TL;DR: The feasibility of using a simple power factor-frequency inverse droop control for series-connected islanding microconverters and the accuracy of power sharing is not affected by the variations of microgrid feeder parameters or the disturbance of the point of common coupling (PCC) nonlinear loads.

TL;DR: In this paper, a new simultaneous supply voltage and grid current harmonic compensation strategy is proposed using coordinated control of two shunt interfacing converters, where the first converter is responsible for local load supply voltage harmonic suppression and the second converter is used to mitigate the harmonic current produced by the interaction between the first interfacing converter and the local nonlinear load.

TL;DR: A modified double-loop voltage controller is developed to enhance the power sharing control of islanding microgrid, without the involvement of conventional droop control concept, and a proper power sharing and nearly zero PCC voltage control error can be achieved.

TL;DR: A modified weighted average current controller is developed based on a reduced-order virtual filter plant to realize a fast line current response, and the low-order line current harmonics caused by grid voltage distortion is inherently compensated by this proposed corrective feed-forward control.

TL;DR: In this article, a coordinated control method is proposed for three-phase ac/dc hybrid microgrid power electronic interlinking unit with dual converters sharing both dc and ac links.
