Abstract: Wind power integration may be restricted due to the asynchrony of electricity and heat loads and the strong coupling between the power generation and heat production of combined heat and power (CHP) units. The price-based integrated demand response (PBIDR) can adjust electricity and heat loads to accommodate wind power. But, it is tricky to formulate appropriate electricity and heat prices to make the system having enough flexibility and achieves the best economic benefits. This paper proposes a robust dispatch model for integrated electricity and heat networks (IEHNs) based on PBIDR. The linear model of the district heating network (DHN) is first derived based on the equivalent infinitesimal replacement theorem and the assumption that the supply temperatures at load nodes are approximately equal. Then, a computationally tractable PBIDR model is formulated in terms of the theory of price elasticity of demand and the concept of thermal sensation vote (TSV). Finally, the dispatch model is constructed as a two-stage robust optimization problem to hedge the uncertainty of the wind power output, the ambient temperature, and the PBIDR. The effectiveness of the proposed model is verified by two different scale test systems.
