摘要:
为了提高风电场参与电网一次调频的稳定性和可靠性,提出了一种考虑机组稳定性约束的风电场双层功率分配策略。结合调频风电机组的稳定域分布,分析了调频期间风速持续降低对低风速段机组稳定运行的影响。根据各台风电机组的可释放动能,以风电场出力误差最小、机组参与调频台数最少和控制模式切换次数最少为优化目标,实现了风电场中机组功率指令的优化分配,同时通过采集各机组转速对功率指令进行实时修正。在湍流风速下对不同分配策略进行仿真比较,结果表明,该文方法能够有效避免低风速段风电机组因动能释放过度而失稳退出运行。
Abstract:
In order to improve the stability and reliability of the wind farm participating in the primary frequency regulation of power grids,a double-layer power distribution strategy of the wind farm considering the stability constraints of the units is proposed. The influence of the continuous reduction of wind speed on the stable operation of low wind speed units is analyzed during the period of frequency regulation in combination with the distribution of the stability region of the wind turbine units. According to the released kinetic energy of each wind turbine,the optimal allocation of the power command of the wind turbine in the wind farm is realized by taking the optimization objectives as the minimum output error of the wind farm,the minimum number of units participating in the frequency regulation and the minimum number of control mode switching. At the same time,the power command is corrected in real time by collecting the rotation speed of each unit. Different distribution strategies are simulated and compared under the turbulent wind speed. The results show that the proposed method can effectively avoid the wind turbine in the low wind speed section from losing its stability due to the excessive release of kinetic energy.
