Beijing, China In the multi-station integration scenario, energy storage power stations need to be used efficiently to improve the economics of the project. In this paper, the life model of the energy storage power station, the load model of the edge data center and charging station, and the energy storage transaction model are constructed.
As a flexible power resource, energy storage stations can store and release electrical energy according to the need, thereby balancing load and supply in the power system and enhancing its reliability and cost-effectiveness .
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.
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.
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.
