In this paper a technical review of parallel operation of power electronics inverters for load sharing conditions in distributed generation (DG) network is presented. Emphasis is given to parallel operation of Active Power Filters (APFs) as they are widely used to mitigate load current...

Harmonics estimation methods are analyzed in presence of different power quality problems, namely voltage sags, voltage unbalance, voltage distortion and variations of power supply frequency. The harmonics detection algorithms are based on the instantaneous reactive power (IRP) theory, the...

Parallel to growing grid-integrated applications, the power converters have been an important research field for the power conversion and power quality. The converters can be used in different power levels ranging from large adjustable speed drives to low power household applications and office...
