A decentralized multi-framed droop-controller for improving harmonic power sharing in an islanded microgrid
TL;DR: In this paper, a multi-framed droop controller is proposed to improve the harmonic power sharing without deteriorating voltage total harmonic distortion (VTHD) by adjusting the equivalent impedance, where the inherent output impedance of inverter is reduced by multi-frequency resonant (R) controllers in dq frame whereas the influence of the mismatching impedance is minored by moving-average-filtered complex impedance in αβ frame.
