6 FAQs about [Energy storage peak regulation principle]
What is the peak regulating effect of energy storage after parameter optimization?
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.
Do I need to charge the energy storage system for peak shaving?
The dispatching department calls it for free. When the output of thermal power unit is between (1ββ k) Pthe and 0.5 Pthe, the thermal power unit has the ability for peak shaving. At this time, there is no need to charge the energy storage system for peak shaving. To avoid deep discharge in energy storage system, SOCmin is set to 20%.
Can energy storage provide peak regulation service in smart grid?
Optimal Deployment of Energy Storage for Providing Peak Regulation Service in Smart Grid with Renewable Energy Sources. In: Xue, Y., Zheng, Y., Rahman, S. (eds) Proceedings of PURPLE MOUNTAIN FORUM 2019-International Forum on Smart Grid Protection and Control. PMF PMF 2019 2021. Lecture Notes in Electrical Engineering, vol 584.
What is peak regulation?
Peak-regulation refers to the planned regulation of generation to follow the load variation pattern either in peak load or valley load periods. Sufficient peak-regulation capability is necessary for the reliable and secure operation of power grid, especially in urban regions with extremely large peakβvalley load difference (Jin et al., 2020).
