State Estimation in Power System by Efficient Elimination Method of Bad Data

효과적인 불량정보제거법에 의한 전력계통에서의 장웅추정에 관한 연구

This paper describes a method for the state estimation in electric power system. The state values are estimated through the weighted least square method considering the bad data. Then, the bad data are identified by using sensitivity coefficients of power system after being detected the bad data through the distribution of T. This method was applied to the model power system, and, the results of test for proposed method are given.
