The smart grid is transformation method for out-of-date electric allocation system, smart grid is a fresh solution of upcoming infrastructure. It is used to Shield, scrutinize and auto optimize the electric operations from very high voltage network to disseminated structure. The smart grid is a grouping of information and the communication knowledge, transmission and distribution system. The standing traditional grid wasfurther down pressure and challengedvaried issues. There are many modifications between smart and traditional grids such as two way operations instead of one way operations, computational intellect, self-monitoring abilities, cyber protected communication, safe, cost-effective environment. Number of various literatures discussed the positive topographiesof smart grid for power systems. In this paper deliberated about the evaluation about Grid Architecture typicalfinished the Function Layers mapped on Zones and domains.
