Balancing multi-prosumer energy trading

The adoption of distributed energy resources (DERs), including distributed generation units, renewable energy sources, and energy storage facilities, has been on the rise. This trend offers consumers greater freedom in selecting energy sources, mitigating price fluctuations, and opportunities for energy trading and sharing. However, motivating the shared energy storage owners to interact cooperatively and ensure fair distribution of gains remains a challenge.

We proposed a novel energy storage sharing framework that allows prosumers to share the capacity and trade stored energy with other prosumers. This framework aims to maximize the economic benefits of the prosumers by providing them with sufficient freedom in capacity sharing and energy trading. We also developed a cooperative game-based operational strategy, known as the Balanced Sharing Strategy (BSS), to minimize costs and regulate energy trading in the proposed energy storage sharing framework. 

The proposed Balanced Sharing Strategy (BSS) for energy storage sharing can achieve a balance between efficiency and fairness. It maximizes cost savings for each prosumer under a fair mechanism for stored energy trading. We also showed that there is a trade-off between fairness improvement and computational efficiency loss.
