Relationship between the national development energy storage company and the peak load regulation company

How does a power system meet peak load?

Sequences of power resources to meet peak load. The DR represented by the air-conditioning load on the demand side meets the peak demand very quickly. In addition, it requires no upfront investment for the power system, which is initially set to facilitate work and life.

What is the power and capacity of Es peaking demand?

Taking the 49.5% RE penetration system as an example, the power and capacity of the ES peaking demand at a 90% confidence level are 1358 MW and 4122 MWh, respectively, while the power and capacity of the ES frequency regulation demand are 478 MW and 47 MWh, respectively.

Does penetration rate affect energy storage demand power and capacity?

Energy storage demand power and capacity at 90% confidence level. As shown in Fig. 11, the fitted curves corresponding to the four different penetration rates of RE all show that the higher the penetration rate the more to the right the scenario fitting curve is.

Do independent energy storage power stations lease capacity?

Independent energy storage stations lease capacity to wind power, PV, and other new energy stations. Capacity leasing is a stable source of income for owners of independent energy storage power stations. The capacity leased can be seen as energy storage capacity built for new energy projects.

What is the implementation plan for the development of new energy storage?

In January 2022, the National Development and Reform Commission and the National Energy Administration jointly issued the Implementation Plan for the Development of New Energy Storage during the 14th Five-Year Plan Period, emphasizing the fundamental role of new energy storage technologies in a new power system.

What is the minimum charge and discharge time of energy storage system?

The minimum charge and discharge time is set to 0.5 h, and the power gap duration is 0–180 h to ensure the ability of the energy storage system to guarantee power sufficiency. The capacity of the energy storage system does not change, which is equivalent to the initial investment of the other strategies.
