英文摘要：

The cyber physical system（CPS） is designed to realize the interoperability and deep integration of physical and cyber systems,so that it can obtain better operating effect and performance level beyond the traditional application system. The cyber physical system for power grid（Power CPS） is the development and application of CPS in the field of power grid. This paper analyzed the basic concepts and research status of CPS for power grid,and presented the research framework which is composed of four key techniques,including cyber and physical fusion modeling technique,Power CPS analysis method,grid control technique based on fusion model and formal verification based on fusion model. Moreover,the paper prospected the application of Power CPS in energy internet,active distribution network and traditional power grid.
