Distribution Network Operating State Diagnosis Method Based on Uncertainty Propagation Theory

In order to overcome the adverse impact of the measurement error of the watt-hour meter on the accuracy of the state evaluation of the distribution network, this paper proposes a method of distribution network operating state diagnosis based on the uncertainty propagation theory. Firstly, the adversarial generation network is used to complete the measurement data of watt-hour meter. Then, the evaluation index system of distribution network operation status is constructed. Then, the evaluation index system of distribution network operation status is constructed. Then, we measure the uncertainty and analyze the influence of the uncertainty on the evaluation index system. Finally, the method of Delphi CRITIC is used to evaluate the running state of distribution network. The method in this paper is tested in the example analysis, and the results show that the measurement uncertainty will greatly affect the evaluation index results of the distribution network, thus proving the effectiveness of the method in this paper.
