Partition decoupling model and method in power distribution network, part II: A novel partitioning optimisation operation method

Abstract

In this study, a partition optimisation method for distribution network is proposed to realise decoupling coordination, which provides a research basis for optimising power flow and operation regulation. Firstly, a partition model of distribution network is established, in which the electrical distance, parallel computing efficiency, and operation stability indexes are considered at the same time; Secondly, the AHC algorithm is used to realise the automatic search partition of the distribution network, and the class spacing measurement factors of point-to-point, cluster-to-cluster are considered in this method. Finally, the Distributed Sequential Quadratic Programming for Distributed Generation (DSQP-DG) is introduced, and the parallel decoupling coordination of the distribution network is realised by alternate iteration of its inner and outer layers.
