Abstract: This paper details a simulation model for a hybrid distribution transformer featuring the proposed control system for harmonic distortion compensation. The developed model includes an active power filter that utilizes both high-pass and band-pass filters. The study examines the performance of the control system for active compensation of consumer current harmonics in a power grid with electric vehicle charging stations. Current harmonic spectra and distortion levels, characterized by the total harmonic distortion, served as a performance metric. The simulation was conducted using the SimPowerSystems toolbox within the MATLAB/Simulink environment. The findings indicate that the hybrid distribution transformer with the proposed active power filter control system significantly enhances power quality for the end-consumer compared to a conventional power transformer. The current total harmonic distortion level is reduced threefold. The total harmonic distortion surge caused by the connection of additional non-linear loads is effectively suppressed. Furthermore, the current harmonics showed a substantial reduction: the 5th harmonic decreased by a factor of eight, while the 7th harmonic dropped by a factor of three.
