The resonance problems may arise among multi-connected LCL-filtered inverters and make the system instable. The recently proposed GSPWM can reduce the filter order without reducing other performance in large-scale application, which has potential to avoid the resonance. But GSPWM will introduce specific phase delay to PWM sequences and it may influence the response character in different grid conditions...
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...
Traditionally, the parallel-connected multileg inverter could assume the interleaved pulse width modulation (PWM) to attenuate the high-frequency harmonics by using a single controller to generate the corresponding interleaved switching sequences. However, the interleaved PWM cannot be employed in multiple distributed independent inverters installed at different locations with their own controllers...
The distributed inverters are generally integrated into power grid without switching sequence coordinated control capability since they are equipped with their own micro controllers to command the output quantities. The switching ripples of all distributed inverters will then be randomly accumulated at the point of common coupling. The recently proposed global synchronous pulsewidth modulation (GSPWM)...
