| 摘要: |
| 在碳达峰、碳中和目标下，电力行业面临巨大的低碳转型压力。积极谋划煤电有序退出、在保证电网安全前提下加速清洁电源替代是实现双碳目标的必然选择。建立了煤电与清洁电源协同演进双层迭代优化模型。上层为电源投资决策模型，计及负荷和风光出力波动特性，以月为时间单位进行决策。下层是以运行经济性和满足调峰能力为目标的短期运行优化模型。进而，分析经济、技术、安全、环境因素对能源演进路径的影响，构建了对规划方案的综合评价指标体系，对能源演进路径薄弱环节进行辨识。最后，借助所提模型研究了某省级电力系统未来30年煤电与清洁电源协同演进路径，并对演进路径进行了综合评价，针对薄弱环节提出了相应的能源发展建议。 |

| Abstract: |
| With a goal of carbon peaking and carbon neutrality, the power industry is facing huge pressure of low carbon transformation. Actively planning is needed for the orderly withdrawal of coal power and accelerating the replacement of clean power sources while ensuring grid security. This paper establishes a two-layer iterative optimization model for the synergistic evolution of coal and clean power sources. The upper layer is a power source investment decision model that takes into account the fluctuating characteristics of load and wind-PV output, and makes decisions using the month as the time unit. The lower layer is a short-term operation optimization model that aims at operating economy and meeting peak regulation capacity. The impact of economic, technical, safety and environmental factors on the evolution path is analyzed, and a comprehensive evaluation index system is constructed to identify the weak links of the path. Finally, the proposed model is used to study the synergistic evolution path of coal power and clean power sources in a provincial power system over the next 30 years. A comprehensive evaluation of the evolution path is carried out, and targeted energy development suggestions are made for the weak links.
