Research on Situation Evaluation and Prediction Method for Distribution Network

As the important link between transmission network and end users, the operation status of distribution network directly affects the economics, customer service and reliability. With the development of smart distribution network, more and more attention has been paid to the operation situation of distribution network. In this paper, a practical distribution network operation evaluation and prediction method is proposed. Firstly BSC (Balanced Scorecard) based KPIs are created so as to provide fully vision on distribution network situation evaluation. Then AHP method is used to determine the index weight and situation evaluation is performed. Based on the evaluation method and result, Gray theory method is applied for situation prediction of distribution network. The proposed evaluation method in this paper can help operators grasp the operation situation of distribution network and provide effective guidance for decision support.
