Distributed Predefined-Time Dual-Mode Energy Management for a Microgrid Over Event-Triggered Communication

This article investigates the coordination dual-mode energy management problem (EMP) for a microgrid. First, the islanded and grid-connected modes are modeled into a unified form, which enhances the adaptability and flexibility of the microgrid. Second, a novel distributed algorithm is designed to solve the EMP. By the algorithm, each participant adaptively responds to the change of mode switching and obtains its optimal operation in a distributed way. Besides, compared with the existing distributed energy management algorithms, the convergence time can be predefined exactly by the users, which is independent of any designed parameters and the initial states. Furthermore, the communication strategy is event-triggered, which reduces communication resource consumptions greatly. Finally, simulation results are presented to demonstrate the effectiveness of the designed model and algorithm.
