Power grid coordinated development evaluation method for power system

Abstract

The invention relates to a method for evaluating the coordinated development of a power grid in a power system. Firstly, on the basis of constructing a comprehensive evaluation index system of a two-level intelligent power grid, the initial weight of the index system is obtained through the analytic hierarchy process. Then, by analyzing the development differences of each secondary indicator, the coordinated development coefficient of the indicators is calculated, and the evaluation value of the secondary indicator is revised; and the weight of the primary indicator is revised by analyzing the regional differences; finally, according to the revised indicator evaluation value and weights to evaluate the coordinated development of the power grid. The invention solves the problem that the weight is difficult to set under the uneven development of regions, can propose more scientific policy suggestions for the relevant regions, rationally develop the smart grid on the basis, and ensure the healthy and coordinated development of the smart grid.

Description

technical field [0001] The invention relates to a management and evaluation theory of a power system grid, in particular to an evaluation method for the coordinated development of a power system grid. Background technique [0002] The construction of power grid is a long-term, complex and huge system engineering. Under the wave of intelligent power grids, comprehensive and scientific evaluation of the comprehensive benefits of power grids, and timely discovery of weak links and restrictive factors in the development of power grids are of great practical importance for correctly guiding the planning, construction, operation, and management of regional power grids under the background of the new economic normal. significance. [0003] The evaluation of power grid development coordination is one of the effective means to investigate the robustness of power grid development. Compared with other evaluation methods, the evaluation of power grid development coordination has the fo...

AI Technical Summary

Problems solved by technology

[0004] At present, the existing evaluation methods for the coordination of power system and power grid development are not perfect for the selection of the index system, and have not fully considered the correlation of the index system and the development differences between regions. It is difficult to obtain satisfactory control effects, and the trend analysis is not strong.
