What is the difference between deep peak regulation and normal peak regulation?
It can be seen that at the phase of deep peak regulation, as the output of units decreases, the cost of thermal power unit continues to increase, which is due to the increased cost of oil input and equipment wear cost. While at the phase of normal peak regulation, the operation cost increases as the power output increases.
How does peak regulation affect the operating state of thermal power units?
