Abstract: The optimal configuration of battery energy storage system is key to the designing of a microgrid. In this paper, a optimal configuration method of energy storage in grid-connected microgrid is proposed. Firstly, the two-layer decision model to allocate the capacity of storage is established.
1. An energy storage configuration and scheduling strategy for microgrid with consideration of grid-forming capability is proposed. The objective function incorporates both the investment and operational costs of energy storage. Constraints related to inertia support and reserved power are also established. 2.
The results demonstrate that the proposed strategy can economically and effectively meet the power and energy balance of the independent microgrid and the electricity demands of high-energy-consuming loads, while promoting the improvement of new energy accommodation capacity.
Optimizing the configuration and scheduling of grid-forming energy storage is critical to ensure the stable and efficient operation of the microgrid. Therefore, this paper incorporates both the construction and operational costs of energy storage into the objective function.
Through case studies (Case 1 to Case 4), the SESS configuration significantly improves the renewable energy consumption rate from 73.05% to 99.93%. This indicates that shared energy storage effectively promotes renewable energy utilization while reducing microgrid operating costs.
This study introduces a novel optimization approach for the shared energy storage configuration of multiple microgrids, considering both battery lifespan and the economic utilization of
