Design and application of smart power utilization system in pilot districts of Chongqing

This paper proposes an overall design for a smart power utilization system, and presents a realizable method based on practices in pilot districts in Chongqing. This design can effectively achieve data transmission and communication among many subsystems, while information management, monitoring, and controlling of smart power utilization districts in the subsystems are divided into different security zones. This system has two outstanding characteristics. One is that monitoring and accurate fault location for user's meters and power distribution equipment are realized through regional power distribution automation. The other is that electric vehicle charge pile management can make full use of peak and valley load shifting and realize efficient coordinate regulation by distribution load. This smart power utilization system has been successfully put into use in Jiaxinqinyuan and Fubaoquan districts in Chongqing.
