This paper presents a novel planning model to determine the optimal sitting and sizing of the combined heat and power (CHP) unit in the integrated energy system (IES). Different from the traditional DG planning, the constraints of the power distribution system, heating system and gas distribution system are all considered. Therefore, the operating interaction between different energy systems can be taken into account. An integrated energy system consisting of a 14-bus electrical power system, a 31-node heating distribution system and a 12-node gas distribution system was used to demonstrate the effectiveness of the proposed optimization model. Simulation results showed that the optimal location and size of CHP can significantly improve the economy of the power system, and meet all the operating requirement of the electricity, heating and gas systems.
