为平缓风电场输出, 实现大规模风电并网并参与系统的频率控制, 设计了一个基于永磁同步电机的飞轮储能系统, 利用飞轮储能系统的快速充放电能力实现了风电场并网有功功率与一次频率控制. 研究了飞轮储能系统的参考功率计算方法, 根据该参考功率的变化实现储能系统充放电运行状态的转化. 在Matlab/Simulink中建立了该储能系统模型, 进行了风电场并网的有功功率及频率控制仿真, 仿真结果表明该方法可以有效地平缓风电场的有功功率输出, 参与系统的一次调频.
To gentle the output of wind farm, achieve the connection of large scale wind farm to power grid and the function of first frequency control, a flywheel energy storage system (FESS) based on permanent magnet synchronous motor is designed in this paper. The reference power calculation method of FESS when it assist wind farm with active power and primary frequency control is studied. The operation state of the FESS changes according to the change of reference power. And by controlling the grid side converter, the energy exchange between grid and storage system and unit factor operation are achieved. Space voltage vector control technology is adopted in both converters. Control models of FESS are established in Simulink, and simulation of active power and frequency control of wind farm are conducted. The result shows that this control method could effectively smooth the output of wind farm, and decreases
the frequency deviation of grid as well.
