Research on Distributed Energy Storage Operation Modes and Multi-dimensional Benefit Evaluation

With the widespread application of renewable energy and the continuous development of energy storage technologies, distributed energy storage systems are demonstrating significant application potential in distribution network. However, the evaluation of energy storage applications has mostly been limited to singular aspects such as mitigating fluctuations in renewable energy output and peak shaving valley filling, with relatively few studies focusing on the value evaluation of distributed energy storage on the user side of substation areas. To address this, this paper proposes a multi-dimensional benefit evaluation method to configuring energy storage, constructs a refined model to represent the costs of energy storage systems, and evaluates the value and benefits of distributed energy storage using 17 substation areas in a certain city as an example. The evaluation results demonstrate the effectiveness of the proposed approach.
