6 FAQs about [Deepen energy storage and peak load regulation]

Do thermal power units provide deep peak regulation?

Specifically, first, the flexibility requirement of renewable integration is quantified, and the operating characteristics of thermal power units providing deep peak regulation are modeled. On this basis, a capacity optimization for BES is proposed considering peak regulation characteristics of thermal power units.

Do I need to charge the energy storage system for peak shaving?

The dispatching department calls it for free. When the output of thermal power unit is between (1 − k) Pthe and 0.5 Pthe, the thermal power unit has the ability for peak shaving. At this time, there is no need to charge the energy storage system for peak shaving. To avoid deep discharge in energy storage system, SOCmin is set to 20%.

Is there a trade-off between energy storage and peak regulation?

In the meantime, the trade-off between deploying energy storage and leveraging the deep peak regulation capacity of existing thermal generators remains to be explored.

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 the peak load and Valley load of energy storage system?

The load data was extracted from the historical data of typical daily load, as shown in Table 3. The peak load and valley load are 3475.94 MW and 2595.70 MW, respectively. The parameters of the energy storage system are shown in Table 2 .

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).
