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.
For the first time, the reliability of flexible DC is improved to the level of conventional DC. the world’s largest power fully controlled turn off device (4.5kv, 3000A high power IGBT). Source: 北极星风力发电网
The energy storage power station uses various battery technologies (such as lithium-ion battery, sodium sulfur battery, lead-acid battery, etc.) or other energy storage methods (such as hydraulic energy storage, thermal energy storage, compressed air energy storage, etc.) to store and release electric energy (Wang et al., 2021).
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 practical significance of the results lies in the fact that the optimization of control parameters can not only improve the overall stability of the flexible DC transmission system, but also reduce the response time and fluctuation amplitude of the power grid when it encounters unexpected events or environmental changes.
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.
