Partition distributed coordination optimization method containing multiple benefit subjects

Abstract

The invention discloses a partition distributed coordination optimization method containing multiple benefit subjects, which comprises the following steps: establishing a microgrid economic operationoptimization model and a virtual power plant income model based on second-order cone relaxation tide constraints; based on the modularity function of the electrical distance, utilizing a novel networkdivision method considering calculation complexity and power balance to obtain a power distribution network division result containing different benefit subjects; based on a network division result,coordinating different benefit subjects through a tie line ij, and connecting the tie line ij with the microgrid and the virtual power plant to obtain a distributed coordination model; according to the distributed solving method based on the alternating direction multiplier method, by introducing a Lagrange multiplier and applying a column and constraint generation algorithm, boundary variables are rapidly coordinated and updated, a distributed coordination model is solved, and an optimal decision result is obtained. According to the method, the optimization operation efficiency of the distribution network can be improved, and the operation cost can be reduced.

Description

technical field [0001] The invention relates to the field of power grid optimization operation control, in particular to a partitioned distributed coordination optimization method including multiple stakeholders. Background technique [0002] In the field of power grid optimization operation control, the development of the optimization system has gone through three stages. The first-generation control optimization system is called the local control system. Each part of the system is monitored by an independent control unit. Each unit is independent of each other and each completes its own goals. They cannot cooperate with each other and cannot realize the control process. Optimization, local control technology in power system, such as current protection, automatic switching control of reactive power compensation capacitor bank belongs to this category. With the improvement of computer processing capabilities and the development of communication technology, a centralized opt...
