Energy storage grid side peak load regulation application ppt

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 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.

Is the proposed method practical for peak-regulation evaluation of power grid?

(1) The proposed method is practical for peak-regulation evaluation of power grid. On one hand, the proposed method features high efficiency. It only takes a few seconds to complete all computations and give the visual results for a practical power grid.

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.

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.

Can nuclear power units participate in load following of power grids?

In some countries, such as France and America, nuclear power units have been allowed to participate in load following of power grids. Considering operation security, nuclear power units in China operate at rated capacity smoothly in most circumstances and scarcely provide peak-regulation service to power grids.
