Distributed robust adaptive finite-time voltage control for microgrids with uncertainty
Consensus based distributed robust adaptive finite-time secondary voltage control is designed for inverter-based islanded AC microgrids. The design combines decentralized local states information with the states of the neighboring distributed generators with directed communication topology. Robust control algorithms are used locally for each distributed generator to deal with uncertainty. Lyapunov and terminal sliding mode theory uses to guarantee that the proposed distributed control design can restore voltage to the reference value in finite-time. Analysis shows that the finite-time robust consensus can force the voltage of the distributed generators to reach the designed terminal sliding surface in finite-time and remain there. The proposed distributed secondary controller does not require a priori knowledge of the nonlinear dynamical model and uncertainty associated with microgrids.
