Renewable　energy　has　been　vigorously　developed　in　recent　years.　However,　considering　the　characteristics　of　intermittence　and　stochastic　volatility,　it　will　be　hard　to　schedule　the　smart　grid　with　renewable　energy　accessing.　Reasonable　optimized　dispatching　can　consume　more　renewable　energy,　because　the　development　of　pumped　storage　and　demand　response　brings　more　flexibility　to　optimal　dispatch　of　power　system.　Therefore,　an　optimal　dispatching　model　for　power　system　containing　various　renewable　energy　is　proposed　in　this　paper.　The　impact　of　pumped　storage　and　demand　response　on　the　renewable　energy　consumption　is　also　included.　With　the　economic　efficiency　as　objective　function,　the　established　shortterm　optimal　dispatching　model　is　combined　with　the　interaction　of　demand　response　and　the　hydropower　model　with　pumped　storage.　Finally,　the　case　study　is　performed　based　on　a　63-unit　test　system,　and　results　verify　the　effectiveness　and　superiority　of　the　proposed　model.　©　2019　IEEE.
