Analysis of Cross-territory Shared Energy Storage Operation Mode

The accessibility of user-side renewable energy equipment and shared energy storage raises the importance of promoting local renewable energy consumption and minimizing the cost of energy storage. Aiming at the problem of sharing electric energy and energy storage resources across stations, the research manuscript presents a cross-station shared energy storage operation model. First, the operator, leading the way, determines intra-regional tariffs based on the supply-demand balance in each area. Secondly, users, as followers, regulate their electricity usage and likelihood of choosing a region based on intra-regional tariffs and transmission costs. While reducing the difference between the peak and valley of the system net load, the energy storage utilization rate is improved, and a win-win situation between operators, users and the power grid is achieved.
