What time does the energy storage power station operate?
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.
Why should power grid enterprises use multi-point centralized energy storage stations?
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.
How can energy storage system reduce the cost of a transformer?
Concurrently, the energy storage system can be discharged at the peak of power consumption, thereby reducing the demand for peak power supply from the power grid, which in turn reduces the required capacity of the distribution transformer; thus, the investment cost for the transformer is minimized.
When does the energy storage system choose not to discharge?
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.
