    Integrated energy system (IES) plays a vital role in improving energy quality and efficiency of utilization, further improving environmental protection benefits and economic benefits, but its flexibility is greatly reduced by the coupling of internal unit output. Aiming at the problem, this paper studies the following work. First, the model of heat pump considering its operating characteristics to absorb electric energy and provide heat energy is established. Second, an optimal electricity-heat IES energy flow model considering the complementary relationship with heat pump is proposed, and the interior-point method is applied to solve this model. Third, a case study is carried out on the electricity-heat IES, and a comparative analysis on the running difference of district heating network between the energy flow and optimal energy flow is presented.
