In this paper, an optimizing operation model of integrated energy system (IES) based on distribution network and natural gas network is proposed. While meeting the safety operation constraints of these two networks, the cost of energy for the integrated energy system is minimized at the same time. The proposed model is a comprehensive non-convex problem which is difficult to solve. In order to solve this problem, the incremental piecewise linearization as well as second order cone relaxation (SOCR) is applied to convert the original model into a convex problem. Therefore, the operational scheme of the integrated energy system can be obtained through solving the prosed model. Finally, the effectiveness of the prosed model was verified by simulation on an integrated energy system consisting of the 20-node natural gas network and IEEE 14 node system.
