摘　　要：研究的主要目的是为提升多母线直流微电网的稳定性和可靠性。采用信息–能量复合调制策略、多智能体协同控制、动态事件触发通信协议等方式,通过对多母线直流微电网的结构和运行特性进行分析,建立更为有效的控制策略。实际情况表明,该控制策略能够有效提高系统的动态响应能力,减小电压波动范围,进一步增强系统的稳定性和可靠性。该控制策略还具有较好的鲁棒性和适应性,能够应对不同的系统参数变化和外部扰动。因此,该控制策略可实现对多母线直流微电网中各分布式电源的电压和电流的协同控制,在此基础上,还可提高系统的动态响应能力,减小电压波动范围。This study aims to improve the stability and reliability of multi bus DC microgrids.We adopt information energy composite modulation strategy,multi﹣agent collaborative control,dynamic event triggered communication protocol and other methods to analyze the structure and operational characteristics of multi bus DC microgrids,and establish more effective control strategies.According to the actual situation,this control strategy can effectively improve the dynamic response ability of the system,reduce the range of voltage fluctuations,and further enhance the stability and reliability of the system.And it was found that this control strategy also has good robustness and adaptability,and can cope with different system parameter changes and external disturbances.Therefore,it is concluded that this control strategy can achieve coordinated control of voltage and current of various distributed power sources in a multi bus DC microgrid.On this basis,it can also improve the dynamic response ability of the system and reduce the range of voltage fluctuations.
