Optimization of EV Charging Amount in Microgrids Using Stackelberg Game

This paper proposes a framework for compensating fluctuations of renewable energy generation by adjusting charging amount of Electric Vehicles (EV) in a microgrid. We have three purposes: matching supply and demand, minimizing the microgrid's cost, and maintaining the convenience of EV while adjusting charging amount depending on the generation from renewable sources. In order to achieve these purposes, we propose two-stage framework, Stackelberg-game approach, and considering expected utility of EV. As a result, the microgrids could determine their energy management strategy while considering their cost and EV's convenience, and therefore positive economic effect has been created, matching supply and demand.
