Parallel operation of Multi-inverter can greatly improve the system's flexibility , power system's Capacity, redundancy and reliability, current through the power switch is divided, so the current stress for power switch can also be greatly reduced, the performance is improved with costs effective and power density. The conventional droop-control strategy which is adopted generally for parallel inverter regulates the phase and the amplitude of the output voltage according to output active power and reactive power,respectively.And active power and reactive power are related to both output amplitude and output phase for double closed-loop feedback voltage—source inverter.The control method of the droop control with virtual impedance is applied in this paper. The PQ droop control strategy for parallel single phase inverter is illustrated. PQ droop control scheme can effectively stabilize the droop control system to automatically exit, and also can achieve the expected load-sharing flow effect. Droop control without mutual connection, the inverter can be conveniently connected and removed. Finally, simulation results by obtained MATLAB / Simulink software is given to verify the effectiveness of theoretical analysis .
