摘　　要：在含构网型(GFM)变流器、跟网型(GFL)变流器及同步机发电3种异构电源的系统中,变流器控制参数是影响系统小信号稳定性的重要因素之一。对变流器的控制参数进行优化设计,可以提高异构电源系统的稳定性。首先,建立了系统的小信号模型,并利用各个控制参数变化时特征值的变化规律确定各个控制参数的优化范围。然后,利用灰狼算法对变流器控制参数进行优化设计。最后,通过仿真对比参数优化前后系统的特征值分布,验证了参数优化的有效性。For systems with three heterogeneous power sources including GFM converter,GFL converter,and synchronous machine,changes in converter control parameters can have an impact on the small signal stability of the system.In order to improve the stability of heterogeneous power systems including GFM converter,the control parameters of the converters are optimized and designed.Firstly,a small signal model of the system is established,and the optimization range of each control parameter is determined using the variation law of characteristic values when each control parameter changes.Then,the grey wolf algorithm is used to further optimize the control parameters of the converter.Finally,the distribution of system characteristic values before and after parameter optimization is compared through simulation to verify the effectiveness of parameter optimization.
