Distributed Cooperative Control for DC Microgrids with Communication Time Delays Using Networked Predictive PI Scheme

This paper is concerned with the communication time delay problem in the cyber-physical DC microgrid. A networked predictive PI control scheme is proposed to realize simultaneous voltage recovery and power sharing in the presence of time delays. The proposed method actively compensates for communication delays in a distributed manner. Owing to the proactive prediction, the microgrid can achieve a good performance with delays in the cyber layer. The effectiveness of the proposed scheme is validated via detailed simulations.
