Abstract:

The energy storage technology roadmap is diverse, and different types of energy storage have their application prospects. The selection of energy storage is a key issue in engineering applications. However, the selection of energy storage requires comprehensive consideration of factors such as economics and safety, making it a complex multi-objective decision-making problem. A hybrid energy storage selection evaluation system is proposed that combines the analytic hierarchy process (AHP) and technique for order preference by similarity to ideal solution (TOPSIS) with a fuzzy comprehensive analysis method. First, the judgment matrix of the evaluation system is established, and then the indicator weights undergo diagonalization and multiplication with the standardized matrix to yield the weighted judgment matrix to obtain the proximity vector. The membership assessment results of energy storage types are obtained by multiplying the weighted judgment matrix with the correlation matrix of the fuzzy comprehensive analysis method. Data in grade I indicates the energy storage system is at its optimum level, grade II follows as the next tier, and so forth in descending order. Thus, by employing TOPSIS, a more objective weight vector can be obtained, mitigating the subjectivity inherent in the AHP method. Taking seven types of energy storage, such as lithium-ion batteries, sodium-sulfur batteries, and lead-acid batteries, applied to peak load shaving, grid supply, and voltage quality improvement scenarios as examples, a comparative analysis is conducted with existing energy storage selection methodologies, highlighting the innovative nature of this evaluation framework. The effectiveness of the proposed evaluation system and selection method is verified.
