热电联产型共享储能的技经分析与市场机制研究

Technology and Economic Analysis and Market Mechanism Research of Cogeneration Shared Energy Storage

  • 摘要: 以可再生能源和储能为主体的新型能源系统建设已成为能源转型的发展趋势。针对当前电化学储能面临技术经济性差以及供用能在品质上存在不匹配的问题,基于能量梯级综合利用的理念和共享经济的模式,提出热电联产型共享储能系统的技术与业态,探讨该类储能的基本运行原理、技术经济特性和商业模式。以高温固体蓄热、余热锅炉与汽轮机组成的典型热电联产型共享储能系统的案例分析表明,以固体蓄热为储能设备的热电联产型共享储能系统,在现有市场环境下实现系统经济性最优的容量配置和运行调度时,系统内部收益率达到10.6%、投资回收期为8.2 a。同时,研究并揭示了容量租赁比例、辅助服务价格、供热以及储能单位投资对共享储能电站技术经济性能的影响规律。最后,从技术及市场层面对热电联产型共享储能系统存在的等效储能容量、多重收益模式等关键问题进行了讨论。

     

    Abstract: The construction of a new energy system dominated by renewable energy and energy storage has become the development trend of energy transformation. Aiming at the problems of the poor economy of electrochemical energy storage technology and the mismatch between supply and demand of energy quality, based on the concept of energy cascade utilization and the business model of the sharing economy,this paper explores the new technologies and new business forms of shared energy storage stations for cogeneration and discusses the basic operation principles, technical and economic characteristics and business models of this energy storage mode. The case analysis of a typical cogeneration shared energy storage power station consisting of high-temperature solid heat storage, waste heat boiler, and steam turbine shows that under the current market environment, the internal rate of return is 10.6% and the payback period is 8.2 years when the solid heat storage as energy storage equipment is optimized for economic optimization. Meanwhile, the study reveals the influence rules of capacity leasing ratio, ancillary service price, heating, and energy storage unit investment on the technical and economic performance of the shared energy storage station. Finally, key issues such as equivalent energy storage capacity and multiple income models of cogeneration shared energy storage stations are discussed from technical and market perspectives.
