Technical FAQs 4

What is peak shaving in power system?

In the power system, the load usually shows “peak” and “valley” differences. It refers to the fact that the load is higher during certain times of the day and lower during other times of the day. In order to meet the peak demand, the power system needs to carry out peak-shaving.

How to improve peak-shaving capacity of Ningxia power system?

Utilizing the deep regulation capability of thermal power units and energy storage for peak-shaving and valley filling is an important means to enhance the peak-shaving capacity of the Ningxia power system. There are existing references on the economic optimization of operation using energy storage and thermal power units.

Will energy storage become the second largest peak-shaving resource?

By 2030, the scale of energy storage will expand rapidly, becoming the second largest peak-shaving resource in addition to thermal power units, as shown in Table 1. With the abundance of peak-shaving resources and the development of power auxiliary service market, the optimization of peak-shaving cost of power system has become an urgent problem.

Can battery energy storage power station solve the peak shaving problem?

When building a battery energy storage power station to solve the peak shaving problem caused by the large-scale nuclear power construction, the safe operation of nuclear power and the comprehensive economic benefits between nuclear power and battery energy storage power station should be fully analyzed.
