An Enhanced Microgrid Load Sharing by using PI & Fuzzy Controllers

The main task of autonomous microgrids is to share the load demand using multiple distributed generation (DG) units. In order to realize satisfied power sharing without the communication between DG units. This paper proposes a fuzzy based enhanced control strategy to estimate the reactive power control error through injecting small real power disturbances for improving the accuracy. An accurate reactive power sharing achieves in the proposed compensation method at the steady state. Simulation results are carried out by MATLAB Software.
