In this paper, the authors discuss a power allocation management system to maximize user's Quality-of-Life, keeping total power consumption within a limited amount of available power, which is implemented utilizing smart outlets, a controller and a power allocation algorithm. We can treat power allocation for energy-saving and reducing peak load as the knapsack problem, regarding that an appliance...
This paper describes the implementation and evaluation of a system for allocating power efficiently to appliances utilizing an algorithm for the knapsack problem. The algorithm is implemented on a smart outlet, which is able to measure power consumption of connected appliances and control appliances based on various policies. Keeping total power consumption of appliances under a threshold with maximizing...
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...
In this paper, the design and implementation of a policy-based power router with power sensors is described. The power router has two inputs and two outputs, and has capability of circuit-switching between sources and appliances depending on various switching policies for efficient allocation of energy. As an example of a policy-based automatic power allocation, the authors have implemented a prototype...
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...
