This paper reviews the importance of a flexible ac distribution system device for microgrid applications. The device aims to improve the power quality and reliability of the overall power distribution system that the microgrid is connected to. Extended Kalman filters are also studied for frequency tracking and to extract the harmonic spectra of the grid voltage and the load currents in the microgrid. Also this paper high lights on DG grouping in order to harmonize the investment of assets, the quality of power supply and the cooperation with the existing power grid.
