An Integrated Evaluation of Novel Energy Storage Performance Based on Multilevel Fuzzy Comprehensive Evaluation Method

In recent years, the rapid development of energy storage technology has significantly enhanced its overall performance. However, the comprehensive evaluation of energy storage system performance remains a challenge due to its complex and dynamic nature. In this paper, a novel approach is proposed based on the multilevel fuzzy comprehensive evaluation to comprehensively assess the operational performance of energy storage systems. A comprehensive evaluation index system is first established and the evaluation indexes are classified into multiple levels according to their importance and impact level. Fuzzy set theory is then applied to handle the uncertainties and vagueness involved and weights are assigned to each index. Eventually, simulation experiments are conducted to validate the effectiveness and accuracy of the proposed method.
