Economic Operation Optimal Model of Distributed Photovoltaic Energy Storage Participation in the FM Auxiliary Service Market

In distributed PV large-scale access to the distribution network leads to the increasing demand and pressure of grid FM, this paper proposes a distributed photovoltaic storage economic operation optimization two-layer model considering distributed PV energy storage cost and FM auxiliary service cost. First, combined with the characteristics of distributed photovoltaic and energy storage, the conditions they need to meet to participate in FM are clarified. Second, a market mechanism for distributed PV and energy storage to participate in FM involving two trading standards of FM capacity and FM mileage is proposed. Then, a two-layer model of economic operation optimization for distributed PV storage participation in the FM auxiliary service market is constructed based on the framework of this market mechanism in order to maximize the net return of distributed PV. Finally, the effectiveness of the proposed method is verified by arithmetic examples. The results of the arithmetic examples show that the framework and model of this paper can optimize the allocation of distributed photovoltaic storage and improve its economic benefits.
