基于柔性背靠背变流器(BTBC)互联的微网群可实现不同微网间的功率解耦控制,与基于阻抗互联的微网群结构相比微网间功率交互的灵活性更高。然而,针对扰动下的BTBC互联功率控制策略及其对系统稳定性的影响尚不明确。文中建立了基于BTBC互联的微网群全阶小扰动模型,通过参与因子分析得到低频段与稳定性相关的环节,并得到与功率交互相关的主导模态,并分析了互联功率控制对系统稳定性的影响。在此基础上,提出了一种减小扰动对微网局部稳定性影响的柔性互联微网群的有功功率交换控制策略,利用根轨迹分析了该策略下系统的小信号稳定性,并结合仿真平台验证了策略的有效性。
The microgrid clusters based on flexible back-to-back converter (BTBC) interconnection can realize the power decoupling control between different microgrids. The power interaction between microgrids is more flexible than that based on impedance interconnection. However
the power control strategy for BTBC interconnection under disturbance and its influence on system stability are still unclear. This paper establishes a full-order small disturbance model of interconnected microgrids based on BTBC. The links related to stability in the low frequency band are obtained through participation factor analysis. And the dominant modes related to power interaction are obtained. The influence of interconnected power control on system stability is analyzed. On this basis
an active power exchange control strategy of flexible interconnected microgrids is proposed to reduce the impact of disturbance on the local stability of microgrids. The small-signal stability of the system with this strategy is analyzed by using the root locus. And the effectiveness of the strategy is verified by simulation platform.
