An optimal scheduling strategy for microgrid considering the CDRS and CECS of prosumer

Abstract

With the deepening integration and interaction of the prosumer's "sourceload-storage," for a microgrid (MG) with prosumers, the comprehensive demand-side response (CDSR) of the prosumer's multiresources is conducive to improving the system's new energy consumption，economic benefits, and prosumer's comprehensive electricity consumption satisfaction (CECS) of multiresources usage. Consequently, an optimal scheduling strategy for the MG with prosumers is proposed in this article, considering the CDSR and the CECS of the prosumer. In addition, a master-slave game model with the MG as the leader and the prosumer the follower is established, to stimulate the activity of prosumers participating in the scheduling by bargaining the price of the MG. Taking the maximum operation benefit as the optimization objective, the MG formulates the electricity price incentive policy to encourage prosumers to participate in the MG's peak adjustment dispatching; responding to the MG's price policy, the prosumer develops the scheduling strategy to minimize its total cost and maximize the CECS. After multiple rounds of iterative optimization, the Stackelberg equilibrium is obtained, while two parties are unable to obtain greater benefits by adjusting their own strategies. The simulation results show that the prosumer with the CDSR and the CECS may obtain the best scheduling performance, and the interests of the whole system are promoted with the proposed strategy.
