During the three time periods of 03:00–08:00, 15:00–17:00, and 21:00–24:00, the loads are supplied by the renewable energy, and the excess renewable energy is stored in the FESPS or/and transferred to the other buses. Table 1. Energy storage power station.
Through the incorporation of various aforementioned perspectives, the proposed system can be appropriately adapted to new power systems for a myriad of new energy sources in the future. Table 2. Comparative analysis of energy storage power stations with different structural types. storage mechanism; ensures privacy protection.
In addition, by leveraging the scaling benefits of power stations, the investment cost per unit of energy storage can be reduced to a value lower than that of the user’s investment for the distributed energy storage system, thereby reducing the total construction cost of energy storage power stations and shortening the investment payback period.
The operation process of power flow regulation and shared energy storage of bus 1 after obtaining the solution to the bilevel optimization operation model is depicted in Fig. 9. During the periods of 01:00–05:00 and 23:00–24:00, the load is jointly supplied by the power flow transfer and the superior power grid.
For power grid enterprises, multi-point centralized medium and large-scale energy storage stations will be conducive to the reinforcement of the distribution network and the sustainable consumption of renewable energy.
Firstly, this paper proposes the concept of a flexible energy storage power station (FESPS) on the basis of an energy-sharing concept, which offers the dual functions of power flow regulation and energy storage. Moreover, the real-time application scenarios, operation, and implementation process for the FESPS have been analyzed herein.
