Reduced-order model of AC microgrid for stability analysis and adjustment of droop control
TL;DR: Simutation results are presented to show that the proposed reduced-order small-signal model of microgrid considering an arbitrary number of parallel-connected inverters has good accuracy and can be used as tool for stability analysis and adjustment of droop control coefficients of the inverters.

Frequency adaptive proportional + multi-resonant output voltage control strategy for parallel operating distributed generation units
TL;DR: In this article, a multi-loop control strategy for parallel distributed generation (DG) units in standalone mode of operation is presented, where an Adaptive Proportional plus Multi Resonant (Adaptive P+MR) controller is designed for the voltage control loop and a simple proportional regulator is used for the inner current loop.

Wireless-Control Strategy for Parallel Operation of Distributed-Generation Inverters
TL;DR: Adapt virtual output impedance is proposed in order to achieve a proper reactive power sharing regardless of the line impedance unbalances and can be properly shared due to the addition of a current harmonic loop in the control strategy.
