To compensate for the frequency and voltage deviation caused by droop control, a fixed-time distributed secondary coordination control scheme is proposed to restore the frequency and voltage to their nominal values and achieve the desired active power sharing property. The proposed scheme can achieve the secondary control objectives within a fixed-time, which is independent of the initial conditions. This advantage makes it possible to off-line predesign the settling time according to task requirement. The stability of the proposed secondary control scheme is rigorously proved by applying the fixed-time Lyapunov stability theory. Finally, results of the simulation with Matlab/Simulink verify the effectiveness of the proposed distributed fixed-time secondary control scheme.
