Abstract: Currently,distributed photovoltaics（PVs） on the user side are showing a low-end quantitative expansion trend of decentralized construction and disorderly access,which is difficult to meet the needs of large-scale deep development and sustainable development of distributed PV power generation under the low-carbon transformation of the power grid.This paper explores the integrated development and operation mode of distributed PV clusters,and proposes a game strategy for cluster development of users-side distributed PV resource.Firstly,a distributed PV cluster development and operation model with cluster operators as the main body is constructed.Secondly,a prediction method for user PV development behavior is proposed for two development modes:self-built PV or rented site.Then,the game relationship between cluster operators and users in the allocation of PV development resources is revealed,and a two-layer optimization model of distributed PV resource Stackelbery game is constructed.Finally,the simulation results validate the effectiveness of the proposed method in guiding the orderly and rational development and reasonable and efficient configuration of user-side distributed PV.
