Recently, advanced and intelligent power supply networks have been proposed under the concept of Smart Grid and smart meters have been implemented all over the world as the first step. While the first purpose of smart meter installation is improvement of metering business efficiency by automated and remote meter reading and tamper prevention by accurate and frequent meter readings, various new services...
For the realization of low carbonate energy supply, installation of renewable energy sources has been reinforced in Japan. In the effort, a major focus is on the photovoltaic system installation to low voltage consumers and thus it is expected that many photovoltaic systems will be connected to low voltage distribution systems. While photovoltaic system installations have various advantages, distribution...
The increase in energy consumption associated with ever-intensifying network traffic is becoming a major problem. A number of researchers have focused on technologies that dynamically adjust the processing performance and the link speed of routers according to the network traffic load in order to achieve energy-efficient networking. However, when such power-saving routers are present in an end-to-end...
