Abstract

A finite-time cascaded control is designed for grid-forming inverters to establish and support the frequency and voltage of an islanded microgrid under uncertainties. Firstly, a fast integral terminal sliding manifold is developed to attain fast tracking convergence, minimize the tracking-error, and improve the integrity of current by mitigating total harmonic distortion. Secondly, an exponential reaching law is added in the control schema to increase the robustness of the system. Lyapunov theory is employed to establish finite-time stability. Finally, simulation results demonstrate that the proposed control exhibits superior tracking accuracy, mitigates the chattering phenomenon, and enhances support for the frequency and voltage of an island microgrid compared to sliding mode control.
