The ability of grid connected PV system to export power is dependent on the availability of the distribution or transmission network, when the grid get outage there is no exported power if there is sufficient solar radiation that due to the anti-islanding protection technic of the solar inverters. This work proposed to implement the PV system within micro-grid in order to improve its performance which is large effected by the heavily outages due to load separation policy that followed to reduce the demand during most year months in Karbala city which is taken as case study, MATLAB software is used to implement all required algorithms. The obtained results show that the proposed microgrid improved the performance of the PV system by keeping approximately same yield that obtained with normal grid and reducing the amount of imported energy from the grid as well the local generators of the selected microgrid by large amount which confirms the success of this system.
