摘　　要：在孤岛交流微电网电压和频率的协调控制中,存在着依赖周期通信、通信负担大等问题.为此,提出了一种基于动态事件触发的分布式协调控制策略,在微电网中运用多智能体系统理论,将频率和电压作为追踪同步目标.通过评估事件触发条件,从根本上摆脱了分布式电源DGs的连续通信和Zeno行为.并引入与系统偏差和反馈有关的动态变量,合理调整触发阈值和反馈增益.此方案提高了通信效率,降低了控制更新频率,保持了良好的控制性能.并且在Matlab/Simulink环境中验证了所设计控制策略的正确性和有效性.In the coordinated control of voltage and frequency in isolated AC microgrids,challenges such as reliance on periodic communication and high communication burden exist.To address these issues,a distributed coordinated control strategy based on dynamic event triggering is proposed.The strategy employs the theory of multi-agent systems within the microgrid,treating frequency and voltage as tracking synchronization targets.By evaluating event triggering conditions,the strategy fundamentally eliminates continuous communication and Zeno behavior in distributed generators(DGs).Additionally,dynamic variables related to system deviation and feedback are introduced to judiciously adjust triggering thresholds and feedback gains.This approach enhances communication efficiency,reduces control update frequency,and maintains good control performance.The correctness and effectiveness of the proposed control strategy are validated in the Matlab/Simulink environment.
