Research on Case Library Construction of Energy Loss in Country Distribution Networks with Grey Relational Analysis

Abstract

Some factors affect the energy loss in country distribution networks, including the load density, the load distribution, the grid structure and the operating condition of the distribution networks. As a result, the difference and the relation among these loss effect factors are considered, and the typical case library of energy loss in the distribution networks is built. On the basis of building some loss analysis scenes, the method of Grey Relational Analysis is used to evaluate the influence degree between energy loss rate and reference factors. The analysis software of the case library is developed and applied. Case studies show that there is some difference to these factors among different distribution networks and the difference can be suggested with the method, which provides a way to form the differential scheme of saving energy and reducing loss. Influence Factors Analysis According to the difference of the country distribution networks, the specific conditions of the regional distinction should be considered to study the influence factors that affect the energy loss in

“…The evaluation of the GRA is based on the relevancy between the evaluated scheme and the comparatively ideal scheme. The optimal data column Y 0 (k) was selected from the value of the evaluation matrix indexes Y [93]. The steps for calculating the relevancy are as follows:…”
