Integrated energy system optimization scheduling can improve energy efficiency and low carbon economy. This paper studies an electric-gas-heat integrated energy system, including the carbon capture system, energy coupling equipment, and renewable energy. An energy scheduling strategy based on deep reinforcement learning is proposed to minimize operation cost, carbon emission and enhance the power supply reliability. Firstly, the lowcarbon mathematical model of combined thermal and power unit, carbon capture system and power to gas unit (CCP) is established. Subsequently, we establish a low carbon multi-objective optimization model considering system operation cost, carbon emissions cost, integrated demand response, wind and photovoltaic curtailment, and load shedding costs. Furthermore, considering the intermittency of wind power generation and the flexibility of load demand, the low carbon economic dispatch problem is modeled as a Markov decision process. The twin delayed deep deterministic policy gradient (TD3) algorithm is used to solve the complex scheduling problem. The effectiveness of the proposed method is verified in the simulation case studies. Compared with TD3, SAC, A3C, DDPG and DQN algorithms, the operating cost is reduced by 8.6%, 4.3%, 6.1% and 8.0%.

“…Cui et al 26 proposed an environmental, economic dispatch model for the coordinated operation of the IES based on the ladder-type carbon trading mechanism and investigated the impact of the carbon trading price on IES operation. Ma et al 27 proposed a novel model and optimal dispatching mechanism for CHP and carbon capture systems based on the carbon trading mechanism, which successfully reduced carbon emissions and operating costs. These studies indicate that the carbon trading mechanism is widely used in the optimal operation of IES.…”
