Optimal Dispatch of Combined Heat and Power System with Distributed Heat Pumps Chen Cheng, Ye Zhihao, Xia Yihui, Yu Yanjuan



Utilizing heat pumps (HPs) is recognized as a promising approach to promote the flexibility of the combined heat and power (CHP) units for better wind power integration in the combined heat and power system (CHPS). This paper investigates the coordinated operation of the CHP units with the HPs which are distributed at heat exchange stations (HES). We propose the method for controlling the on-off status and running power of the HPs considering the thermal inertia of the district heating system (DHS). Finally, the optimal dispatch model of the CHPS is established. The effectiveness of the distributed HPs on reducing wind power curtailment is verified with numerical studies.
