According to the generator output curve and energy storage output curve, the peak regulating effect of energy storage after parameter optimization is better than that without parameter optimization.
On this basis, an optimal energy storage allocation model in a thermal power plant is proposed, which aims to maximize the total economic profits obtained from peak regulation and renewable energy utilization in the system simultaneously, while considering the operational constraints of energy storage and generation units.
At present, the research on the participation of energy storage system in grid-assisted peak shaving service is also deepening gradually [4, 6, 7, 8, 9, 10]. The effectiveness of the proposed methodology is examined based on a real-world regional power system in northeast China and the obtained results verify the effectiveness of our approach.
The plan specified development goals for new energy storage in China, by 2025, new energy storage technologies will step into a large-scale development period and meet the conditions for large-scale commercial applications.
The reverse peak regulation characteristics of new energy power generation increase the peak difference to the valley of the power grid, which makes the stable operation of the power grid difficult , . In order to mitigate the above contradiction and reduce the peak–valley difference of power grid, peak regulation is needed.
The connection of energy storage devices to the power grid can not only effectively utilize the power equipment, reduce the power supply cost, but also promote the application of new energy, improve the stability of the system operation, reduce the peak–valley difference of the power grid, and play an important role in the power system.
