Reactive power compensation by modular multilevel flying capacitor converter-based STATCOM using PS-PWM

Abstract

This paper presents a simulation study into the implementation of a modular multi-level flying capacitor converter as a STATCOM. The converter modulation scheme applied is based on Phase Shifted PWM and the two scenarios which require compensation are investigated to verify this topology. The two scenarios are PCC voltage regulation through reactive power compensation and power oscillation damping through reactive current compensation. Simulation results verify the performance of the chosen topology
