The detection and classification of power quality events that disturb the voltage and/or current waveforms in electrical distribution networks is very important to generate energy deliver this end-user equipment at an acceptable voltage. Various property extraction methods are used determine type disturbances signal. In study, seven distortions including sag, swell, harmonics, sag with swell fl...

This paper proposes a photovoltaic (PV) and battery interfaced series hybrid active power filter (SHAPF), which consists of series active power filter and an LC shunt passive filter. The main benefits of the proposed system provide the compensation against the voltage harmonics, current harmonics and voltage interruption for the whole day. A series active power filter (SAPF) demands a source of...

This paper presents a new algorithm for the determination of DC voltage source levels of asymmetric multilevel converters. This technique provides more flexibility to the designer and can generate a large number of levels (odd and even), with minimum number of single-phase full-bridge inverters. This point results in the reduction of switches number, losses, cost of the converter, installation ...

This article <span>addresses a variety of power quality concerns, including voltage sag and swell, surges, harmonics, so on, utilizing dynamic restorer (DVR). The proposed controller for DVR is proportional plus integral (PI) controller. Two methods are used tuning the parameters PI controller, trial error intelligent optimal method. utilized method particle swarm optimization (PSO) Resul...
