Abstract: To solve the fuzziness of algorithm evaluation, fuzzy mathematics theory is proposed to evaluate synthetically algorithms of bad-data detection and identification. And then the best algorithm of state estimation will be found for specific power system. In different system configurations, the proposed evaluation system is used to evaluate four algorithms of bad-data detection and identification, and then the characters of the four algorithms can be found. Practical effect proves that the evaluation system is effective and can quantify the qualitative-analysis of algorithm evaluation. It can give effective reference to choose algorithm for actual power system.
