Environmental concerns and low-carbon policies have intensified the carbon emission pressure for integrated energy systems (IES) to optimize their operation strategies. To address that, this paper establishes a bi-objective optimization model of integrated energy system operation with the consideration of total operation cost and carbon emission. A Nash-bargain-based approach is employed to determine a compromise solution between two objectives. Results indicate that the proposed approach can make a reasonable tradeoff between the operation cost and carbon emission.
