Abstract:A deep peak load regulation compensation mechanism of thermal power units is presented to encourage the units to actively participate in peak load regulation and improve their peaking capability. The compensation mechanism consists of two sections. In the first section, the method of dividing basic peak load regulation and deep peak load regulation is determined base on the approved peaking rate of thermal power units. In the second section, the peaking compensation model of thermal power units incorporating the change of peaking demand and the difference of peaking capability is given. In the model, the peaking demand of power grid is used to correct the peaking compensation standard, the peaking capability of thermal power unit is used to correct the peaking compensation cost. The proposed compensation mechanism is impartial for all thermal power units and is effective for units to actively participate in the peak load regulation and to improve their peaking capability. A case study demonstrates the rationality of the compensation mechanism.
