Abstract: This paper is representation a unified controller stratagem intended for DG during equally grid tied and island modes. The current references generation part module is analyzed a unified controller stratagem in both modes. The proposed controller strategies compose of a novel, voltage loop with an inner inductor, current loop within the synchronous reference frames. The module elements preserve analyze through two aspects. Primary, through introducing P compensator with Q-axis furthermore PI compensator with D-axis correspondingly, an internal inductor current loop controller is activating in the grid tied mode and preserve be mechanically inactivated upon occurrences of island. Thus, for the detection of uncertain islanding or two different controllers modes there is no want for two switches and change from the grid tied mode toward the island mode, the load voltage worth is able to enhance. The module next part is to nearby the load current, feed forward in direction of compact with the problem caused through the non-linear local load, in these, not only the waveform of the grid current inside grid tied is enhanced, but also the worth of the loaded voltage inside the island mode is enhanced. In conclusion the effectiveness of the propose controller stratagem and fuzzy control are validated through the simulation results.
