Optimal Strategy for Electric Vehicle Charging Decision Considering “Source-Network-Pile”

Reducing carbon emission is a continuous goal of the new power system. Among numerous strategies of carbon emission reduction, optimizing the charging behavior of electric vehicles (EV) is of great significance to the stable operation of the power system as well as the reduction of carbon emission. This paper proposed a source-network-pile charging decision-making optimization strategy for EVs. Firstly, the photovoltaic (PV) source is introduced into the traffic-grid coupling network model, and the weight calculation method for “source-network-pile” is proposed. Then, a charging strategy for EV considering charging time, carbon emission, charging cost, operating state of coupling network and PV output is proposed. This strategy can reduce the charging queuing time of electric vehicles and reduce carbon emissions of power system. Finally, effectiveness of this strategy is proven by simulation conducted in Matlab.
