FAQS about How can independent energy storage participate in power peak regulation
Why is peak-regulation important in power grids?
Peak-regulation in power grids needs to follow the fluctuation of renewable energy generation in addition to the variable load demands. Moreover, the wind power curve usually shows opposite increasing trend to the load curve, which requires more peak-regulation supply to guarantee the secure operation of power grids.
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).
Does nuclear power have peak-regulation capacity?
In this paper, nuclear power is assumed to have no peak-regulation capacity. For renewable energy, the Renewable Energy Act of People’s Republic of China stipulates that renewable energy generation can be scheduled in priority during the power grid operation.
What is peak-regulation capability?
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.
Why is peak-regulation insufficiency a problem in urban power grids?
In recent years, the power load as well as the peak–valley load difference has increased greatly, causing the shortage of peak-regulation capacity in urban power grids. Furthermore, with the increasing penetration of renewable energy generation (Ahmad et al., 2021), the peak-regulation insufficiency issue becomes even more serious and complicated.
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.
