摘要:
      挖掘热电联产机组的调峰能力可以有效改善中国“三北”地区的弃风问题。调峰补偿机制是激励热电联产主动参与,电网调峰的有效手段。在考虑调峰补偿的前提下,对热电联产机组参与电网调峰进行研究。首先,计及热力系统复杂供热约束的影响,建立热电联产机组的可用调峰容量和调峰成本评价模型,可以反映热电联产调峰中的供热依赖特性和时序耦合特性。然后,基于热电联产调峰成本及调峰补偿机制,提出考虑机组调峰主动性的电热协调调度方法,相较于传统的垂直一体化电热协调调度,所提出的方法可以反映热电联产在经济手段激励下主动参与电网有偿调峰的意愿。最后,通过算例分析研究了热电联产机组的可用调峰容量和调峰成本的影响因素,并验证了所提出的调度方法在调峰补偿机制下的有效性。
Abstract:
      Exploring the peak regulation ability of combined heat and power(CHP)units could improve the severe wind curtailment problem in Northern China. Peak regulation compensation is an effective way to stimulate CHP units to participate in power peak regulation initiatively. Based on the peak regulation compensation mechanism, this paper investigates the participation of CHP units in power system peak regulation. Firstly, a model for assessing the available peak regulation capacity of CHP units and the corresponding peak regulation cost is proposed by considering complicated operation constraints of the heating system. The proposed model reflects heating-dependency and temporal-coupling characteristics of CHP peak regulation. Secondly, based on peak regulation cost of CHP units as well as the peak regulation compensation mechanism, an integrated power and heat dispatch method considering peak regulation initiative of the units is proposed. Compared with the traditional vertical integration dispatch mode, the proposed method can better reflect the willingness of CHP units to participate in power system peak regulation with economic incentives. Finally, case studies are provided to analyze the impact factors of the available peak regulation capacity and cost of CHP units, as well as verifying the effectiveness of the proposed dispatch method under the peak regulation compensation policy.
