摘要：The distributed inverters are integrated into grid without coordinated PWM and the switching ripples of inverters are randomly accumulated at point of common coupling (PCC). Global synchronous pulse width modulation (GSPWM) can attenuate the accumulated switching ripples. This paper proposes time compensation method which compensates the time delay of synchronization signals for inverters in distance. Then, this paper proposes distributed calculation method for optimal phase shift and synchronization frequency in large-scale application. This new method is much faster than before. Finally, Matlab simulations and experimental results are presents to verify the performance of proposed methods.
