What is a peak load regulation model?
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 peak load regulation problem causes challenges to the power system, and countermeasures are studied on the demand side and the generation side. On the demand side, demand response programs encourage consumers to reduce and/or shift their electricity usage during peak hours .
Can battery energy storage system be used for frequency and peak regulation?
Some scholars have made lots of research findings on the economic benefit evaluation of battery energy storage system (BESS) for frequency and peak regulation. Most of them are about how to configure energy storage in the new energy power plants or thermal power plants to realize joint regulation.
What is the optimal scheduling model for power system peak load regulation?
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.
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.
Can peak load regulation cost be integrated into the optimal scheduling model?
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.
