The　current　planning　and　construction　of　offshore　wind　farm　rarely　considers　the　construction　time　sequence,　which　mostly　belongs　to　static　single-stage　planning　and　is　easily　lead　to　the　lack　of　effective　connection　between　the　initial　planning　scheme　and　the　operation　at　middle　and　late　stages,　for　which,　a　multi-stage　planning　scheme　for　offshore　wind　farm　considering　wind　power　accommodation　level　is　proposed.　The　day-ahead　market　trading　model　with　the　lowest　electricity　purchase　cost　as　its　objective　is　established　to　evaluate　the　maximum　accommodation　level　of　power　grid　to　offshore　wind　power,　and　the　maximum　accom-modation　levels　of　regional　power　grid　to　offshore　wind　power　are　obtained　under　different　load　levels　in　the　future　years.　On　this　basis,　the　planning　period　is　divided　into　several　stages,　and　a　multi-stage　planning　model　of　offshore　wind　farm　with　the　maximum　net　revenue　of　wind　farm　as　its　objective　is　built,　which　takes　the　investment　year,　number,　location　and　the　belonging　investment　stage　of　wind　turbines　as　its　optimi-zation　variables.　Examples　verify　the　effectiveness　of　multi-stage　planning　model　in　improving　economic　bene-fit　of　offshore　wind　farm　compared　with　single-stage　planning　model.　©　2022,　Electric　Power　Automation　Equipment　Press.　All　right　reserved.
