【摘要】 随着新能源并网比例持续上升，电池储能系统（battery energy storage system,BESS）的发展备受关注。逐渐完善其激励政策和市场机制，提升其经济效益，对其未来发展具有重要意义。但目前BESS的不同物理特性、政策和市场机制、退役电池的处理方式等问题仍亟待深入研究。分析了BESS的研究现状，包括不同物理特性、参与电力系统价值评估现状。从国内外储能政策的提出、电力市场的运营、碳市场的交易等方面综述了国内外BESS需求及市场机制，并分析了梯次利用BESS的适用场景与经济效益。分析了目前BESS经济性研究方法和商业模式，提出了BESS参与电力系统存在的问题，并且提出改善建议。更多还原

【Abstract】 With the continuous increase of the proportion of renewable energy connected to the grid, the development of battery energy storage system(BESS) has attracted much attention. It is of great significance for the development of BESS in the future to gradually improve the methods of improving its economic benefits, incentive policies & market mechanisms,and battery hybrid utilization. However, the different physical characteristics, policies and market mechanisms of BESS, and the treatment methods of retired batteries are still to be solved.Therefore, this paper introduces the research status of BESS,including different physical characteristics, and economic evaluation. Secondly, worldwide BESS is summarized from the aspects of policy, power & market operation, carbon market transaction, etc. Thirdly, investigate the applicable scenarios and economic benefits of echelon utilization of BESS. In addition,the current BESS economic research methods and business models are reviewed. Finally, reveal the main problem of BESS participating in power system, and the suggestions of BESS in power system are put forward.更多还原
