Existing distributed secondary control for microgrids struggles to balance voltage/frequency restoration speed and proportional active power sharing accuracy under switching topologies, restricting practical application. To address this, a novel distributed fixed-time secondary controller is proposed to achieve voltage/frequency consensus, proportional active power sharing and topology adaptability for distributed generation units. Lyapunov theory proves asymptotic stability under switching topologies, and bi-limit homogeneity theory yields sufficient conditions for fixed-time stability. Hardware-in-the-loop experiments under typical conditions verify its effectiveness and advantages.
