The thermal inertia of the district heating system (DHS), which are natural and great heat storages, have been considered in the combined heat and power (CHP) system operation to reduce wind curtailments. In this paper, according to the different thermal characteristics of public and residential buildings, a CHP system optimal operation model considering the thermal inertia of DHS and adopting a centralized control with flow varied by steps mode in DHS operation is proposed. Case study shows that the proposed model has much better performance in economic benefits and wind power integration.
