Evaluation method based on gridding power distribution network

Abstract

The invention provides an evaluation method based on a gridding power distribution network. The evaluation method comprises the following steps of: determining division principle of a regional grid power distribution network ; setting three types of power distribution network evaluation indicators of a first-grade grid, a second-grade grid and a third-grade grid; refining the three types of power distribution network evaluation indicators and calculating each indicator; dividing the indicators according to the coordination, safety and diversity of the power distribution network, and calculating an indicator weight by using a fuzzy entropy method; and repeating the steps to obtain a comprehensive evaluation value of the gridding power distribution networks of different regions. The evaluation method based on the grid power distribution network has the beneficial effects that with a construction thought of "refining the power distribution network from bottom to top", the requirements on the power supply reliability are met grade by grade in terms of the requirements of users, so that the self-management and self-healing capability of the power distribution network is improved; and the evaluation method is suitable for analyzing a power supply environment of the gridding power distribution network and an evaluation result can provide decision-making basis to an intelligent power distribution network.

Description

technical field [0001] The invention belongs to the field of distribution network evaluation methods, in particular to an evaluation method based on a grid distribution network. Background technique [0002] As an important infrastructure for economic and social development, the power grid is a physical platform for energy conversion and power transmission; at the same time, the power grid is also an important carrier for optimizing the allocation of large-scale resources and promoting market competition. With the continuous expansion of urban construction scale and the continuous improvement of municipal functions, grid development requirements are put forward for the development of urban distribution networks. Grid distribution networks can promote urban economic development and improve the problem of difficult electricity consumption for enterprises. At the same time, it can effectively solve the contradictions in the production organization, business charges and power gr...

Problems solved by technology

However, the existing evaluation methods for distribution networks are not suitable for grid distribution networks. It is difficult to take into account the technical and economic factors of the power grid as a whole, and it is even more difficult to reflect the comprehensive social benefits of the power grid. Problems in the evaluation are not conducive to stable power supply. Will increase the difficulty of maintenance and management of workers
