Abstract
With the increasing integration of distributed generation into the grid, the secondary control of microgrids has become a prominent research focus in this field. However, distributed secondary control in microgrids is subject to constraints from external factors, necessitating both rapid response speed and a reliable communication network. This paper proposes a distributed practical prescribed-time secondary control method aimed at achieving microgrid stability. A key feature of this approach is that the convergence time can be predefined and remains independent of both design parameters and initial conditions. Furthermore, an event-triggered communication strategy is adopted to enhance the efficiency of communication resource utilization within the microgrid. The criterion for achieving practical prescribed-time consensus in the microgrid is established using Lyapunov stability theory. Moreover, the proposed distributed secondary control method is proven to exclude Zeno behavior. Finally, the effectiveness and superiority of the proposed method are demonstrated through case analyses and simulation results.
