The Microgrid Systems: An Overview in Turkey and The World

Abstract

Necessity and important of electric energy has been on increase because of development in technology and economy. When compared with renewable energy sources, electric energy obtained from fossil fuels has the biggest share. But demand to renewable energy sources has been increased instead of fossil fuels due to carbon dioxide emissions, risk of being used up over and above high energy cost. Distributed energy sources (wind energy, solar energy, fuel cell, etc.) can be installed to close areas to consumers. So distributed energy sources with microgrid design can be used as cost effective, reliable and efficient. Microgrids are small scale energy network that can provide uninterrupted energy with high power quality to different types small load community and can meet technological preferences of consumers so power quality demand. Microgrid systems in interconnected to distribution grid or islanded mode; obtain coordinated operation of energy sources (micro turbines, fuel cells, photovoltaic, etc), storage devices (flywheels, energy capacitors and batteries) and loads. In this study, potential of microgrid system in Turkey and world, technological development at microgrid systems and usage state of these technologies in Turkey and world were evaluated. It was exhibited that attaching importance to microgrid systems provides increment in usage of renewable energy.
