Application of Improved Cluster Division Method in Active Distribution Network

A large number of distributed power sources based on photovoltaics are connected to the distribution network, which makes the power system require various components to actively participate in the management of the grid, which constitutes the basic principle of the active distribution network. Active management is one of the main characteristics of the active distribution network. This paper adopts the strategy of cluster division, divides the active distribution network into multiple relatively independent clusters, and establishes a distribution network partition index based on the load absorption index. A zoning strategy aimed at reducing source and load collaborative complementary scenarios. Considering the uncertainty of load and photovoltaic at the same time, the effectiveness of the proposed method is verified in the 60-node distribution network example.
