Wind power output has the characteristics of uncertainty and fluctuation

so the input power fluctuation caused by the wind power with high proportion brings bigger challenges to multi-area load frequency control. Considering the impact of prediction error of wind power on the load frequency control and the impact of open communication environment in the future on area control error transmission

a robust control strategy of load frequency based on event triggering communication is proposed to maintain the frequency stability of power system with wind power and reduce the network communication as much as possible. The load frequency control of a typical two-area system with wind power is taken as the simulation case. The simulation results show that compared with traditional proportional-integral controller

the robust controller based on event triggering communication can not only effectively guarantee l2 gain performance of frequency output under the fluctuation of wind power

but also reduce the communication times in the steady state

which has good frequency control performance.
