摘　　要：Dear Editor,The existing control schemes for microgrids(MGs)face challenges in effectively addressing plugging in/out operations under uncertain power lines and faults.To tackle this issue,this letter proposes a novel scalable fault-tolerant control(FTC)strategy for DC MGs.By developing a structured Lyapunov matrix(SLM),a decoupled FTC method is introduced to mitigate the adverse effects of uncertain lines and nonuniform faults.Moreover,global stability is ensured by deriving local rules expressed as linear matrix inequalities(LMIs)that solely depend on local parameters.Each new distributed generation unit(DGU)introduces only one additional condition of this nature,allowing the stability rules to scale with topology changes.Finally,the effectiveness of the proposed scheme is illustrated through simulations conducted using the MATLAB/SimPowerSystems toolbox.
