieve relatively high profits under different vehicles and different lighting conditions.
