Priority list method for active power cutback control in a wind farm

This paper proposes an optimized dispatch strategy for active power cutback control in a wind farm. The strategy is considered as the supplement of the control strategy of the active power control system for wind farm clusters. Based on the priority list method, the control strategy is designed to realize the dynamic control sequence of wind turbines considering regulation capacity, regulation speed and response time. In this control approach, wind farm is supposed to respond to dispatch command from centre control station in an optimal and economical way. The strategy achieves the control target of wind farm output constraint by pitch angle control and rotor speed control instead of cutting off turbines. At last, the feasibility and validity of the presented strategy are tested on a wind power system.
