摘要
针对中国北方集中供热下,热电联产机组的电热强耦合对风电消纳的不良影响,提出含电热泵和储热装置的热电联产调度模型。该模型通过电热泵的供热方式来解耦传统热电联产机组的热电关系,并利用储热装置来实现热负荷的实时转移增加供热系统的灵活性。为验证模型的有效性,本文提出一种基于SCA算法进行分解迭代的新求解方法,仿真结果表明含电热泵和储热装置的热电联调模型能够降低供能系统的运行成本,并有效缓解中国供热与风能利用的矛盾,提高风能利用率。
The regional integration of wind power could be restricted by a strong coupling of electric power generation dispatch and heat supply of combined heat-and-power(CHP)units.A cogeneration scheduling model containing electric the heating pump(EHP)and the thermal energy storage(TES)is proposed in view of the adverse effect caused by this coupling in winter.In the model,the electric heating pump is used to decouple the strong linkage of electric power and heat supplies.Meanwhile,the heat storage device is used to realize the real-time transfer of the heat loads and provides the necessary flexibility for the heating network.To verify the validity of the model,this paper proposes a new iterative method based on SCA decomposition algorithm.The simulation results show that the proposed model can decrease the operation cost and improve the utilization rate of wind energy.
