Energy storage site selection evaluation method and system

Abstract

The invention discloses an energy storage site selection method, which comprises the following steps of: selecting an energy storage site, wherein an aquifer exists under the energy storage site; determining a plurality of primary indexes and secondary indexes of the energy storage site, and determining weight value information corresponding to each primary index and each secondary index by utilizing a chromatography method, and giving score information to each first-level index and each second-level index, obtaining a comprehensive evaluation value of the energy storage site by combining the weight value information of each first-level index and each second-level index and utilizing a multi-factor comprehensive evaluation method, and judging the suitability of the energy storage site according to the comprehensive evaluation value. The invention further discloses an energy storage site selection system, the target salt water aquifer site selection evaluation method for aquifer compressed air energy storage is established for the first time, important factors needing to be considered are listed, reasonable thresholds of different indexes are defined, and the important site selection link of the system from theory to application is filled.

Description

Technical field [0001] The present invention relates to the intersection of hydrological geological surveys and new energy storage, and in particular, there is a method and system for energy storage siter. Background technique [0002] The use of renewable energy in the wind and light is the inevitable choice for the transformation of world energy structures and reducing the total carbon dioxide. The total amount of wind / photovoltaic power generation at home and abroad increased significantly in recent years. However, this new energy power generation has intermittent and randomness, and the power system is insufficient. It is difficult to adapt to large-scale grid-connected requirements, abandonment, abandonment, and new energy power supply safety and stability is to restrict new energy efficient and stable utilization. key. [0003] Large-scale energy storage technology is a key to the internationally recognized resolution of intermittent renewable energy such as wind energy, ...

AI Technical Summary

Problems solved by technology

[0004] The existing site selection method for energy storage sites only considers the thermal physical process and does not fully consider the geological conditions, and the same site selection method is used for energy storage sites with and without aquifers, and it is impossible to distinguish the location of the aquifer. Affected, there will be a large error in site selection
