Do coal-fired power plants need deep peak regulation?

Considering that the minimum generation limit of coal-fired plants is much higher than that of most generation technologies, and coal-fired power plants cannot be frequently started up and shut down, thus deep peak regulation (DPR) is an essential service provided by coal-fired power plants to support renewable energy integration.

What is the peaking capacity of coal-fired power plants?

It was asked that the load peaking capacity of newly built coal-fired power plants should not be less than 35–40% of the rated power load, in addition to burning inferior coal. These documents have played a formative role in power grid peak regulation for decades.

Are coal-fired power units limiting peak shaving capacity?

The key factors limiting coal-fired power unit peak shaving adjustable capacities and units running into problems caused by low-load peak shaving operation were researched and analyzed in combination with the performance test reports of each unit offered by the Electric Power Research Institutes. Table 1.

What is peaking capacity of a power grid?

Generally, its peaking capacity is about 50% of the rated capacity. However, there is also some distinction in the different regional power grids. Both deeper peak regulation and start–stop peak regulation are called paid peak-regulation.

Can coal-fired power plants be used for peak regulation of power Gird?

Oxygen-enriched combustion, plasma combustion and micro-oil combustion technology have been applied in coal-fired power units to improve the combustion stability at low loads. Therefore, coal-fired power plants are capable of peak regulation and will be the main power supply used for peak regulation of power gird in the future.
