Droop　control　has　the　advantages　of　realizing　active　power　sharing　and　reliable　operation　of　each　distributed　generators　(DG)　in　AC　microgrids.　However,　the　nonactive　power　generated　by　reactive　load,　nonlinear　load　and　single-phase　load　cannot　be　shared　among　DGs　under　droop　control,　which　may　lead　to　overloading　of　certain　inverters　or　even　cause　system　paralysis.　This　paper　proposes　a　dual-frequency-droop　based　nonactive　power　sharing　control　strategy　for　AC　microgrids,　which　achieves　active　power　sharing　through　active　power-fundamental　frequency　droop,　and　achieves　nonactive　power　sharing　through　nonactive　power-injected　harmonic　frequency　droop.　A　specific　harmonic　signal　is　deliberately　injected　by　each　DG　to　adaptively　regulate　the　virtual　impedance　to　realize　nonactive　power　sharing.　Simulation　and　experimental　results　have　been　provided　to　verify　the　effectiveness　of　the　proposed　strategy.　©　2025　IEEE.
