Energy/reserve sharing dispatch for interconnected multiple microgrids based on adaptive robust optimization

To solve coordination problem of multiple interconnected microgrids under deregulated power market, an energy/reserve sharing dispatch method was proposed based on cooperation game theory. Joint day-ahead energy/reserve dispatch models for singlemicrogrid and for a group of microgrids were proposed. Adaptive robust optimization was employed to solve these dispatch models. To guarantee each microgrid's benefit and coalition stability, convex game theory was applied to distribute benefits among multiple microgrids. Compared with results of two-stage robust optimization and Monte-Carlo simulation, conservatism and feasibility of adaptive robust optimization was demonstrated. Finally, feasibility of convex game to distributed benefits was verified with simulation results of a group of three microgrids.
