title = "Power Sharing Stabilization by Fractional-Order Control in Islanded Microgrids",
abstract = "In islanded microgrids (MGs), power-sharing dynamics constitute the low-frequency dominant modes that directly affect the overall MG stability. The conventional droop is known to have a tradeoff between stability margin and fast/accurate power sharing. In this paper, the fractional-order derivative (FOD) droop controller is proposed to improve the power-sharing dynamics without affecting the steady-state power-sharing accuracy. FOD terms are added to the frequency and voltage loops of the conventional droop controller to add extra degrees of freedom. The suggested controller is tested and compared with the well-known integer-order derivative (IOD) droop on a stability benchmark three DG system. The proposed controller's fractional orders are enough to achieve better dynamic performance than the IOD droop at the same controller gains. Another case study is investigated where the proposed controller is used to reduce the transient behavior of circulating current for converters connected to the same AC bus, which again shows the superiority of the proposed controller over the IOD droop.",
