Abstract: As to the drawbacks of traditional power system and the increasing demand for electricity, smart grid has been paid more attention and widely researched. And the base for realizing smart grid is to build advanced metering infrastructure based on smart meters(SM/AMI). In this paper, the structure and the role of SM/AMI in the power consumers and power grid corp are analyzed, and the influence of SM/AMI on the operation and management of distribution network and the electric power consumption behavior mode are demonstrated. In addition, the resource regulation strategy at power demand side based on SM/AMI is studied, the advanced application of SM/AMI is discussed, and the first Sino-Singapore eco-city smart grid integrated demonstration project of our country is introduced, which will have some reference value and guiding significance to the research of smart grid and smart distribution grid.
