As　a　new　form　of　energy　supply　that　integrates　energy　charging　and　renewable　energy　consumption,　electric　hydrogen　charging　stations　have　a　broad　prospect　in　realizing　clean　energy.　However,　safety　concerns　have　prevented　further　commercialization.　Therefore,　the　safe　operation　strategy　of　an　electric-hydrogen　charging　station　with　a　gas-solid　hydrogen　storage　system　is　proposed　in　this　paper.　The　risk　of　hydrogen　energy　utilization　is　reduced　by　changing　the　form　of　hydrogen　storage.　First,　considering　the　interaction　force　between　hydrogen　atoms,　a　non-ideal　gas　pressure　formula　based　on　compression　factor　is　proposed　to　accurately　describe　the　nonlinear　pressure　growth　in　hydrogen　storage　tank.　Then,　the　TNT　equivalent　method　and　half-lethal　range　are　introduced　to　quantify　the　risk　of　hydrogen　storage　tanks.　Safety　constraints　and　quantitative　control　indexes　are　constructed　to　provide　the　optimization　model＇s　safety　boundaries　and　decision-making　direction.　Finally,　the　original　metal　hydrogen　storage　model　is　approximated　by　the　hypothesis,　and　the　hydrogen　form　transformation　equation　is　constructed　from　the　perspective　of　the　power　grid.　The　case　study　shows　that　when　the　metal　hydrogen　storage　amount　accounts　for　20%~30%　of　the　total　hydrogen　storage,　the　optimal　safe　running　effect　of　the　electricity　-　hydrogen　charging　station　is　achieved.　©2023　Chin.Soc.for　Elec.Eng.
