N2 - In this paper, an iteration method was proposed for calculating the optimal energy flow in a combined heating and electricity system. A basic model of the combined heating and electricity network which consists of electrical distribution network, heating network and combined heating and power units (CHP) was presented firstly. The nonlinear and nonconvex constraints of heating network make the optimal energy flow hard to solve, thus a piecewise linear approximation method is applied to simplify the model, and then, an iteration method based on the mixed integer linear programming was proposed. By considering the temperature difference in heating network energy flow calculation, the proposed iteration method make the results more accurate. Finally, a case study conducted on a 66 bus combined heating and electricity system to demonstrate the effectiveness and superiority of the proposed method.
