We have to design a system model in MATLAB 2015A software. In this analysis micro-grid 33 bus system data Power generation source are used PV these are provide constant DC outcome then these outcome improving to dc level, used dc to dc convertor. DC/DC convertor output to connect three phase invertor system. In this invertor gate pulse control using FACT- VSC device with fuzzy logic, VSC provide fixed pulse with constant duty cycle. Our proposed system optimization of 33 bus system data power loss, faulty bus and DG placement in term of stability index.
