چکیده مقاله:

The distributed generations which have not connected to main grid, so there are controlling issues, in the Islanding Microgrid. Such as voltage, frequency and current control .Therefore, designing and selection of a robust controller against disturbances and load changes are very importance. In this paper, we have used hysteresis controller to control voltage in IMG and used an adaptive control system and sliding mode control to regulate current and load sharing between DGs inverter. The under studying system have three DGs which is connected to each in parallel. One of DGs is selected as a voltage controller unit and are 2 other units are in the current controlling state .This controller resulted stability increase and robusted control system against load changes. In this study has been evaluated the performance load characteristics such as symmetrical ohmic, unsymmetrical ohmic, inductive ohmic and non-linear ohmic has been studied for IMG in MATLAB/Simulink software
