摘　　要：信息系统作为当前社会经济数字化转型的基础设施,其对物质世界的细粒度管控是以能耗为代价的。随着数字化转型发展的加速,信息系统的可持续性和供电系统效率已经面临巨大压力。该文从自然界"物质–信息–能量"的基础三元关系出发,初步探讨信息系统的可持续性、信息能量的基本互换关系、计算功耗构成及软件功耗模型,进而提出和论述信息系统是一种"数字电网"和信息负荷调度能力是一种"新型发电能力"的观点,通过广域信息负荷与电力负荷联合调度达到信息系统的可持续发展和大电网安全稳定运行,为未来高弹性电力系统的建设提供了一种新的思路。Information system is the cornerstone of the digital transformation of social management and economic development,which is building up on energy consumption.With the fast-paced social-economic transformation,the sustainability of information system has been more and more crucial.In this article,based on the fundamental relations among"Mass-Information-Energy",we have discussed the status quo of energy consumption of information system,the intrinsic relation between information and energy,the fundamentals of information system energy consumption.Then,we have proposed a new point of stand:ICT(information and communication technology)system should be regarded as a new kind of"digital power grid"and the ability of computing load scheduling is a new kind of"power generation".This new perspective will enable us to fulfill the sustainability of information system and the stability of traditional power grid,providing design insight to how to build the future high resilient power grid.
