Under　the　background　of　the　implementation　of　＂dual　carbon＂　policy,　the　importance　of　developing　renewable　energy　such　as　offshore　wind　power　has　been　increasing.　However,　the　volatility　of　wind　power　brings　about　safety　problems　to　the　system　operation.　Therefore,　this　paper　proposes　an　offshore　wind　power-multiple　energy　storage　system　that　takes　into　account　gas-solid　two-phase　hydrogen　storage　in　combination　with　various　energy　storage　technologies,　and　the　requirements　of　safe　operation　of　offshore　wind　power　system　are　met　through　allocation　of　energy　storage　capacity.　Firstly,　the　model　of　offshore　wind　powermultiple　energy　storage　system　is　constructed,　and　the　system　structure　and　the　energy　flow　are　described.　Secondly,　the　hydrogen　storage　system,　which　includes　gas-solid　two-phase　hydrogen　storage,　is　introduced,　and　the　principle　of　solid-phase　hydrogen　storage　is　expounded.　Then,　an　optimal　allocation　model　of　offshore　wind　power-multiple　energy　storage　system　is　developed.　Finally,　a　simulation　is　carried　out　with　typical　weekly　operation　data,　and　the　results　show　that　the　proposed　system　can　improve　the　safety　and　economy　of　the　offshore　wind　power　systems.　©　2024　Automation　of　Electric　Power　Systems　Press.　All　rights　reserved.
