Electric Vehicle Charging Station – Centered Regional Virtual Aggregation Technology in the Traffic-electricity-communication Integrated System

Electric vehicle interconnects traffic, electricity, and communication systems on account of its charging and intercommunication requirements. It causes the overlap of load hotspots in multiple systems and exacerbates the shortage of regional power supply. Firstly, this paper proposes a virtual aggregation mode to aggregate distributed resources and loads with charging station as the core node. Secondly, the constraints in both electricity networks and communication networks are built to develop the dynamic virtual aggregation strategy. Thirdly, case studies are conducted based on the real data of traffic-electricity-communication network in an area of Shanghai. The feasibility and effectiveness of the proposed technology are verified.
