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 peak–valley load difference (Jin et al., 2020).

What is peak regulation & power system flexibility?

The peak regulation (PR) service provided by generation plants are the major source of power system flexibility. PR means that the plants changing its’ generation to match the power demand. As the main power resource in most countries and regions, including China, coal-fired power plants are the most important source of power system flexibility.

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.
