| 随着高比例新能源并网与电力市场化改革的深入,传统发电机组固定成本回收和系统容量充裕性成为关键问题。在此背景下,提出了适应电源结构深度转型的分阶段容量充裕性保障机制,涵盖试点期固定容量补偿、过渡期分类竞价补偿机制与成熟期统一容量市场3个演进阶段。首先,开发了基于跨市场预期收益设计固定容量核算方法,保障初期基础灵活性电源的固定成本回收;其次,针对异质资源调节特性构建分类竞价补偿模型,引导各类灵活性资源独立竞价;最后,设计统一容量市场集中出清机制以统筹长期容量投资决策。算例结果表明:所提出的分阶段容量充裕性保障机制能够保障发电企业有效收回固定成本,引导新型储能等灵活性资源的合理投资,进而保障系统长效容量充裕度与灵活调节能力。 |

| With the integration of high shares of renewable energy into power systems and the deepening of market-oriented electricity reform, fixed cost recovery for conventional generating units and system capacity adequacy have become critical issues. Given this background, a staged capacity adequacy assurance mechanism adapted to the deep transition of the power supply structure is proposed, covering three evolutionary stages: fixed capacity compensation in the pilot stage, category-specific auction-based capacity compensation in the transition stage, and a unified capacity market in the mature stage. First, a fixed capacity accounting method based on expected cross-market revenues is developed to support fixed cost recovery for essential flexible generation resources in the initial stage. Then, a category-specific auction-based capacity compensation model is established according to the regulation characteristics of heterogeneous resources, guiding different types of flexible resources to bid independently. Finally, a centralized clearing mechanism for the unified capacity market is designed to coordinate long-term capacity investment decisions. It is demonstrated through case studies that the proposed staged mechanism supports effective fixed cost recovery for gen-eration companies, guides rational investment in flexible resources such as new-type energy storage, and ensures long-term system capacity adequacy and flexible regulation capability. |
