Aiming　at　the　problems　of　collaborative　optimal　dispatching　of　WMCB(Watershed-type　wind-solar-water　Multi-energy　Complementary　Bases)　for　clean　energy　consumption,　the　related　researches　on　optimal　dispatching　mode　and　mechanism　are　summarized　and　prospected.　The　problems　mainly　include　space-time　multi-scale　correlation　analysis　of　clean　energy,　multi-energy　complementary　characteristics,　efficient　absorption　and　safety　control　of　large-scale　and　multi-type　clean　energy.　Firstly,　the　development　status　of　WMCB　is　analyzed,　and　the　bottlenecks　of　its　collaborative　optimal　dispatching　are　summarized.　Then,　the　research　status　of　WMCB　is　summarized　from　the　aspects　of　space-time　multi-scale　complementary　characteristics,　collaborative　optimal　dispatching　mode　and　mechanism.　Finally,　the　solutions　of　the　problems　related　to　the　collaborative　optimal　dispatching　of　WMCB　are　explored,　in　order　to　promote　the　construction　and　development　of　WMCB　and　the　complementary　development　and　efficient　absorption　of　large-scale　clean　energy.　©　2019,　Electric　Power　Automation　Equipment　Press.　All　right　reserved.
