An evaluation method with multi-technical indicators for capacity configuration scheme of the energy storage system at user side basing on game topsis

Effective evaluation is conducive to optimising the reasonable allocation of user energy storage and promoting the healthy development of the energy storage industry. Aiming at the problems of low attention, imperfect evaluation system and insufficient quantification of traditional evaluation methods, an evaluation method based on combined weighting and improved TOPSIS method for the capacity allocation of user energy storage system is proposed. According to the operation process and characteristics, combined with the trend and distance indicators, a comprehensive evaluation system covering performance, economy and society is constructed. The G1 method and independent weight method are used to calculate the subjective weight and objective weight of the evaluation index, and the improved game theory method is used to calculate the comprehensive weight of the evaluation index. Taking the energy storage system of commercial users as an example, the effectiveness and practicability of the proposed method are verified.
