An Aggregator for Energy Dispatch among Plug-in Electric Vehicles for V2X Application

This paper presents the development of an electric vehicle (EV) aggregator which has several objectives with conflictual constraints. It considers the communication between grid operator and aggregator, fair distribution of available energy to perform EV to EV and EV to grid energy exchange. The algorithm also considers preserving the batteries lifetime against intense discharges as well as the customer's preferences in terms of unidirectional/bidirectional charging options considering minimal state of charge (SoC). Furthermore, the algorithm was tested using three different scenarios: full charging capability operation, operation under limited resources, and operation in V2V and V2G modes. The results show that the developed aggregator favor the vehicles recharge with lower SoC, and the discharge priority favor the vehicles with the highest SoC while respecting the customers' declared preferences.
