| 摘要: |
| 针对电转气(P2G)、碳捕集系统在运行时间上存在的不同步问题，将储液罐作为CO2 “缓冲站”连接碳捕集电厂(CCPP)与P2G，构建考虑综合灵活运行方式的CCPP与P2G联合运行的综合能源系统(IES)低碳经济调度模型。通过研究储液罐的“能量时移”特性，分析包含储液罐的P2G-CCPP新型联合运行模式对于促进风电消纳、降低碳排放的积极影响，基于此建立考虑CCPP综合灵活运行方式以IES总运行成本最小为目标的低碳经济调度模型，在CPLEX中以改进的IEEE 39节点电力网络模型和7节点天然气网络模型为例进行仿真验证，结果证明所提运行方式对于实现IES低碳经济调度有重要的借鉴作用。 |

| Abstract: |
| Aiming at the asynchronous problem about the running time of power-to-gas(P2G) and carbon capture system, the liquid storage tank is taken as the CO2 “buffer station” connecting carbon capture power plant(CCPP) and P2G, and the low-carbon economic dispatching model of integrated energy system(IES) is constructed, which considers the comprehensive and flexible operation mode of CCPP with the joint operation of P2G. By studying the “energy time-shift” characteristics of the liquid storage tank, the positive impacts of the novel P2G-CCPP joint operation mode including the liquid storage tank on promoting wind power consumption and reducing carbon emission are analyzed. On this basis, the low-carbon economic dispatching model taking the minimum total operation cost as the objective is built, which considers the comprehensive and flexible operation mode of CCPP. The improved IEEE 39-bus power network model and 7-node natural gas network model are taken as examples to carry on simulation and verification in CPLEX, and the results verify that the proposed operation mode can provide an important reference for achieving low-carbon economic dispatching of IES. |
