Abstract

Considering that air source heat pumps have the advantages of fast heat supply response, high heat supply efficiency and environmental protection, air source heat pumps can quickly follow the change of wind power when wind power changes rapidly, and timely eliminate wind power. Air source heat pumps are considered in the day-ahead dispatch model of integrated electricity-heating system in this paper. The model regards generation cost for traditional units and combined heating power (CHP) units, operation cost for air source heat pumps and electric boilers and curtailment cost of wind power as its optimization target. The response speed of air source heat pumps and electric boilers are first considered in the constraint conditions. The wind power can be converted into heat energy by air source heat pumps so that improve the consumption of wind power when the wind curtailment is serious. The heat generated is used to provide system heat. The excess of heat can be stored in the thermal storage energy devices, which released to provide system heat at low troughs. Finally, the comparison between the examples shows that air source heat pumps not only can quickly respond to the change of wind power, but also have low operation cost and reduce system power generation cost .
