Self-adaptive load transfer method and system for active power distribution network and medium

Abstract

The invention discloses a self-adaptive load transfer method and system for an active power distribution network and a medium. The method comprises the following steps: acquiring a plurality of load transfer strategies and a plurality of indexes, wherein each index is provided with a plurality of grades and a numerical value corresponding to each grade, and each load transfer strategy is provided with grades of a plurality of indexes corresponding to the load transfer strategy and corresponding numerical values; calculating a first weight vector, and obtaining the first weight vector according to the first pairwise comparison matrix of the plurality of indexes; performing second weight vector calculation on the plurality of indexes, and obtaining a second weight vector matrix of the plurality of indexes corresponding to the plurality of load transfer strategies according to a second pairwise comparison matrix of the plurality of load transfer strategies; according to the first weight vector matrix and the second weight vector matrix, obtaining a third weight vector through matrix calculation, and ranking all weight values of the third weight vector to confirm an optimal load transfer strategy. According to the embodiment of the invention, the optimal load transfer strategy can be calculated.

Description

technical field [0001] The invention relates to a power distribution automation system, in particular to an active distribution network self-adaptive load transfer method, system and medium. Background technique [0002] With the rapid development of urban smart grid construction, the construction of distribution automation system plays an increasingly important role in the safe operation of the power grid. The high-quality distribution network operation mode is a reliable guarantee for the safe operation of the power grid. During the construction of the distribution automation system, it is necessary to combine the local grid structure and the actual operation of the automation system operation platform, make overall plans, adjust the operation mode of the distribution network in a timely manner, and ensure the safe and economical operation of the distribution network. In this way, through the network advantages of the distribution network, the load interconnection and mutu...

Problems solved by technology

[0003] However, the current distribution automation system mainly uses basic rules to select the final path information through the analysis of the transfer path and the load calculation results, such as selecting a large transfer source line; the actual level of automation of the distribution network line and the health status of the equipment are not combined. Select the optimal load transfer strategy through comprehensive analysis of indicators such as historical failure disposal schemes
