Conclusion This paper presented an optimal scheduling model for power system peak load regulation considering the short-time startup and shutdown operations of a thermal power unit. As the main resource on the generation side, the intrinsic capacity of the thermal units in the system peak load regulation was studied in this paper.
The proposed method was verified in a real prefecture-level urban power system in southwest China, and its modified test systems. The case studies demonstrated the intrinsic capacity of the thermal units in the system peak load regulation.
To the best of our knowledge, this study is the first to integrate different modes’ peak load regulation cost of thermal units into the optimal scheduling model. The proposed method was verified in a real prefecture-level urban power system in southwest China, and its modified test systems.
For power units participating in deeper peak load regulation, the compensated electricity quantities are determined by regulation durations and the difference between the actual load rate and the lower bound of the basic regulation range. The compensation standards are under a set of piecewise progressive rules, as displayed in Table 3.
