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 do energy storage power stations work?

Driven by the peak and valley arbitrage profit, the energy storage power stations discharge during the peak load period and charge during the low load period. They play the role of “cutting peak and filling valley” and realize the full utilization of energy storage resources.

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.

What is peak shaving?

Peak-shaving refers to the reasonable adjustment of power system according to the change of power load to ensure the reliability and stability of a power supply. In the power system, the load usually shows “peak” and “valley” differences.
