随着构网变流器在微电网中应用的增长,其对微电网暂态稳定的影响受到了广泛关注。不同于单机无穷大系统,孤岛并联构网变流器系统的频率和功角差相互耦合,暂态响应特性更为复杂。为精准分析孤岛并联构网变流器系统的暂态响应,文中基于功角耦合运动方程建立双机频率和功角差的三阶暂态同步模型,并且分析了双机出力差异和下垂系数对于暂态稳定的影响特征。为揭示出力和下垂系数对于暂态稳定的耦合机理,对双机系统进行等效同步功率分析
并且提出一种基于构网变流器出力的自适应下垂系数优化策略,可以根据出力差异自适应提升双机系统的等效同步功率
进而提升系统暂态稳定性。最后,采用实时仿真验证了三阶暂态模型的正确性和所提控制策略的有效性。
With the increasing application of grid-forming (GFM) converters in the microgrid
the effects of GFM converters on the transient stability of the microgrid have received extensive attentions. Different from the single-machine infinite bus system
the frequency and power angle of the islanded system with parallel GFM converters are coupled with each other
and the transient response characteristics are more complex. In order to accurately analyze the transient response of the islanded system with parallel GFM converters
this paper establishes a three-order transient synchronization model of frequency and power angle difference of two GFM converters based on the power angle coupling equation of motion
and analyzes the characteristics of the influence of the power output difference and droop coefficients of two GFM converters on the transient stability. In order to reveal the coupling mechanism of power output and droop coefficient on transient stability
the equivalent synchronous power of parallel GFM converters is analyzed. An adaptive droop coefficient optimization strategy is also proposed based on the power output of GFM converters
which can adaptively increase the equivalent synchronous power of the parallel system and thus improve the transient stability of the system. Finally
the real-time simulation is used to verify the correctness of the three-order transient model and the effectiveness of the proposed control strategy.
