It may lead to establish novel peak-regulation services in future Chinese power grid. Moreover, it is worthy to study the modification method for the derived unit commitment results, which can further improve the accuracy of the proposed evaluation method.
Principle of the evaluation method The peak-regulation capability of a power grid refers to the ability of power supply balancing with power load, especially in the peak load and valley load periods. Specifically, the adjustment range of power supply in one day should be high enough to reach the peak load and low enough to reach the valley load.
Also, the peak-regulation capability determines the renewable energy consumption and power loads of cities by mitigating power output fluctuation in the regulation process of power grid.
Considering operation security, nuclear power units in China operate at rated capacity smoothly in most circumstances and scarcely provide peak-regulation service to power grids. In this paper, nuclear power is assumed to have no peak-regulation capacity.
In this paper, nuclear power is assumed to have no peak-regulation capacity. For renewable energy, the Renewable Energy Act of People’s Republic of China stipulates that renewable energy generation can be scheduled in priority during the power grid operation.
For example, Shanghai grid has organized virtual power plants to participant in the demand response market. The total clearing capacity is 151.5 MW. It effectively supports the peak-regulation of Shanghai grid.
