Fuzzy Synthetic Evaluation and Analysis for Power System State Estimation Algorithm
Sun Li · Journal of Zhengzhou University · 2011
Algorithm of state estimation is the core of power system state estimation.Many algorithms have been proposed with different advantages.Fuzzy mathematics theory is introduced to evaluate state estimation.Fuzzy synthetic evaluation model is built for state estimation,which will be used to evaluate and compare objectively those algorithms.And then the best algorithm of state estimation will be found for a specific power system.In different power systems,the proposed evaluation system is used to evaluate some common algorithms of state estimation and found the best one.The calculation results show that the evaluation system is correct and can quantify the qualitative-analysis of algorithm evaluation.It can give effective reference to choose algorithm for actual power system.
