摘　　要：微电网是由分布式电源(DG)、负荷、储能和控制装置等构成的可控系统,能够充分高效地利用分布式能源资源。提出了一种基于分布式滑模控制的微电网二级电压滑模控制方法,基于图论和多智能体系统原理设计了分布式滑模控制器,该滑模控制器通过通信网络获取与其相邻分布式电源的电压信息,并利用Pade近似方法对通信网络中所产生的时间延迟进行补偿。在MATLAB/Simulink平台中对该控制方法进行仿真,验证了所提出二级电压控制策略的有效性。Microgrid is a controllable system composed of distributed generation(DG),load,energy storage and control devices,which can adequately and efficiently utilize distributed energy resources.In this paper,a secondary voltage sliding mode control method for microgrid based on distributed sliding mode control is proposed.A distributed sliding mode controller is designed under graph theory and multi-agent system principle,the sliding mode controller obtains voltage information of its adjacent distributed power supply through communication network and compensates the time delay generated in the communication network by using Pade approximation method.The control method is verified by simulation in MATLAB/Simulink platform,and the effectiveness of the proposed two-stage voltage control strategy is verified.
