Abstract: Spacesolarpowerstation（SSPS）isaspacesystemcollectingandtransformingsolarenergyintomicrowaveorlaserintheorbitandwirelesslytransmittingthepowertothegroundstation,wherethepowerischangedintoelectricity.Solarconcentrationisamethodofcollectingspacesolarenergy,andisappliedto  manySSPSconcepts.AfterreviewingtheprogressofthesolarconcentratingSSPS,andsummarizingtheconceptsandtechnologiesofsolarconcentrationrelatedtotheSSPS,thesolarconcentrationisdividedintofourmodescorrespondingtothreelevels,andboththeadvantagesanddisadvantagesofeachmodewereanalyzed.ThedevelopmentofthesolarconcentratingSSPSwasproposed.
