中文摘要:可再生能源发电的消纳是能源利用低碳转型的关键问题，储能是平抑可再生能源发电波动的重要手段。在此背景下，针对含先进绝热压缩空气储能（advanced adiabatic compressed air energy storage，AA-CAES）和风电的电力系统，提出风电消纳的低碳调度方法，并建立能-碳追踪模型追溯负荷侧电能与碳的具体来源。首先，建立了电能-碳流追踪模型，其次，建立了AA-CAES电站运行模型和风电出力模型。之后，以常规机组运行成本、碳排放成本之和最小为优化目标，构建了含AA-CAES与风电的电力系统协同低碳调度模型。最后，以改进的IEEE 30节点系统为例，对AA-CAES/风电协同调度进行了计算与能碳溯源分析。结果表明，AA-CAES电站在电力系统中发挥了重要作用。在低负荷时段，AA-CAES电站主要处于压缩充电状态，储存电能；在高负荷时段，尤其是在风力发电出力不足时，AA-CAES电站通过膨胀放电来提供电能，有效平抑了风电的波动性。并通过能碳溯源分析，清晰地划分出AA-CAES/风电协同作用区域，显示出系统在不同负荷水平下的灵活响应能力。

Abstract:The accommodation and consumption of renewable energy generation is a key issue in the low-carbon transition of energy utilization， while energy storage is a crucial means to mitigate the fluctuations in renewable energy generation. Against this backdrop， a low-carbon dispatching method for wind power consumption is proposed for power systems containing advanced adiabatic compressed air energy storage （AA-CAES） and wind power， and an energy-carbon tracking model is established to trace the specific sources of electricity and carbon on the demand side. First， the power flow-carbon tracking model is introduced. Second， operational models for AA-CAES power plants and wind power generation are developed. Third， the low-carbon scheduling model for the wind power generation coordinated with AA-CAES is formulated. Subsequently， with the objective of minimizing the sum of conventional unit operation costs and carbon emission costs， a collaborative low-carbon dispatching model for power systems containing AA-CAES and wind power is constructed. Finally， taking the improved IEEE 30-bus system as an example， calculations and energy-carbon traceability analysis are conducted for the coordinated dispatch of AA-CAES and wind power.The results demonstrate that the AA-CAES plays a significant role in the power system. During periods of low load， the AA-CAES primarily operates in a compression charging state to store electrical energy. In contrast， during high load periods， particularly when wind power generation is insufficient， the AA-CAES provides electricity through expansion discharge， effectively mitigating the variability of wind power. Furthermore， through an energy-carbon traceability analysis， the synergistic effect areas of AA-CAES/wind power are clearly delineated， demonstrating the system’s flexible response capabilities under different load levels.
