Fuzzy Type-II Controller based UPQC for Power Quality Enhancement in Grid Connected Micro Grid System

Micro grid is proposed in this paper to improve power quality in power distribution networks. The problem of power quality is addressed by (UPQC), cooperative control system for voltage harmonics,unbalances in micro grid(MG). Power control techniques employing one-stage converter for grid interaction MG system are presented in order to reduce many DC-AC-DC conversions in both AC,DC grids.The MG with suggested converter are used with variety of renewable energy sources, allowing for optimal power consumption in environ-mentally friendly settings with minimal losses, hence increasing system efficiency. The fuzzy type-II controller for frequency tracking,harmonic extraction in grid voltage,load currents is also proposed in this study. MATLAB/Simulink is used to verify this system, and the findings are adequate.
