| 摘要: |
| 在“双碳”目标下，为提高风光能源利用效率、优化资源配置、促进综合能源系统降碳减排，提出了一种风光氢储综合能源系统低碳经济调度模型。首先，考虑氢能作为新型储能能源所具有的低碳特性和调度优势，引入两阶段运行的电转气(power-to-gas, P2G)技术模型，以氢能为连接纽带，实现了系统内电、热、气能之间的耦合传递。其次，引入碳捕集设备及阶梯式碳交易机制，以进一步降低系统的碳排放。然后，构建以购能成本、碳交易成本、运行成本和弃风弃光成本最小为目标的低碳经济调度模型，并运用CPLEX求解器进行求解。最后，通过对多个运行情景的优化结果对比分析，验证了模型在消纳风光出力、促进系统深度脱碳、推动多能源互补和增加系统经济效益方面的有效性。 |

| Abstract: |
| Given the goal of “dual-carbon”, to improve the utilization efficiency of wind and solar energy, optimize the allocation of resources and promote the carbon reduction of the integrated energy system (IES), a low-carbon economic scheduling model of a wind, solar, and hydrogen storage integrated energy system is proposed. First, considering the low-carbon characteristics and dispatching advantages of hydrogen energy as a new type of energy storage, a two-stage operation P2G model is introduced to realize the coupled transfer between electricity, heat and gas energy in the system with hydrogen energy as the connecting link. Secondly, carbon capture equipment and a stepped carbon trading mechanism are introduced to further reduce the carbon emission of the system. Then, a low-carbon economic dispatching objective is constructed to minimize the energy purchase, carbon trading, operational and wind and light abandonment costs, and the CPLEX solver is used to solve the problem. Finally, by comparing and analyzing the optimal results of several operating scenarios, the effectiveness of the model in absorbing wind and solar power output, promoting deep decarbonization of the system, promoting multi energy complementarity, and increasing system economic benefits are verified. |
