Abstract：Toaddress therapid response requirements of virtual power plant economicdispatchand the prevalentneglectof correlation between leader node selectionandconvergence eficiencyin existingresearch，this study proposedatwo-stage improved consensus-based distributed economicdispatch strategy foraccelerating algorithmconvergence.It introducedanimproved K-shell method and a two-layer neighbor optimization term to establish the K* leader node selection method and a twolayerneighbor-optimizedconsensus variableupdate formula.Simulationsandanalyses wereconductedundertwocommunicationtopologies.Results demonstrate that the proposed strategy improves convergence eficiency byapproximately 54% compared with benchmark algorithmsunderboth topologies.Itexhibitssuperior node failurerobustness，load mutationconvergence，plug-and-playcapability，betereconomicperformance，anddistributedadvantages.Theselectedconvergencecoefficient ε proves reasonable，while tolerance μ requires dynamic adjustment based on dispatch accuracy requirements. The twostageimproved strategyefectivelyenhances convergence eficiencywhilemaintaining plug-and-playcapability，economicbenefits，distributedcharacteristics，androbustness，making itsuitableforvirtualpowerplanteconomicdispatch scenarios.
