A new operating status evaluation method for smart meters was proposed in this paper, which combined TOPSIS, deviation maximization and cluster analysis. First of all, we built a status influence quantity of smart meters. Then we considered that the TOPSIS method can only get the relative evaluation result and can not reflect the weight of different evaluation vector. Thus, the calculation formula of distance was improved, in order to obtain the absolute evaluation result in the TOPSIS analysis. Combining with the empowerment of maximizing deviation method, the operating status scores of smart meters were obtained. Finally, combined with the clustering method, the operating status scores of the smart meters were discretized, thus the operating status of smart meters were determined.
