摘要：the reliable state awareness of modern distribution system relies on advanced measurement system, well-adapted calculation method as well as a better understanding of load and embedded power source. State estimator, as the most important tool to achieve real-time state awareness must take load model into consideration. In this paper, the ERL (Exponential Recovery Load) model is utilized to grasp the dynamic property during the disturbance periods. The proposed SE procedure is detailed in this paper and a simulation case with IEEE-33-bus system is conducted to verify the effectiveness. © 2018 IEEE.
