An improved control scheme based in droop characteristic control for microgrid converters

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 mode are analyzed. One mode for grid connected mode, Grid supporting mode is analyzed.
