High Order Voltage and Current Harmonic Mitigation Using the Modular Multilevel Converter STATCOM

Due to the increase of power electronic-based loads, the maintenance of high power quality poses a challenge in modern power systems. To limit the total harmonic distortion in the line voltage and currents at the point of the common coupling (PCC), active power filters are commonly employed. This paper investigates the use of the multilevel...
