Abstract

Combined heating and power integrated energy system (CHP-IES) enables efficient coordination and dispatch of multiple energy sources, enhancing renewable energy utilization and overall efficiency, thus serving as a key technical approach to support the low-carbon transition under the dual carbon goals. First, the paper develops a detailed model of key components in the system, including gas turbines, gas-fired boilers, electrical energy storage, and thermal energy storage, thereby capturing the multi-energy flow coupling relationships within CHP-IES. Second, a pricing mechanism based on the Stackelberg game is established, in which the distributed energy resource (DER) operator acts as the leader and the users serve as followers. The CHP-IES dynamically determines electricity and heat prices based on market signals, while users adjust their flexible electricity and heat loads in response to price signals. Finally, the proposed method is validated through a case study.
