In　recent　years,　with　the　rapid　development　of　renewable　energy,　power　energy　storage　has　become　a　bottom　neck　of　its　development,　and　superconducting　magnetic　energy　storage　(SMES)　seems　to　be　a　viable　solution.　A　topology　based　on　common　DC　voltage　bus　is　proposed　for　high　power　voltage　source　converter　(VSC)-SMES.　The　mathematical　model　of　SMES　is　constructed　and　the　detailed　control　strategy　is　derived.　According　to　the　characteristics　of　SMES,　dual　mode　switching　control　strategy　is　adopted.　Simulations　under　different　conditions　are　carried　out　with　PSIM　simulation　tool.　The　fast　response　of　SMES　and　effectiveness　of　dual-mode　switch　control　are　verified　by　simulation　waveforms　and　the　active　and　reactive　power　can　be　controlled　independently
