Voltage source converter based DSTATCOM has been accepted as the most preferred solution for reactive power management in distribution power networks which plays a vital role in improving power quality, correcting power factor and maintaining constant distribution voltages. However, the quality of DSTATCOM output voltage and current itself, such as injected harmonics and Total Harmonic Distortion...
To connect distributed generation units to a low-voltage four-wire distribution network, a suitable three-phase converter topology needs to be chosen. To improve the power quality in the grid, the distributed generation unit can be used as an active power filter (APF). When an active power filtering function is desired, the converter should have a neutral wire to allow neutral currents to flow. Therefore,...
This paper analyzes the effects of the decoupling of the cross-coupling terms when PI synchronous regulators are used in droop characteristic converter. The PI synchronous regulators are implemented for both voltage and current control. An analysis of the different working modes of the converter are presented. Three sub-modes for the island model, Conventional droop mode, power quality mode and Sync...
