Comprehensive evaluation of operation state of energy storage charging station
With the strong support of national policies for new energy, the number of electric vehicles has been growing rapidly in recent years, and energy storage charging stations have emerged. In order to guide the operation management and state monitoring of the energy storage and charging station, this paper puts forward a multi index evaluation system of the operation state of the energy storage and charging station. The evaluation indexes include efficiency, reliability, output and energy storage, and 15 secondary indexes are set. According to the influence of the operation state of the energy storage charging station on the distribution network, the reliability of the charging pile, the service life of the energy storage battery and the safety of the electric vehicle power battery, the importance of the evaluation indexes is established, and the weight values of each index are determined according to the AHP entropy weight correction method, and the weight matrix is established. The final evaluation method is formed by combining it with the index score based on the fuzzy scoring theory. Finally, the validity of the evaluation method is verified based on the operation data of a storage charging station.
