Evaluation of Energy Storage Station Based on the Optimal Weighting Method

The energy storage station is playing an increasingly important role in supporting new power systems. How to scientifically and effectively evaluate the application effect of energy storage stations is an urgent problem to be solved. In this study, a multi-indicator evaluation model for energy storage stations is established. An improved fuzzy comprehensive assessment (FCA) with optimal weight is applied to actual energy storage stations. Using the energy storage station monitoring platform, comprehensive evaluation scores of demonstrated energy storage stations are obtained. The support effect of energy storage stations on the power grid is evaluated from three aspects: performance, operational reliability, and energy efficiency. The higher the evaluation score, the stronger the energy storage regulation ability, and the more significant the active support to the power grid.
