| Description |
Advancements have been made in the field of power electronics and particularly in energy management of microgrids. In this thesis, we present a comparison of two single-phase reactive power control strategies used to achieve a unity power factor with an energy management system in an AC microgrid. The first method measures the root-mean square of both voltage and current, and relies on principles derived from the power triangle. The second method is based on the instantaneous reactive power αβ theory normally proposed for three-phase systems. In creating a secondary imaginary orthogonal circuit, this control method can be applied to a single-phase system. The proposed control schemes were designed and validated utilizing a physics-based microgrid model. The model was used in a grid-connected mode scenario with a resistive-inductive load. Once both methods were designed and implemented in MATLAB-SIMULINK, the model behaved as expected for real power. Both control methods were nearly identical in providing reactive power compensation to create unity power factor. Some differences were observed while conducting transient-type testing, but they had a negligible impact on the overall operation of the microgrid. Subjects: energy management system; unity power factor; reactive control; real and reactive power modeling |
