The　wide　application　of　communication　equipment　appears　to　increase　the　risk　of　cross-domain　attacks　on　distribution　networks＇　cyber-physical　systems　(CPSs).　Against　this　background,　the　resilience　enhancement　strategy　for　CPS　of　distribution　networks　considering　coordinated　cyber-physical　attacks　is　proposed.　First,　to　analyze　the　fault　propagation　mechanism　of　CPSs　under　cyber-physical　interactions,　a　virtual　fault　propagation　network　is　built　to　identify　the　distribution　network＇s　fault　and　non-fault　areas.　Also,　a　virtual　information　flow　network　is　proposed　to　represent　the　communication　network　and　identify　the　working　state　of　cyber　nodes.　This　proposal　uses　a　cyber-physical　coupling　constraint　to　describe　the　fault　propagation　process　between　the　distribution　and　communication　networks.　Then,　a　robust　optimization　model　under　a　tri-level　framework　of　defense-attack-defense　is　established,　in　which　the　first-level　defender　develops　the　cooperative　schemes　for　the　remote-controlled　switch　deployment　in　distribution　networks　and　the　hardening　of　communication　networks.　The　attacker　seeks　the　most　serious　coordinated　attack　mode　in　the　second　level.　Based　upon　the　estimation　of　fault　propagation　impacts,　the　defender　in　the　third　level　utilizes　the　remote-controlled　switch　action　to　reconfigure　the　distribution　network　into　multiple　microgrids　and　thus　restore　the　power　supply.　The　nested　column　constraint　generation　algorithm　is　used　to　solve　the　above　model.　Finally,　the　effectiveness　of　the　proposed　model　and　method　is　verified　through　case　studies.　©　2024　Power　System　Technology　Press.　All　rights　reserved.
