A power distribution system with distributed generations can operate as a microgrid under specific conditions. A microgrid can be operated under grid-connected and islanded modes seamlessly without disrupting the loads within the microgrid. This study analyzes the intelligent control of a microgrid with a pulse-width modulation-controlled voltage source inverter. Switching patterns are generated through a fuzzy proportional-integral (PI) controller. This study aims to develop a fuzzy-PI controller and compare its performance with that of a PI controller in controlling the voltage and frequency of a microgrid under disturbances in a Matlab/Simulink environment. Results show that the fuzzy-PI controller has higher capability, precision, and robustness than the PI controller in quickly restoring and stabilizing the microgrid. A simulation experiment is also performed to verify the greater validity and effectiveness of the microgrid equipped with the fuzzy-PI controller than with the PI controller. The developed fuzzy-PI controller can reduce the total harmonic distortion by 0.46%.

W artykule analizowano inteligentne sterowanie mikrosiecią z wykorzystaniem przekształtnika sterowanego metodą modulacji szerokości impulsu. Jako sterownik wykorzystano proporcjonalno całkujący układ z logika rozmytą. Zbadano pracę układu w sieci z zakłóceniami. Stwierdzono znaczące przewagi kontrolera pracującego z logika rozmytą w porównaniu do układów konwencjonalnvch.
