Power Flow Control in Autonomous Micro-grid Operation Using Ants Colony Optimization Under Variable Load Conditions

An iterative adaptive virtual impedance loop for reactive power sharing in islanded meshed microgrids

“…Virtual impedance-based controllers have been presented in [21,22]. In [23] an Adaptive Virtual Impedance (AVI) based on the integration of the voltage drop between different distributed generators is proposed. In [24] the authors introduced a proper inductance in order to improve the reactive power sharing by estimating the feeder impedances.…”
