| 摘要: |
| 加快风电等新能源快速发展是实现“双碳”战略的关键路径。但随着“十四五”末期风电退役潮的到来，我国将面临大规模风电退役和再建的问题，这将严重威胁电力系统的供电充裕性与灵活性。在此背景下，煤电仍是电力保供和灵活调节的重要基石，因此需要统筹协同发展风电与煤电。为此，提出了一种考虑风电退役再建和煤电灵活性改造的低碳电力系统多阶段协同规划方法。首先，建立了考虑系统供电充裕性的风电直接退役和延寿改造有序退役模型，并提出“以大代小-等容改造和扩容改造”的风电场多路径原址再建方案。在此基础上，考虑煤电灵活性改造对新能源消纳的影响，构建了内嵌系统运行模拟的风电和煤电改造协同规划模型。最后，以改进IEEE39节点系统为例进行算例分析，结果表明所提方法可以给出保障系统供电充裕性的风电退役和再建方案，且通过煤电灵活性改造能有效满足风电场扩容后的灵活性需求。 |

| Abstract: |
| Accelerating the rapid development of new energy sources such as wind power is a key path to achieve the “dual carbon” goals. However, with the approaching wave of wind power decommissioning near the end of the 14th Five-Year Plan, China will face the challenges of large-scale wind power decommissioning and reconstruction, which will seriously threaten the power system’s supply adequacy and flexibility. In this context, coal power remains an important cornerstone for power supply security and flexible regulation, necessitating coordinated development of wind power and coal power. To this end, a multi-stage coordinated planning method for low-carbon power systems considering wind power decommissioning and reconstruction and coal power flexibility upgrades is proposed. First, a model for direct decommissioning of wind power and orderly decommissioning of life extension retrofit considering system supply adequacy is established. A multi-path in-situ reconstruction scheme of wind farm is then proposed, featuring "large replacing small” and “capacity-equivalent retrofit expansion upgrades”. On this basis, considering the impact of coal power flexibility upgrades on new energy consumption, a coordinated planning model of wind power and coal power upgrades is constructed. Finally, a case study using the improved IEEE 39-bus system shows that the proposed method can provide wind power decommissioning and reconstruction schemes to ensure system supply adequacy. In addition, coal power flexibility upgrades can effectively meet the flexibility demands following wind farm expansions. |
