Distributed Hybrid-Triggered Observer-Based Secondary Control of Multi-Bus DC Microgrids Over Directed Networks

The secondary control (SC) of DC Microgrids (MGs) exhibits fast control dynamics as a consequence of low system inertia, leading to substantial communication, networked sensor sampling, and computational load. The existing pure event-triggered (ETed) or self-triggered (STed) SC approaches for DC MGs struggle to optimize communication, sampling, and computation efficiency concurrently. To address this issue, this study introduces a novel distributed hybrid-triggered (HTed) dynamic-consensus-observer-based SC tailored for average voltage restoration and load current sharing in general multi-bus DC MGs over directed networks. Firstly, the dynamic model of SC over directed networks is established. Subsequently, a…
