This paper is mainly focused on the implementation of fuzzy logic based UPFC controller in the isolated wind-diesel-micro hydro system for management of reactive power and enhancement of voltage stability. For better analysis a linearised small signal transfer function system is considered for different load inputs. The fuzzy based UPFC controller has been tunned to improve the reactive power of the off grid system. Simulation in MATLAB environment has been carried out and the effectiveness of fuzzy tuned controller is established..
