Abstract

The invention discloses a power transmission planning to-be-selected set optimization method and system based on redundancy constraint identification, and is used for obtaining a minimum-scale to-be-selected line set meeting planning requirements, reducing a solution space for the calculation of a subsequent power transmission network planning problem, and improving the calculation efficiency. The method comprises the following steps of: checking the connectivity of a net rack, adding lines to a test net rack on the basis of a redundancy constraint identification method to obtain an initial optimized to-be-selected line set, and finally performing line reduction correction on the test net rack on the basis of the redundancy constraint identification method to obtain a minimum-scale power transmission planning to-be-selected line set. According to the method, an optimization problem does not need to be additionally solved, and the method has high efficiency for formulating a complex large-scale power system power transmission planning to-be-selected line set.

Description

technical field [0001] The invention belongs to the technical field of power transmission network planning, and in particular relates to a method and system for selecting a power transmission planning candidate set based on redundancy constraint identification. Background technique [0002] With the proposal of the dual carbon goal, the power system is undergoing energy transformation. The large-scale grid connection of new energy represented by wind power and photovoltaics requires an urgent need for transmission grid planning to ensure that the power system can accommodate a high proportion of new energy. For the provincial power system, the grid frame is huge and contains a large number of components, which greatly increases the difficulty of transmission network planning. [0003] For transmission network planning, most studies focus on how to improve the computational efficiency of the planning model, while few studies on the optimization of the line set to be selected....
