Hierarchical hybrid control for improving comprehensive performance in smart power system

Evaluation of gain scheduled predictive control in a nonlinear MIMO model of a hydropower station

“…Bonnet and Wozniak [10] developed an adaptive speed controller for a hydro-generator based on recursive least squares identification to identify an open-loop transfer function for the plant, followed by root locus design of controllers that provided uniform closed loop response over a wide range of operating conditions. Dou and Liu [11] have described how a hierarchical hybrid control can improve a power system. Although the majority of these early studies were restricted to a single on-line Unit, there have been reported controllers for multi-machine power systems.…”

Event‐triggered hybrid control based on multi‐agent system for microgrids

“…’ Corresponding to the complex hybrid behaviours of the MG, the switching control for operating mode not only can be driven by continuous dynamic behaviours but also can be triggered by discrete‐event behaviours, even more important, the different kinds of switching controls should tightly coordinate and timely interact with each other according to the hybrid characteristic. In this case, the switching control is called as event‐triggered hybrid control [20–22].…”
