Power Quality Device for Future Household Systems with Fast Electric Vehicle Charging Station

This paper investigates on power quality improvement of Smart residential buildings with Electric vehicle charging station. A multilevel Transformerless Hybrid Series Active Filter (THSeAF) is proposed to address power quality issues related to both current and voltage. The proposed configuration assists integration of renewable energy sources to ensure a sustainable supply. The controller is based on a two separated single-phase proportional plus resonant (PR) regulator to prevent current harmonic distortions of various non-linear loads to flow into the utility. The proposed topology is able to instantly correct the power factor as well as cleaning the grid´s current, while protecting consumers from voltage disturbances, sags, and swells during a grid perturbation. Aspects of harmonic compensation and voltage restoration for a 120/240V residential system are analyzed along with the proposed solution to overcome power quality issues.
