Evaluation of grid energy storage system based on AHP-PROMETHEE-GAIA

Abstract

In the grid, the application of energy storage technology plays a crucial role, so the evaluation of energy storage ways has become a more concerned problem, and the choice of energy storage ways is a multi-rule-based decision. A AHP-PROMETHEE-GAIA method based on the analysis of the characteristics of the existing energy storage ways is presented. Taking the factors, such as technology maturity, cost, life, efficiency, response speed and environment as assessment criterion, a comprehensive evaluation for the existing energy storage ways is made. The Analytic Hierarchy Process (AHP) is used to determine the hierarchical structure and weight of evaluation index, the Preference Ranking Organization Methods for Enrichment Evaluations (PROMETHEE) is used to sort all the energy storage ways and the Geometrical Analysis for Interactive Assistance (GAIA) is used to analyze the sensitivity. And the effects of the result as the changing rule-weights are analyzed and evaluated. Through the evaluation, this method is proven to have actual reference to selecting energy storage way.
