Abstract: Microgrids (MGs) and Distributed Generation are becoming an important role because of their peculiar characteristics. MGs are composed of small power sources which can be renewable, placed near customer sites. Moreover, they have the inherent property of islanding. The attention focuses on the control technique of the converters during grid connected and islanding operation of the MGs. The converters can be represented as an ideal converter with its specified parameters and proper control techniques. Some of the power converters like voltage source converters or current source converters are analysed based on the grid requirement in the system. Similarly some of the control loops like voltage control, current control or power control can be analysed based on the performance of the grid connection. Based on these conditions we may have the attention towards the phase transformations for the control strategies. All the control operations with their performances can be simulated using MATLAB/SIMULINK.
