Based on probabilistic production simulation, a novel calculation approach for peak-load regulation capacity was established in Jiang et al. (2017), which is still effective for peak-regulation capacity planning when some information of renewable energy and loads is absent.
What is peak-regulation capability of a power grid?
Principle of the evaluation method The peak-regulation capability of a power grid refers to the ability of power supply balancing with power load, especially in the peak load and valley load periods. Specifically, the adjustment range of power supply in one day should be high enough to reach the peak load and low enough to reach the valley load.

Midday to evening is the peak load period, where BESS is used for discharging to relieve the pressure of peak power consumption. The interval of PSVF applications can be used for FR. The overall regulated power has a maximum unidirectional demand of around 45 MW and a short duration, while most power demand falls within 20 MW.
