AHP based Evaluation of Energy Storage System

Currently, there are few classification evaluation methods for specific application scenarios of battery energy storage systems (BESS). In this paper, an evaluation method of distributed BESS based on analytic hierarchy process (AHP) is proposed. Firstly, a variety of BESS evaluation indexes in three aspects of economy, reliability and functionality are proposed. Secondly, this method selects evaluation indexes matching with typical application scenarios and establishes evaluation models to evaluate the typical scenarios in which BESS provide voltage support, standby power supply, peak cutting, and valley filling. The weights of each index in different application scenarios are divided by AHP. All factors are integrated so that the BESS can be evaluated accurately. Finally, the feasibility and practicability of this evaluation method are proved by showing a concrete application example.
