考虑电网调峰的热电联产热负荷动态调度模型

我国北方地区有丰富的风光可再生资源，冬季热电联产机组为满足热负荷需求而限制了其调峰能力，在一定程度上造成了风光与热电的结构性矛盾。针对上述问题，提出以多个机组共同满足热负荷为前提，通过构建考虑电网调峰的热电机组群热负荷动态调度模型，实现对不同热电性能机组的调峰潜力挖掘。仿真算例表明，如果机组群内存在较为明显的热电关系个体差异，热负荷动态调度可以较为明显地提升机组群的整体调峰性能，有效增加风光清洁能源消纳。

Cogeneration unit dynamic scheduling model considering peak-load regulation ability

Northern China has rich wind power and photovoltaic renewable resources. To meet the load demand, heat cogeneration units limit its peak load regulation capacity in winter, to a certain extent, resulting in structural problems of wind-solar power and thermo electric power. To solve those problems, this paper takes a plurality of units together to ensure the supply of heat load as the premise, by building a thermal load dynamic scheduling model of thermoelectric unit group considering power network peak regulation, to achieve the peak regulation potential excavation of different thermoelectric properties units. Simulation examples show, if the unit group exists obvious thermoelectric relationship individual differences, the thermal load dynamic scheduling can improve the overall peak regulation performance of unit group more significantly, and increase solar wind power consumption effectively.
