There　are　inevitable　multiple　uncertainties　in　multi-energy　microgrid.　In　order　to　formulate　a　reasonable　dispatching　scheme　under　the　uncertainties,　this　paper　proposed　an　affine-model　predictive　control　optimal　dispatching　method　for　multi-energy　microgrid.　Firstly,　the　uncertainties　in　multi-energy　microgrid　are　represented　by　affine　algorithm,　and　the　interval　expansion　problem　is　solved　by　using　the　correlation　between　affine　variables.　Further,　an　affine　optimal　dispatching　model　of　multi-energy　microgrid　is　constructed　to　ensure　the　economy　and　decrease　the　conservatism　of　the　dispatching　scheme.　Finally,　the　model　predictive　control　method　is　used　to　update　the　predictive　information,　and　the　affine　optimal　dispatching　model　of　multi-energy　microgrid　is　solved　by　rolling.　The　simulation　results　show　that　the　proposed　method　can　ensure　the　economy　and　decrease　the　conservatism　of　the　dispatching　scheme.　Under　the　premise　of　ensuring　the　economic　operation　of　multi-energy　microgrid,　it　can　effectively　deal　with　the　impact　of　uncertainties　and　provide　a　reasonable　optimal　dispatching　scheme.　©　2023　IEEE.
