In　recent　years,　with　the　development　of　distributed　generation(DG)　technologies,　a　large　number　of　DG　are　connected　to　the　distribution　network,　however,　the　output　of　DG　is　intermittent　and　random.　Considering　the　timing　characteristics　of　DG　and　loads,　this　paper　establishes　a　generalized　power　optimal　configuration　model　of　energy　internet　which　takes　power　purchasing　cost,　investment　cost,　operation　and　maintenance　cost,　network　loss　cost,　fuel　cost　and　government　subsidies　comprehensive　cost　as　the　objective　functions.　The　invasive　weed　optimization(IWO)　based　on　cloud　model　is　used　to　solve　the　model.　The　model　and　the　algorithm　proposed　in　this　paper　are　simulated　by　IEEE　13　nodes　to　verify　its　validity.　©　2018　IEEE.
