This paper proposed a time-varying gain-basedpredetermined time distributed optimization algorithm for the eco-nomic dispatch problem in micro grids.Different from the existing distributed dispatch algorithms with asymptotical exponential convergence rates,our proposed algorithm ensured that the output power of each generator converged to the global optimal point within a given time.Moreover,this predetermined time can be set in advance by the designer according to the task require-ments and was independent of the initial conditions of the system or the control parameters.By exploiting the convex optimiza-tion theory and Lyapunov stability theory,the predefined-time convergence performance was analyzed.Finally,several numerical examples wereprovided to show the effectiveness of the presented distributed predefined-time economic dispatch algorithm.
