Speech Title:

Embedded and Interacting Network Systems

Abstract

Management of networked systems requires integrated control, communications, and computing. Many network systems form a hierarchical or embedded structure with interactions. In this talk, we report some recent progress on networked systems and their interactions. Using renewable energy systems as an example, we demonstrate how a microgrid, a team of autonomous/semi-autonomous dual-powered trolley buses, and vehicles' internal battery networks, all of which are networked systems themselves, are connected and intertwined.
These interacting networked systems introduce very different network control issues.
(1) Fair distribution to distributed generators, power loss on transmission lines, voltage management on buses are main issues in a DC microgrids. These problems can be formulated as distributed and constrained optimization problems.
(2) Microgrid-supported trolleybus systems need to coordinate on-board battery systems and reduce load fluctuations on the grid. Vehicle dynamics, battery dynamics, and lack of vehicle-to-vehicle communications lead to decentralized dynamic optimal control problems.
(3) On-board battery networks must operate in a balanced manner to maximize their ability in supporting trolleybuses. Battery networks are inherently unobservable and uncontrollable. Switching actions need to be added to achieve stability, performance, optimality, robustness. Consequently, we encounter hybrid network control problems.
In this talk, we will summarize briefly some effort in these directions.
