Abstract: With nuclear power generation increasing, power system peak load situation is becoming more and more serious. It is very important to study the joint generation dispatching issue of power grid for nuclear power peaking. Due to the anti peaking characteristics of wind power output, power load peak valley difference further increases, and thus it exacerbates the
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.
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).
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.
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.
The peak–valley load difference of daily load curve determines the peak-regulation demand. In recent years, the power load and the peak–valley load difference of daily load are growing significantly.
Also, the peak-regulation capability determines the renewable energy consumption and power loads of cities by mitigating power output fluctuation in the regulation process of power grid.
