With　the　continued　focus　on　the　need　to　reduce　carbon,　the　hydrogen　economy　is　advancing　rapidly.　Transporting　hydrogen　via　hydrogen　pipelines　enables　to　solve　the　problem　of　large-scale　utilization　of　hydrogen　and　the　theoretical　study　of　the　hydrogen　network　operation　could　lay　a　solid　foundation　for　its　application,　and　thus　the　operation　of　the　hydrogen　network　and　related　equipment　is　discussed　in　this　paper.　First,　in　order　to　make　up　the　deficiency　of　the　existing　theoretical　research　on　the　hydrogen　production　efficiency,　a　fine　model　for　the　dynamic　hydrogen　production　efficiency　of　electrolyzers　is　introduced,　in　which　the　effects　of　hydrogen　production　power　and　aging　on　the　hydrogen　production　efficiency　are　simultaneously　considered.　On　this　basis　and　on　the　premise　of　meeting　the　hydrogen　demand　and　the　operation　constraints　of　the　hydrogen　network　and　related　equipment,　an　optimal　operation　model　for　the　hydrogen　network　under　consideration　of　the　hydrogen　production　efficiency　characteristics　of　electrolyzers　is　presented　with　the　optimization　objective　of　minimizing　the　electricity　purchase　cost　of　the　hydrogen　network　in　one　day.　Specifically,　it　can　be　transformed　into　a　linearized　model　for　easily　getting　a　solution.　Finally,　based　on　a　20-node　hydrogen　network　in　an　industrial　park,　the　distribution　of　the　hydrogen　flow　in　a　hydrogen　network,　the　operation　strategy　of　electrolyzers　and　the　influence　of　the　capacity　of　hydrogen　storage　tanks　on　the　operating　cost　are　elaborated.　The　simulation　results　show　that　the　operation　strategy　for　the　hydrogen　network　considering　the　dynamic　hydrogen　production　efficiency　of　electrolyzers　can　reduce　the　actual　operating　cost　of　the　hydrogen　network,　and　reasonable　capacity　allocation　for　the　hydrogen　storage　tanks　is　beneficial　to　maximizing　the　benefit　of　the　hydrogen　network.　©　2023　Chinese　Society　for　Electrical　Engineering.　All　rights　reserved.
