Under　the　guidance　of　the　concept　of　low-carbon　travel,　aiming　at　the　challenges　brought　by　the　large-scale　grid　connection　of　electric　vehicles　to　the　safe　and　reliable　operation　of　the　microgrid　system,　this　paper　proposes　a　microgrid　optimization　scheduling　strategy　considering　the　access　of　electric　vehicles.　Firstly,　the　road　network　with　complex　road　conditions　is　normalized,　and　the　optimal　scheme　of　electric　vehicles　scheduling　route　is　formulated　based　on　Floyd　algorithm.　Then,　considering　the　active　network　loss　and　node　voltage　deviation　of　microgrid,　an　optimal　scheduling　model　of　microgrid　considering　unit　operation　constraints　is　established.　Finally,　based　on　the　extended　IEEE33-bus　test　system,　the　simulation　analysis　is　carried　out　to　verify　the　impact　of　network　reconfiguration　and　flexible　load　participation　in　demand　response　on　the　optimal　scheduling　of　microgrid.　The　simulation　results　show　that　this　method　is　beneficial　to　improve　the　voltage　quality　of　microgrid,　reduce　the　peak-valley　difference　of　load　curve　and　improve　the　system　operation　profit.　©　2023　IEEE.
