A　grid-forming　converter　(GFM)　controls　power　output　by　adjusting　the　phase　angle　and　amplitude　of　its　output　voltage,　providing　voltage　and　frequency　support　to　the　power　system　and　effectively　enhancing　system　stability.　However,　it　has　limitations　in　current　control,　influencing　the　current　only　indirectly　through　voltage　regulation,　which　results　in　weaker　control　over　current　waveform　quality.　In　the　context　of　a　large　number　of　renewable　energy　generation　units　being　connected　to　the　grid,　harmonics　in　the　grid　voltage　can　lead　to　excessively　high　harmonic　content　in　the　grid　current,　exceeding　standard　limits　and　causing　oscillations.　To　solve　this　problem,　this　paper　proposes　a　control　strategy　of　harmonic　voltage　feedforward　compensation　to　suppress　grid　current　distortion.　The　proposed　control　strategy　extracts　harmonic　voltages　from　the　output　port　of　the　GFM　converter　through　a　harmonic　extraction　module,　processes　them　via　a　feedforward　factor,　and　introduces　the　resulting　signals　into　the　converter＇s　control　loop　as　feedforward　compensation　terms.　This　allows　the　converter＇s　output　voltage　to　compensate　for　the　harmonic　components　in　the　grid,　achieving　the　improvement　of　grid　current　and　reducing　the　total　harmonic　distortion　(THD)　value.　The　effectiveness　of　the　proposed　control　strategy　is　verified　by　simulation　results.
