Fixed-time leader-follower consensus based secondary voltage control for microgrid under directed communication graph*

This paper presents a fixed-time leader-follower consensus based secondary voltage controller for microgrid under directed communication network. First, microgrid model consisting of inverter based distributed generator, network model and load model is established. Next, secondary voltage control problem of the studied microgrid is converted into leader-follower consensus problem of single integrator multi-agent system. Then, we develop a fixed-time leader-follower consensus control protocol for secondary voltage restoration. Finally, simulation results verify the effectiveness of the presented control strategy.
