Abstract
To “bring carbon emissions to a peak by 2030 and to be carbon-neutral by 2060”, the role of renewable energy consumption and carbon emission trading are promoted. As an important energy consumer of regional energy system, it is necessary for integrated energy system to ensure the low-carbon economic operation of the system. Combined with the responsibility of renewable energy consumption, green certificate trading mechanism, carbon emission rights trading, and China Certified Emission Reduction (CCER), a regional integrated energy system operation optimization model was proposed. The model aims to minimize the total cost of the system, which included with electric bus, thermal bus, and cold bus. Setting different scenarios for the given example, the results show that the optimized model could effectively reduce the operating costs of the system. Moreover, the results also provide an effective reference for the system’s economic and low-carbon operation.

Summary
Under the recommendations for formulating China’s 14th five-year development plan and the long-range goals for 2035, China will pursue clean, low-carbon, safe, and efficient use of energy and accelerate the growth of new energy and green industries to promote greener economic and social development in all respects. An optimal scheduling model considering the uncertainty of wind power is proposed to minimize the cost and carbon emission and to maximize the energy utilization efficiency [8]. An operation optimization model of regional integrated energy system under the responsibility of renewable energy consumption is proposed to maximize the total revenue of the system, considering the green certificate transaction mechanism [9]. There are some studies on carbon emission constraints, a few studies take into account the impact of responsibility of renewable energy consumption, carbon emission trading, and CCER constraints on the optimal dispatching of regional-integrated energy system. Taking into account the impact of the responsibility of renewable energy consumption, green certificate trading, carbon emission trading, and CCER, an optimization operation model of a regional integrated energy system is proposed in this paper.
