With the substantial increase of wind power in the proportion of power grid

the proportion of traditional synchronous generator sets is decreased

the inertia of the system is decreased and the ability to resist the risk of disturbance failure is reduced. In order to improve frequency stability of wind power system with high proportion

a kind of adaptive virtual inertia and frequency modulation parameter compensation strategy based on fuzzy control is proposed. Firstly

the influence of different proportions of wind power on frequency change characteristics under disturbance faults is analyzed. The mathematical model of wind turbines participating in frequency modulation and a comprehensive frequency response model of high proportion wind power systems is set up. Then

in view of inefficiency of the fan fixed virtual inertia control in the frequency recovery process

the fuzzy adaptive virtual inertia and frequency modulation parameter compensation scheme is set up. Finally

the effectiveness of wind power virtual inertia adaptive fuzzy control in improving system frequency stability is verified by the simulation example.
