A Novel Control Strategy Based on Fuzzy Logic in Islanded Microgrid

In order to correctly share active power across distributed generation (DG) units, this paper uses frequency and active power control in a microgrid consisting of two distributed generation units. The frequency recovery from the microgrid is controlled by an interval type-2 fuzzy logic control with double input, which returns the frequency oscillations in an appropriate range of standard magnitude. The fuzzy controller extends by providing multiple control levels by modifying a customizable membership function that modifies system uncertainty. The output responses for the presence and also absence of the fuzzy control are evaluated to ensure the efficiency of the suggested controller. For examining the influence of output loads on an experimental microgrid, total harmonic distortion has been recognized as a harmonic criterion. Finally, the performance of the suggested architecture is confirmed by the results of the microgrid simulation in island mode.
