| Popis: | In this study, a cascaded single-phase converter topology is proposed for single-phase microgrid integrated into high-voltage power distribution systems. In this system, the lower single-phase converter works in voltage controlled mode to reduce the harmonic distortions of supply voltage to local critical load. At the same time, the upper single-phase converter is placed in between the main grid and the output of the lower single-phase converter. Alternatively, the upper power cell works in current controlled mode to block the harmonic current pollutions from the local non-linear load. Through collaborative control of the cascaded upper and lower converter, the proposed system can provide active harmonic filtering to both single-phase supply voltage and single-phase grid current, but without any harmonic extractions in the entire process. |
