Description
In this talk we focus on passivity properties of direct current (DC) microgrids. We propose a distributed control scheme, achieving current sharing and average voltage regulation. The considered DC microgrid is composed of several distributed generation units (DGUs) interconnected through resistive inductive power lines. Each DGU includes a generic energy source that supplies a local current load through a DC-DC buck converter. The load models represent the large class of ZIP loads. The proposed distributed control schemes achieves current sharing and average voltage regulation, independent of the initial condition of the controlled microgrid and the values of the loads. Moreover, the proposed solution is independent of the microgrid parameters and the topology of the used communication network, facilitating plug-and-play capabilities. Global convergence to a desired steady state is proven and simulations indicate a good performance. Additionally, we consider other types of DC-DC converters, and study novel passivity-based control methods called input shaping and output shaping for these converters. Then, these closed-loop systems are embedded in a DC grid setting and the overall behaviour is analysed.| Periode | 2022 |
