Abstract Distribution network operation status is characterized by many operation indicators, but the importance of different indicators varies. It is necessary to identify the distribution network operation status by scientific methods, and on this basis to achieve comprehensive evaluation of the operation status. Firstly, according to the main concerns of both power supply and demand for distribution network operation, the index system of five-level structure is sorted out. Then, the index weighting method based on the combination of analytic hierarchy process (AHP) and entropy weight method is studied to effectively integrate subjective and objective weights. Finally, based on actual cases, the composite calculation of index scores and combination weights is carried out, and the relevant analysis is made. The example results show that the method proposed in this paper is effective and reasonable for comprehensive and accurate evaluation of distribution network operation situation.
