The present invention relates to the differentiated planning technology of electric power system, in particular to a method for constructing a core backbone grid based on the TLBO algorithm, respectively constructing branch and node importance evaluation index systems based on risk theory and complex network theory, and based on entropy weight-TOPSIS method Calculate the weight of each index; calculate and sort the importance of components, and connect all important load nodes based on the minimum Steiner tree; build an optimal configuration model of units with the objective function of maximizing the ratio of new energy output income and core backbone grid operation risk, and adopt improved The binary TLBO algorithm is used to solve the problem, and the construction plan of the core backbone grid is obtained. This method expands new ideas for the construction of the core backbone grid, provides a reference for the power grid planning department to formulate differentiated planning schemes, and is conducive to improving the adaptability of the power system under the trend of large-scale new energy access.
Description
technical field [0001] The invention belongs to the technical field of power system differential planning, and in particular relates to a method for constructing a core backbone grid based on a TLBO algorithm. Background technique [0002] The purpose of differentiated planning and design is to ensure continuous power supply to important loads when major natural disasters occur. The core content of differentiated planning is the construction of the core backbone grid. In recent years, due to the large-scale new energy access to the power system, the uncertainty of the power system at both "source" and "load" has increased significantly, and the stable operation of the system has been greatly challenged. It is difficult to identify key branches and nodes. Increase the core backbone network The difficulty of constructing the frame. The construction of the core backbone grid is a nonlinear and discontinuous optimization problem, which depends on artificial intelligence algorit...
