Background/Objectives: To simulate quadratic boost converter based AC micro grid system in open loop system; to simulate quadratic boost converter based AC micro grid system in closed-loop-system; to diminish THD of AC Micro-grid system using QBC; to enhance the-dynamic-response for AC Micro-grid system using QBC. Methods/Statistical analysis: Comparison of open loop, proportional integral & proportional resonant closed loop QBCIMGS(quadratic boost converter inverter micro grid system) is simulated using Mat lab SIMULINK. Findings: Comparison of open loop, proportional integral & proportional resonant closed loop QBCIMGS (quadratic boost converter inverter micro grid system) is simulated using Mat lab SIMULINK as it is done in terms of Settling time and steady state error. Both Settling time and steady state error is diminished using PR controller. Hence, PR controlled closed loop QBCIMGS is superior to PI controlled closed loop QBCIMGS. The benefits of-proposed-system are reduced harmonic-content and fast response. Improvements/Applications: By using PR controller, the settling time is reduced from 5.0 Sec to 3.6 Sec; the steady state error is reduced from 4.3 V to 3.3
