A Coordinated Charging Scheduling Method for Electric Vehicles Connecting to Microgrid Considering Emergent Charging Demand Kaile Zhou*, Lexin Cheng , Xinhui Lu

Abstract

In this study, a coordinated charging scheduling model for EVs connecting to microgrid is proposed to achieve peak shaving and valley filling. In the model, we develop an EV Charging Emergency Indicator (CEI) that used to measure whether the EVs have emergent charging demand. For the EVs that have emergent charging demand, the emergent charging strategy is employed. Considering the emergent EV charging, the optimal dispatch model including all the EVs (both emergent charging EVs and usual charging EVs) is developed. The objective of the model is to minimize the overall peak-valley load difference. The proposed model considered both the randomness of the EVs connected to the microgrid and the emergent charging demand of some EVs. Finally, the simulation results show the effectiveness of the proposed model.
