Research on User Loss Contribution Calculation of High-Loss Distribution Area Based on Transfer Entropy

In the line loss management of low voltage distribution table area, it is difficult for power company to manage line loss because of the abnormal behavior of users and the behavior of stealing power. In this paper, the contribution of user loss is calculated by transfer entropy algorithm for users in high-loss area. Copula entropy is used for nonparametric estimation to improve computational performance. After ranking the loss contribution degree of users, targeted measures should be taken to rectify the loss contribution degree of users of different degrees. This method can effectively improve the efficiency of line loss management and reduce the overall line loss rate of the distribution area.
