Recent　trends　in　climate　change　have　led　to　more　frequent　extreme　weather　events,　such　as　typhoons　and　wildfires.　These　events　pose　significant　risks　to　power　grids,　especially　as　we　increasingly　rely　on　renewable　energy　sources　in　the　future.　To　address　this,　there　＇s　a　growing　need　for　strategies　ensuring　that　grids　can　quickly　recover　from　outages　caused　by　high　impact　low　possibility　(HILP)　events.　Currently,　grids　use　energy　storage　to　maximize　economic　benefits,　but　during　disasters,　this　might　not　suffice　to　meet　high　demand,　worsening　the　impact　of　outages.　This　paper　suggests　using　energy　storage　systems　like　battery　energy　storage　systems　(BESS)　and　hydrogen　storage　systems　(HSS)　to　proactively　store　energy,　improving　grid　resilience　by　maintaining　a　minimum　charge　level.　Through　simulations　on　an　IEEE　123　-bus　system　with　variable　energy　sources　such　as　photovoltaics　(PVs),　wind　turbines　(WTs),　and　storage,　the　simulation　results　show　that　the　proposed　variabletype　minimum　state　of　charge　(SOC)　incurs　an　operating　cost　loss　of　2.5　%　to　2.8　%　compared　to　the　fixed-type　minimum　SOC,　but　provides　a　power　supply　capacity　improvement　of　11.43　%　to　18.53　%.
