With　the　large-scale　grid　integration　of　wind　power,　the　inherent　space-time　characteristics　of　wind　power　and　the　transmission　congestion　seriously　restrict　the　consumption　of　wind　power　and　the　development　of　demand.　In　order　to　improve　the　wind　power　accommodation　and　load　acceptance　level,　the　joint　planning　including　the　wind　power　installed　capacity　and　location,　the　transmission　network　expansion,　and　energy　storage　system　locating　and　sizing　is　considered.　The　generation-side　operation　process　and　the　charging-discharging　strategy　of　energy　storage　systems　are　also　involved.　The　source-network-storage　joint　planning　model　is　established　with　the　goal　of　minimizing　the　cost　of　the　transmission　network　expansion,　the　construction　and　operation　of　energy　storage　systems,　the　conventional　units＇　operation,　the　wind　curtailment,　and　the　heavy-load　penalty.　Furthermore,　the　energy　storage　system　planning　&　operation　constraints,　the　heavy-load　operation　constraints　and　the　quadratic　generation　cost　function　are　linearized　in　the　MILP　model.　Through　the　Wood&Wollenberg　6-bus　system,　the　IEEE　RTS-24　test　system,　and　the　modified　IEEE　118-bus　system　as　the　test　systems,　the　joint　planning　schemes　under　multiple　scenarios　are　compared　and　analyzed.　The　results　show　that　the　proposed　planning　model　can　effectively　improve　the　load　acceptance　capability　and　wind　power　integration　level.
