摘要：

In order to solve the problem of current sharing cooperative control among distributed DC microgrid groups, firstly, the distributed generation units in DC microgrid are regarded as heterogeneous multi-agent, and the physical model of DC microgrid system is established. Secondly, according to the hierarchical control design principle of power system, a hybrid secondary control strategy based on discrete-time pulse cooperative control is proposed to design DC microgrid The reference output voltage of each distributed generation unit is designed by pulse control method in the secondary controller, and the voltage tracking controller of power converter is designed by double PI voltage and current control method in the primary controller. Thirdly, based on the stability theory of hybrid system, the sufficient conditions of time and current sharing cooperative control of DC microgrid are obtained Finally, the effectiveness of the algorithm in DC microgrid is verified by Matlab / Simulink.
