Due to the decreased demand for energy storage in the microgrid cluster, with the budget unchanged, the microgrid cluster increases the investment in self-built energy storage. It reduces the investment in leased energy storage to reduce the lifecycle cost of SES.
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.
Subsequently, a robust optimization model is formulated for configuring shared energy storage within a microgrid cluster, incorporating considerations of inter-microgrid energy sharing, seasonal variations in net load curves, and associated volatility.
Among them, the power and capacity configurations of self-built energy storage show a downward trend; the power and capacity configurations of leased energy storage keep increasing. This indicates that the microgrid cluster system reduces operational risks by increasing SES power and capacity configurations.
The results indicated that, compared to individual energy storage, the battery capacity for storage in the microgrid cluster was reduced by 75.94 %. Most of the above studies optimize the capacity of SES and the system operation strategy using either self-built or leased energy storage.
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.
