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 (1 − 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%.

Does energy storage system contribute to grid-assisted peak shaving service?

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.
