The　new　mode　of“wind　farm+energy　storage”has　gradually　become　the　mainstream.　Facing　the　new　power　system　with　high　proportion　of　wind　storage　system　connected　to　grid，a　multi-timescale　optimal　scheduling　strategy　of　wind-storage　cluster　power　system　with　demand　response　is　proposed.　Firstly，in　the　day-ahead　long　time　scale　stage，the　user　load　power　is　adjusted　by　price　based　demand　response，and　the　day-ahead　scheduling　plan　and　optimized　load　curve　are　obtained　with　the　goal　of　minimizing　the　net　load　power　fluctuation　and　operating　cost.　Secondly，in　the　intra-day　short　time　scale　stage，the　incentive　demand　response　and　wind-storage　systems　are　scheduled　on　the　basis　of　the　optimized　load　power.　With　the　goal　of　minimizing　the　total　dispatching　cost　of　the　power　system，the　daily　scheduling　plan　of　the　power　system　is　formulated　considering　the　maximum　limit　of　the　active　power　change　of　the　wind-storage　cluster　system.　Finally，the　improved　IEEE39-node　system　is　taken　as　an　example　to　verify　the　proposed　strategy.　As　the　results，the　proposed　strategy　can　reduce　the　curtailment　power　and　grid-connected　power　fluctuation　of　wind-storage　cluster　system.　©　2025　Science　Press.　All　rights　reserved.
