| 对源侧进行低碳化改造、荷侧辅以综合需求响应策略有利于“双碳”目标的实现。为此，提出一种多时间尺度下计及综合需求响应和碳捕集-电转气联合运行的综合能源系统低碳优化调度策略。源侧在碳捕集电厂中引入储液罐，形成碳捕集电厂的综合灵活运行方式，并构建计及碳捕集电厂和电转气设备的新型联合运行模型；在荷侧分析需求侧资源在不同时间尺度下的响应特性，建立不同时间尺度下的价格型、激励型需求响应模型，通过源荷协调配合提升系统的低碳性能；提出源荷互补的综合能源系统多时间尺度低碳调度策略，构建含综合需求响应的日前-日内-实时调度模型。算例结果表明，所提模型能够充分利用源荷资源参与调节，实现系统低碳、经济、稳定运行。 |

| Abstract: |
| Low carbonization transformation on the source side assisted by comprehensive demand response strategy on the load side is beneficial for achieving the “dual carbon” goal. Therefore, a low-carbon optimal scheduling strategy of integrated energy system considering integrated demand response and joint operation of carbon capture and power-to-gas under multiple time scales is proposed. The liquid storage tank is introduced into the carbon capture power plant on the source side, forming a comprehensive and flexible operation mode of the carbon capture power plant. And a new joint operation model of the carbon capture power plant and the power-to-gas equipment is constructed. The response characteristics of demand side resources under different time scales on the load side are analyzed, and the price-based and incentive-based demand response models under different time scales are established, and the low-carbon performance of system is improved through source load coordination. Finally, a multi-time scale low-carbon scheduling strategy of integrated energy system with complementary sources and loads is proposed, and a day-ahead, intra-day and real-time scheduling model with integrated demand response is constructed. The case study results show that the proposed model can make full use of the source and load resources to participate in regulation and achieve low-carbon, economic and stable operation of the system. |
