Research on Site Selection of Slope Gravity Energy Storage System Based on Analytic Hierarchy Process

As a new type of energy storage, slope gravity energy storage (SGESS) has an important application prospect in the future development of new energy. In order to select the best construction site of SGESS to ensure the smooth construction and efficient operation of the system, 11 evaluation indexes including geographical, economic and environmental factors were selected to establish its site selection evaluation system. The weights of each evaluation index are quantified by the analytic hierarchy process. Based on the proposed evaluation system, three alternative sites in a region of Guizhou Province were analyzed. The results show that geographical, economic and environmental factors have a certain correlation in site selection evaluation, and the relationship between all factors should be balanced comprehensively to find the best site selection scheme. The research results provide a certain reference value for the site selection of SGESS.
