摘要：

In this paper, an active distribution system state estimation (ADSSE) method with considering the characteristics of distributed generations (DGs) is proposed, in which the running and controllable characteristics of DGs are discussed and analyzed. The mathematical model which can reflect realtime monitoring of the running and controlling state of DGs is established, and their running state variables and controllable parameters are introduced into ADSSE based on weighted least squares (WLS), then the state estimation model of the proposed ADSSE method is obtained, which can accurately estimate the running state variables and controllable parameters of DGs. Finally, it follows from the simulation results that the proposed ADSSE method is successful and effective.
