Multifunctional DGs and active power filters have become a mature technology in recent years, so in this paper,an optimized current control method for a multilevel converter is proposed. The control method will overcomeharmonic current tracking inefficiency of previous control methods in online harmonic compensation applicationsin microgrids. This control method is applicable for grid-connected inverter-based multi-functionalDistributed Generation (DG) converters. It could also be used in active power filter applications which need highspeedreference tracking ability. Having the advantages of current control methods like hysteresis band control,proportional-integral (PI) and proportional-resonant (PR) control methods, the proposed approach overcomesdisadvantages of these methods especially in harmonic reference tracking as it will be discussed in detail. Themain advantages of this method are the simplicity of implementation, calculation delay compensation and itsfast response to changes. The power electronic circuit, operating principles, two-horizon predicted switchingstates of multilevel inverter, experimental results and applications of this control method will be discussed in thepaper. For studying the feasibility of the control method, an experimental prototype is tested in a microgridplatform.
