Small signal stability analysis and control strategies are well provided for conventional power systems. Still, in
inverter-based microgrids, it is necessary to determine the model features and control specific oscillation modes. In this
paper, inverter-based standalone microgrid performance modelling, including voltage and current control, has been
developed. This model has inverter control loop details but does not provide switching performance. A simple adaptive
controller controls the microgrid voltage and current, with only three parameters, including two negatively stable feedbacks
and positive unstable feedback. Advantages of this controller over a Proportional Integral Derivative (PID) controller
include proper adaptation to system changes, flexibility in setting up, and a robust deal with sudden changes in the system.
Finally, by making drastic changes in the operation of a sample microgrid, such as loading and short circuit faults, we prove
the effectiveness of the proposed adaptive control scheme in improving the stability and restoration of operation after the
occurrence of a transient fault in the microgrid.
