Japanese Trend of Advanced Smart Grid Technology for Harmonization of Renewable Energy Resources and Power Systems

Abstract

In tandem with the penetration of Renewable Energy Sources (RES) such as photovoltaic and wind power generation to reduce CO₂ emissions and conserve energy, development of advanced smart grid technologies is needed to secure a stable power supply of grid with RES by controlling power quality (voltage and frequency) within each secure range. This paper describes Japanese trend of the advanced smart grid technologies to harmonize RES and conventional bulk power system. Furthermore, several ongoing field tests to try to realize Japanese version of smart grid are briefly introduced.
