Integrated Heating Load and Storage Control for Curtailed Wind Power Consumption in China’s Power Market
Publication: Journal of Energy Engineering
Volume 143, Issue 5
Abstract
For heavily curtailed wind power caused by the coexistence of large-scale wind power and high-penetration combined heat and power (CHP) units, especially during the winter heating period in northern China, the flexible operation of CHP units with the introduction of thermal energy storage (TES) and heating load flexibility is very helpful for reducing wind power curtailment in northern China. Therefore, based on the construction of a two-stage trading mode in the day-ahead market, which consists of the conventional energy market and peak regulation market, a three-level optimization method is proposed for integrating heating loads and storage control through the coordinated operation of CHP units and TES devices and heating load management. Thus, the operation mode of CHP units can be optimized to supply peak regulation capacity for curtailed wind power under a certain agreed peak regulation price. Finally, the typical influence factors, such as the capacity of TES devices, the agreed peak regulation price, and the different operation modes, will be discussed to demonstrate the resulting economic benefit and curtailed wind power consumption.
