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.
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.
When the grid price is in the valley period, such as 15:00–18:00, the energy storage system chooses not to discharge regardless of the power shortage. Thereafter, the energy storage system initiates the discharging mechanism when the grid price is in the peak period starting period of 18:00.
Subsequently, a method involving a bilevel optimization model was adopted: by replacing the original energy storage capacity at each end of the source, grid, and load with the FESPS, the energy storage capacity was fully released.
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.
