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.
To balance the peak–valley (off-peak) difference of the load in the system, the power system peak load regulation is utilized through adjustment of the output power and operating states of power generator units in both peak and off-peak hours.
To address power fluctuations in each frequency band, the power capacity of each Energy Storage Device (ESD) is determined based on the absolute peak value of the power Pb-i in each frequency band, referred to as \ (\left| {P_ {b - i} } \right|max\) (either the maximum value \ (P_ {b - i - \max }\) or the minimum value \ (P_ {b - i - \min }\)).
The intrinsic capacity of the thermal units in the system peak load regulation is studied on the generation side. An improved linear UC model considering startup and shutdown trajectories of thermal power units is embedded with the peak load regulation compensation rules.
Capacity configuration optimization model of industrial load and energy storage system Considering the tough environment, two ESSs are compared to analysis their annual economic profitability.
