In　this　paper,　distributed　finite-time　trigger-based　secondary　frequency　and　active　power　control　for　AC　microgrids　(MGs)　is　proposed　to　achieve　frequency　restoration　and　active　power　sharing.　Considering　the　limited　communication　bandwidth　of　distributed　generators　(DGs),　an　event-triggered　method　is　introduced　using　Lyapunov　theory.　The　MATLAB/Simulink　simulation　results　of　an　AC　MG　shows　that　the　proposed　secondary　controller　can　effectively　perform　frequency　restoration　and　share　active　power　among　DGs　according　to　the　power　ratings.　©　2023　IEEE.
