Abstract: Grid tied inverters are used to feed power produced by the renewable energy sources to the local power grid. India has a total grid interactive renewable power plant capacity of 84.39 GW, consisting of solar 31.10 GW, wind 36.93 GW, small hydro 4.61 GW and bio-power 9.94 GW. Solar and wind energy sources are most abundantly available in India and has various advantages over other energy sources but combining these two intermittent sources for the purpose of exporting the generated power through grid tied inverter has many challenging issues. In this paper, various literatures, standards and patents are reviewed to understand the function of grid tied inverters, power quality, islanding detection, overvoltage protection and safety issues. This review can help the readers in understanding the basics of the grid tied inverters and also provide information on selecting the suitable inverters for renewable energy applications.

Keywords: grid tied inverters; controllers; renewable energy; solar; wind; standards; patents; power quality.
