Recently, direct current (DC) micro grid proposed by some researchers in order to promote power quality and energy output. They conclude that whereas modern electrical loads and scattered energy resources are DC type inherently using DC micro grids  prevented from added translational  ac/dc or dc/ac. Thud,  others proposed Stability Analysis in HYBRID AC/DCMICROGRID to achieve higher energy output. A hybrid micro grid combined of two components: DC component and AC component. Scattered energy resources and   DC inherent loads connected to DC component and inherent AC resources and loads linked to AC component.  For power quality optimization, energy storage like batteries might connect to DC components at the other hand, system stability play significant role at  micro grids.in this article,  a hybrid micro grid composed of a wind turbine,  a photovoltaic unit (PV) and AC,DC loads simulated using MATLAB/SIMULINK. Considering solar and wind instability features, control plans designed for invertors so that preserve stability performance of hybrid micro grid connected to the web. Then, by error analysis in AC and DC sides,   error clearing critical time (CCT) obtained in both sides. Simulation results showed that error in AC side affects more on system stability.
