【摘要】 认为随着科技进步和社会需求的推动,电网正从传统的输、变、配电加速向以满足社会资源优化配置为主要功能的能量承载、能源博弈的平台演化。通过能量存储、不同形式能量转换及其相互替代技术的应用,电网将充分发挥能量载体、传输功能,实现能量流、信息流和业务流的融合。依据电网建设重点和技术应用特征,文中将其划分为坚强互联、开放互动、柔性可控3个阶段形态。欧美国家倡导的智能电网和中国国家电网公司提出的加快建设坚强智能电网均为这一过程的体现,反映了不同国情中电网建设不同阶段的客观需求。未来电网长远形态难以准确预见,但其网络、能量载体等属性将随着技术和时代进步不断被发掘、拓展,必将在未来社会生产、生活中发挥更大作用。更多还原

【Abstract】 This paper is concluded that,with the breakthrough and wide implementation of energy storage,different form energy converting and mutually alternative technologies,the power grid will more serve as a game platform for different energy resources than a traditional power transmission,transformation,and distribution grid.According to the main functions and key technologies,the evolution procedure is divided as three stages:strong inter-connective,open and interactive,flexible and controllable.As the production of this procedure,the smart grids initiated in China,America and Europe are analyzed.It is hard to foresee the long term form of future grid,but its characteristics such as interconnected grid,energy carrier will be further exploited fully.更多还原
