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.
This article will delve into the importance and necessity of capacity configuration when energy storage stations participate in the regulation of primary frequency. Currently, there have been some studies on the capacity allocation of various types of energy storage in power grid frequency regulation and energy storage.
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.
The power is positive during energy storage charging and negative during discharging. This means the rated power of the energy storage should be capable of meeting the maximum power requirement in the T period, independent of the charging state, to achieve an active power balance.
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.
Each part of the energy storage power station contributes. The pumped storage system handles relatively slow power fluctuations. Lithium batteries allocate the power portion between high and low frequencies. The supercapacitor mainly takes on the high-frequency part where the frequency change is the fastest.
