This chapter presents the design and implementation of the intelligent power management system, which consists of three part: the intelligent Electronic Power Meter (iEPM), the intelligent Electronic Management Concentrator (iEMC), and the intelligent Centralized Database Server (iCDS). The iEPM will be installed in every home of building; because it is based on the technology of impendence identification, iEPM can automatically distinguish which electronic appliance is connected in home. The iEPM is a high precision electronic power meter, so it can replace Electricity Meter currently and require no extra indoor wires. A certain amount of iEPM can be added to a group controlled by an iEMC which adopts the technology of WiFi-based WSN so that it can exchange the message with iCDS. The iCDS solves the key problem of system extension by using the multi-layered architecture; it can automatically send data to the iEPM or update the program of the iEPM. The intelligent power management system can make people use power with safety and efficiency. Using this system, the users or managers of the building can decide which electronic appliance can be used in which time up to their requirement. The system has been widely used in many universities of Tianjin in China, such as Tianjin Normal University, Tianjin Business University, Tianjin Medical University, and so on.
