To address the issues of poor frequency regulation performance and torsional oscillations in traditional wind farm primary frequency regulation algorithms
this paper proposes a coordinated control algorithm for wind power primary frequency regulation considering dynamic classification of unit spinning reserves. First
according to the safe speed operation requirements
power regulation capability
and releasable rotating energy storage capacity
the wind turbines in the wind farm are divided into four categories
namely
priority spinning reserve units
general spinning reserve units
weak spinning reserve units
and non-spinning reserve units. Second
the primary frequency regulation capability of the priority spinning reserve units under different power limit conditions is obtained. For these priority units
a wind farm primary frequency regulation control algorithm based on frequency regulation capability is adopted. Finally
the proposed algorithm is verified on a simulation platform. The experimental results show that the proposed algorithm can meet the primary frequency regulation requirements of the power grid
achieving better frequency regulation performance than traditional algorithms
and significantly reduce shaft oscillations in the wind turbine units.
