Decentralized Communication-free Secondary Voltage Restoration and Current Sharing Control for Islanded DC Microgrids
This paper presents a decentralized secondary control scheme to solve the voltage restoration and current sharing problem in islanded DC microgrid (MG) systems. The existing solutions to this problem are either centralized control or distributed control based approaches. For these methods, communication and information exchange is inevitable. In order to improve the system robustness and reduce the system implementation cost, a decentralized communication-free leaky integral control is proposed in this paper, which is able to realize the same control goals without any communication. The stability of overall system together with proposed decentralized controller is analysed. A test DC MG system is built in Matlab Simulink to validate the effectiveness of proposed control method.
