摘要：
For the line expansion and source-storage siting and capacity of distribution networks with high proportion of distributed generators, this paper proposes a two-layer joint expansion planning method of grid-source-storage for distribution networks based on cluster partition. First, this paper proposes a multi-indicator distribution network integrated cluster partition method considering the electrical distance, cluster power balance, and cluster scale. Secondly, a two-layer joint expansion planning model is proposed based on cluster partition. The upper layer establishes the cluster line planning model to minimizie line investment and operation cost and realizes the optimization of cluster line orientation. The lower layer establishes the source-storage robust siting and capacity model for the uncertainty of source and load in the cluster, and introduces uncertainty regulation parameters to describe the range of source-load uncertainty set, so as to obtain the optimal access location and capacity of distributed generator and energy storage. Meanwhile, the conservativeness of the optimization results can be reduced. Finally, the effectiveness of the proposed method is verified by simulating and analyzing an actual photovoltaic distribution network in a certain region of China as a case. © 2023 Automation of Electric Power Systems Press.
