The system inertia and the primary frequency modulation capacity are decreased by the reduction of the traditional conventional unit start-up capacity as the rapid development of wind power. The active power disturbance is increased after system frequency change rate. It is indispensable to study the inertia compensation and primary frequency modulation methods provided by wind turbines. A fuzzy adaptive virtual frequency modulation control strategy for wind power is proposed by analyzing the frequency modulation characteristics of wind turbines. Firstly, the mathematical model of wind power participation in frequency modulation and the frequency response model of the high proportion system is established. Secondly, analyzing the frequency change characteristics of the system after the disturbance, and establishing the wind power fuzzy control rules for the shortcomings of insufficient fixed parameter control, the stability of the fuzzy control rule parameters are analyzed by the root locus method. Finally, the effectiveness of the fuzzy control is verified by simulation, and the system stability is improved. |
