Functions and operational experiences of real scale smart grid experimental system

Abstract

This paper introduces a real scale smart grid experimental system installed at Fukushima National College of Technology, Japan. The system is composed by real scale micro grid with a solar power generating system, wind power generators and a gas-engine co-generation system, etc. In the system, such important loads as lighting of main building are supplied through uninterruptible power supply system (UPS) and some other loads are connected to the system directly. The system also has experimental connector panel to which any kind of load and smart meters can be connected. So as to develop new functions of smart grids, a real time simulator is also installed.
