摘　　要：随着新能源的发展,电力系统面临着间歇性电源占比持续扩大、调峰手段有限等诸多挑战,而电能存储技术是消纳规模化间歇性电源和促进智能电网建设的核心技术之一。在对储能技术研究现状和需求进行分析的基础上,提出了一种新的基于机械弹性的储能方法,论述了永磁电机式机械弹性储能机组和联动式储能箱的构成与工作原理,对其可行性与工程价值进行了初步分析,探讨了该储能方式需要解决的关键技术问题。Nowadays power systems are confronted with many challenges such as the continuous expansion of intermittent power sources and lack of means for peak regulation.Electric power energy storage is one of the core technologies for accommodating large-scale intermittent power and promoting smart grid construction.On the basis of a brief discussion on existing energy storage technologies and a description of the urgent needs of energy storage in power systems,a new way of energy storage based on mechanical elasticity is presented.The composition and operating principle of permanent magnet motor based mechanical elastic energy storage（MEES） unit and a linkage-type energy storage box are dealt with.Also,the engineering value and feasibility of the MEES unit is preliminarily analyzed.Finally,key technical issues for the MEES unit yet to be solved are explored to call academic and industry＇s attention.
