Abstract

The invention provides a power distribution network immunity influence factor index weight calculation method and system. The power distribution network immunity influence factor index weight calculation method comprises the steps of obtaining power distribution network immunity influence factor index values in a pre-constructed index system; calculating an index integral row vector of each layer in the pre-constructed index system by adopting an improved analytic hierarchy process based on the power distribution network immunity influence factor index value; determining a power distribution network immunity influence factor composite weight of each layer based on the index integral row vector of each layer; wherein the index system is constructed by taking the power distribution network immunity influence as a first-level index layer, taking the index which influences the power distribution network immunity as a second-level index layer, and taking the influence factor of the index which influences the power distribution network immunity in the second-level index layer as a third-level index layer. According to the method, the improved analytic hierarchy process is adopted to calculate the composite weight of the power distribution network immunity influence factors of each layer, so that the calculated index weight is more accurate.

Description

technical field [0001] The invention relates to the field of intelligent distribution networks, in particular to a method and system for calculating the weights of factors influencing immunity of distribution networks. Background technique [0002] Self-healing is a distinctive feature of smart distribution network that is different from traditional distribution network. With the construction and development of smart distribution network, research on how to improve the self-healing capability of distribution network has received extensive attention. How to accurately evaluate distribution network The overall immunity level is an urgent problem to be solved. The immunity of intelligent distribution network refers to the ability of the distribution network to resist operational risks, effectively deal with faults, and quickly restore power supply. The study of the distribution network immunity evaluation index and its weight calculation method is the basis for accurately evalu...
