Event-triggered secondary frequency control based on fixed-time consensus algorithm for islanded microgrid
For its poor anti-interference ability,the traditional consensus algorithm of microgrids cannot guarantee the transient time;controller periodic sampling causes a large amount of data redundancy.Therefore,an event-triggered mechanism based on fixed-time consensus algorithm was proposed to achieve output frequency recovery and proportional allocation of active power.The proposed control strategy improves the convergence speed of the system,achieves system stability within a fixed time,and reduces dependence on the initial state of the system.At the same time,introducing an event-triggered mechanism saves communication resources by reducing the transmission of sampling information.The stability of the proposed control strategy was proved by the Lyapunov theory.The effectiveness of the proposed control strategy was confirmed by the simulation results obtained form Matlab/Simulink.
