【摘要】：针对集群风电场分别接入电网不同外送断面的特点,提出了调峰约束下考虑发电优先级的风电有功控制策略。所提控制策略按照弃风的严重程度,为各风电场设定不同发电优先级,结合电网消纳能力、风电场的装机容量和发电能力等因素计算各风电场的有功指令。指令控制周期内调峰约束与断面约束的配合、调峰目标值校验和强制触发策略的设计既保证了充分利用电网消纳能力和外送断面容量,又确保了调峰约束和断面约束的安全极限;高优先级风电场的钳位控制策略有效避免了电网消纳能力快速变化时低优先级风电场的有功大幅波动。冀北电网的实际运行结果证明了所提控制策略的有效性。
[Abstract]:A wind power active control strategy considering the priority of power generation is proposed for the cluster wind farm . The control strategy is to set different power generation priorities for each wind farm according to the severity of the abandoned wind . The design of the peak target value and the cross - section constraint can be used to ensure the safety limit of the peak regulation and the cross - section constraint . The power regulation control strategy of the high - priority wind farm effectively avoids the active power fluctuation of the low - priority wind farm when the power distribution capacity of the grid is rapidly changed . The actual operation results of the northern Hebei power grid demonstrate the effectiveness of the proposed control strategy .
