6 Frequently Asked Questions about “Wind power generation energy storage peak load regulation”
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.
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.
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.
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.
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 the objective function for peak-regulation capacity?
For optimization models, an additional objective function for the peak-regulation capacity was established by the robust unit commitment model to meet the peak-regulation demands of power grid with wind power integration (Yuan et al., 2019).
