Abstract

Current problems related to the power grid in Japan include the large-scale introduction of natural energy resources and summertime peak power cutting and shifting. Data centers face similar problems with concern for instability in the power supply system caused by sharp changes in load such as server power consumption and diversification in server power consumption patterns. As a solution to such problems, we have investigated a method for switching power flow by power semiconductors via economical 920 MHz band wireless communication to control the rise and fall in power in real time has been studied. We have fabricated a mini-model and used it to test the basic operating sequence. We report basic guidelines for using this system to improve the real-time performance of an economical wireless communication system and a source routing technique for improving reliability.
