Optimal Peak Regulation Strategy of Virtual and
The fast peak regulation characteristics of the virtual power plant means that the virtual power plant has a faster second-level adjustment response capability than the thermal power plant, and it can also jointly peak
Source-load cooperative multi-modal peak regulation
The lower reserve capacity of thermal power plants is used to provide peak regulation power generation rights for renewable energy sources such as wind and solar energy. The load side adopts demand response (DR)
Optimal scheduling for power system peak load regulation considering
The output of wind power generators could vary stochastically between zero and the rated capacity. The output could be low when the load demand is in peak hours, while it

606 FAN ET AL. FIGURE 1 Schematic diagram of thermal power unit peaking process. where H is the planning period, δ is the discount rate; c g is the flexibility transformation cost per unit
Multi-angle Economic Analysis on Deep Peak Regulation of Thermal Power
The deep peak regulation of thermal power units increases the utilization of wind power, however, it also leads to high economic costs for the operation of thermal plants.
IET Renewable Power Generation
Reference established a three-layer robust planning model for energy storage system adapted to the uncertainty of wind power investment and thermal power unit retirement to balance the investment cost and operation
Comparative Analysis of Peak Regulation Economy of Thermal
Wind and solar power generation are highly uncertain, intermittent, and random, leading to frequent deep peaking of coal-fired thermal power units, and the resulting coal consumption
Optimal operation strategy of peak regulation combined thermal power
Therefore, a concentrated solar power (CSP) plant equipped with an electric heater (EH) is implemented to join the peak regulation, and the joint peak regulation strategy
6 FAQs about [Wind power generation and thermal power peak regulation]
What is deep peak regulation of thermal power plants?
Therefore, deep peak regulation (DPR) of thermal power plants remains one of the main peak regulation methods for the source side in China. The lower reserve capacity of thermal power plants is used to provide peak regulation power generation rights for renewable energy sources such as wind and solar energy.
What causes peak-regulation problems of wind power integrated power systems?
The peak-regulation problems of wind power integrated power systems were reviewed in Yuan et al. (2011). Moreover, some measurements for reducing the peak load were studied. Administrative factors and market barriers were regarded as the main causes of renewable energy curtailment.
Are thermal power units a source of peak regulation?
As conventional power generation units, e.g., thermal power units (TPU) and hydro units, are relatively more flexible in terms of regulation capacity compared with the renewable energy generation, they are the fundamental sources of peak regulation (Gao et al., 2020; Guan et al., 2022).
Does wind power need Peak-Valley regulation and frequency control?
This chapter introduces wind power's demand for peak-valley regulation and frequency control and suggests several measures such as utilization of thermal power generator, energy storage, and demand response. 6.1. Peak-Valley Regulation and Frequency Control Measures Adopted by Large-Scale Wind Power Bases
Why does peak load regulation cause wind power curtailment?
While the core reason why peak load regulation causes wind power curtailment is the inflexibility of the power source structure, the core reason why external transmission causes wind power curtailment is the inflexibility of power grids.
What is the difference between photovoltaic peak regulation and wind power profit?
The wind power profit and photovoltaic peak regulation are composed of the profit from electricity sales, the allocation cost, and the penalty for abandoning wind and light. The thermal power peak regulation profit is composed of compensation, allocation, and DPR costs. These are shown in Eqs. 7 – 9.
