Abstract

The invention relates to a comprehensive efficiency evaluation method and system for a pumped storage and electrochemical energy storage power station. The method comprises the following steps: acquiring a plurality of four-level indexes of the comprehensive efficiency evaluation system for the pumped storage and electrochemical energy storage power station; classifying and calculating the plurality of fourth-level indexes to obtain second-level indexes; the secondary indexes comprise an adjusting capability index, an energy efficiency level index, an environmental protection index and an economic index; according to the second-level indexes and the fourth-level indexes, the relative close degree of the pumped storage power station and the electrochemical energy storage power station is determined through an improved CRITIC weighting method; and determining an evaluation result of the comprehensive efficiency of the pumped storage and electrochemical energy storage power station according to the relative close degree. The accuracy of the evaluation result of the comprehensive efficiency can be improved.

Description

technical field [0001] The invention relates to the field of performance evaluation of pumped storage and electrochemical energy storage power stations, in particular to a comprehensive performance evaluation method and system for pumped storage and electrochemical energy storage power stations. Background technique [0002] With the continuous advancement of the country's goal of building a new power system, pumped storage and electrochemical energy storage, as widely used energy storage power sources, play an increasingly important role in the system, but how to evaluate and select them has always been a common concern in the industry hot issues. [0003] At present, the evaluation of energy storage is mainly carried out from the following aspects. ① In terms of technology, use indicators such as response time, stabilization time, and ramp rate to measure the frequency modulation performance of pumped storage; select indicators such as response time, adjustment rate, and ...
