Abstract

The application provides a method for coordinating distributed power flow optimization of the main distribution network and related equipment, wherein the method of the application includes: according to the topological relationship of the distribution network system model, the distribution network system model is divided into a main network model and a distribution network model Model; according to the preset power flow optimization target threshold, the main distribution coordination power flow optimization model is established, and the main network ADMM iterative optimization model and the distribution network ADMM iterative optimization model are respectively established through the alternate direction multiplier calculation method according to the main distribution coordination power flow optimization model ; The main network ADMM iterative optimization model and the distribution network ADMM iterative optimization model are iteratively calculated to obtain the current main network optimization parameters and distribution network optimization parameters. This application is based on the target-synchronized alternating direction multiplier method of the master-coordinated distributed power flow optimization method, which does not require a unified upper-level optimization center, and solves the calculation and communication bottleneck problems of the existing centralized optimization degree method with a distributed calculation mode , which improves the power flow optimization efficiency of the main distribution coordination.

Description

technical field [0001] The present application relates to the field of distribution network management optimization, in particular to a method for coordinating distributed power flow optimization of a main distribution network and related equipment. Background technique [0002] As massive distributed flexible loads are connected to the distribution network, the operation mode of the actual distribution network has undergone tremendous changes. The traditional dispatching mode can no longer meet the actual operation needs. Regulating a large number of multi-variable flexible loads, so as to achieve the balance between the supply side and the demand side of the distribution network, and realize the optimal dispatch under the access of massive distributed flexible loads, has become an urgent problem for electric power workers to solve. [0003] At present, the optimal scheduling methods of the main network and the distribution network are all centralized optimal scheduling met...
