The　physical　information　system　model　improves　the　control　accuracy　of　microgrids　(MGs).　However,　it　remains　susceptible　to　denial-of-service　(DoS)　attacks　targeting　distributed　generators　(DGs),　which　may　lead　to　control　failures.　This　paper　presents　a　distributed　event-triggered　control　mechanism　designed　to　mitigate　the　impact　of　DoS　attacks　while　ensuring　accurate　current　sharing　and　voltage　restoration.　The　proposed　approach　enhances　system　resilience　and　reduces　communication　frequency.　Using　Lyapunov　stability　theory,　we　establish　that　the　system　maintains　asymptotic　stability　under　DoS　attack　conditions.　Finally,　simulation　experiments　conducted　in　the　Matlab/Simulink　environment　validate　the　effectiveness　of　the　proposed　method.　©　2025　IEEE.
