Evaluation Model of Utilization Efficiency of Equipment Assets in Power Distribution Network Based on Order Relation-improved Entropy Weight Method
It is an urgent issue to reflect the utilization efficiency of regional distribution network equipment assets effectively. First of all, this paper establishes an evaluation index system of the utilization efficiency of equipment assets of distribution network with 16 evaluation indexes from four dimensions of policy conditions, economic conditions, load characteristics of equipment assets and grid structure based on the analysis of the development of regional distribution network and the utilization of equipment assets; secondly, with the help of the order relation- improved entropy weight method, each evaluation index is weighted, and the evaluation model of utilization efficiency of distribution network equipment assets is established; finally, the utilization efficiency of equipment assets in a distribution network in a certain region in north China is selected for evaluation, which provides reference value for the utilization of equipment assets and the improvement of grid economy in similar regions.
