Abstract

High dynamical behavior and performance are required to maintain stable islanded microgrid operation based on inverters. However, this is strongly conditioned by the implemented control strategy as well as the characteristic parameters of the islanded microgrids. This paper investigates the influence of the controller characteristics and the microgrid parameters, on the small-signal stability of islanded microgrid. It makes the coupling between both factors in order to carry out the local stability model depending on the microgrid parameters. The islanded microgrid fed by a single inverter-based source whose control is based on inner control loops approach, is considered. The influence of each parameter is examined by analyzing the dynamical behavior of the eigenvalues in the complex plane, and the dynamical performance of the controller, with Matlab/Simulink. Accordingly, the modelling and simulation results obtained, showed that the effects of these parameters help identify and define the limits of local stability of islanded microgrids.
