摘要:

目前,储能需求的研究多集中于特定应用场景中电化学电池等持续放电时间较短的储能装置的配置,缺乏对系统整体性储能需求规划的方法及经济性影响的研究。针对短时和长期2种不同类型储能的特点,建立了以系统综合成本最低为优化目标的量化分析模型和方法,从总量、结构和成本3个维度量化分析系统级储能需求,将储能规划嵌入电源规划的混合整数优化问题中统一求解。以欧洲、全球和中国为算例,分析支撑能源清洁转型电力系统所需的储能种类、储能装机容量和可接受的储能成本。结果表明,仅依靠以锂离子电池为代表的短时储能无法满足未来高比例可再生能源场景的全部系统要求,长期储能将在2035年后的深度清洁转型中逐步发挥重要作用。

Abstract:

At present, the research on energy storage demand mostly focuses on the configuration of energy storage devices, such as electrochemical cells with short discharging time in specific application scenarios, and there is a lack of research on the planning method of system-level energy storage demand and the impact on the overall cost. Aiming at the characteristics of two different types of short-time and long-time energy storage, a quantitative analysis model and a method with the optimization goal of the lowest system comprehensive cost are established. The system-level energy storage demand considering three key factors, namely, the capacity, the structure, and the cost is quantitatively analyzed. The energy storage planning is solved jointly with the power supply planning problem through the mixed integer optimization. Taking Europe, the world and China as examples, the energy storage type, installed capacity and acceptable cost of energy storage to support the clean energy transition of power system are analyzed. The results show that the short-time energy storage which is only represented by the lithium battery cannot meet all the system requirements of the scenarios with high proportion of renewable energy in the future, and the long-time energy storage will gradually play a significant role in the deep clean transition after 2035.
