6 FAQs about [New energy participates in peak load regulation]
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.
Do thermal power units participate in peak regulation auxiliary services?
Owing to China’s energy structure, thermal power accounts for nearly half of the country’s installed power generation capacity. Although the willingness of thermal power units to participate in peak regulation auxiliary services is low, we propose a peak regulation cost compensation and capacity-proportional allocation mechanism.
What is deep peak regulation of thermal power plants?
Therefore, deep peak regulation (DPR) of thermal power plants remains one of the main peak regulation methods for the source side in China. The lower reserve capacity of thermal power plants is used to provide peak regulation power generation rights for renewable energy sources such as wind and solar energy.
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).
How to reduce peak regulation pressure of thermal power units?
In order to reduce the peak regulation pressure of thermal power units and maximize the use of resources such as wind, solar, water storage and DR to participate in peak regulation auxiliary services, the minimum fluctuation of thermal power output is taken as the objective function, as shown in Eq. 19.
How effective is peak-load regulation capacity planning?
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.
