4 FAQs about [Nuclear power storage peak load regulation]

How to regulate peak demand of nuclear power?

As the use of clean energy such as wind power and nuclear power has been increasing, the base load operation of nuclear power units usually means huge pressure for local power systems in regulating peak demand. In order to use more regulation resources, a multi-area joint optimization model involving peak regulating of nuclear power is proposed.

What is the peak load regulating mode of the nuclear power system?

In Mode 2, the nuclear power system runs in “12-3-6-3” load tracking mode for peak load regulating. The load valley output period is from 3:00 to 9:00, the peak load regulating depth is 50%, and the power of peak shaving is 2000 MW. The valley-to-peak difference is reduced from 9648 MW to 7648 MW, which is reduced by 20.7%.

Why is the demand for nuclear power plants to implement peak shaving?

So far, the nuclear power has been expanding its presence in the regional power grid, and China’s nuclear power units in operation usually operate at full power as base load, which creates great challenge for the regional power system in peak load regulation. Therefore, the demand for nuclear power plants to implement peak shaving is increasing.

Is peak regulating of wind power better than tie-line power optimization?

In general, it is observed from the wind curtailment that both peak regulating of nuclear power and tie-line power optimization can better contain the negative peak regulating of wind power output.
