A corresponding peak load regulation model is proposed. On the generation side, studies on peak load regulation mainly focus on new construction, for example, pumped-hydro energy storage stations, gas-fired power units, and energy storage facilities .
The power system peak load regulation is conducted by adjusting the output power and operating states of the power generating units in both peak and off-peak hours.
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.
An integrated optimal scheduling model for power system peak load regulation with a suitable rolling optimization strategy is proposed. A real prefecture-level urban power system in southwest China and its modified test systems are used to test and verify the validity and effectiveness of the proposed methodology.
With the integration of renewable energy sources, thermal generators must operate in an inefficient mode, or even startup and shutdown frequently to regulate the grid peak load . The peak load regulation problem causes challenges to the power system, and countermeasures are studied on the demand side and the generation side.
