The design and implementation of a smart tap for policy-based power management

To cope with the recent increase of energy consumption in homes and to achieve efficient usage of the distributed power generation, there has arisen a novel concept of i-Energy home energy management. Toward realizing it, the authors have designed and implemented a smart tap, an intelligent power strip with communication, power sensing and control functions. The power management done by the smart tap is policy-based so that users can set versatile policies depending on their preferences. As an application of the policy-based power management, the authors have implemented a software-based breaker function on the smart tap.

Smart Outlet Network for Energy-Aware Services Utilizing Various Sensor Information

This paper describes the construction of a smart outlet network as a system for automated energy-aware services utilizing various sensor information. With high-granularity sensing of power consumption of each electrical appliance in home, and with environmental (humidity, temperature, light) sensors and a motion sensor installed on the smart outlets, the appliances are under policy-based automatic control. The authors have deployed the system in real-life environments, and have implemented the following functions and power management policies, 1) visualization of power consumption data of appliances for enhancing energy-awareness, 2) policy-based power control utilizing various sensor information collected at the smart outlets, 3) automatic coordination of multiple or different appliances in both centralized and distributed manners.
