Abstract

Islanded microgrids are autonomous electric systems composed of distributed generation units (DGUs) and loads interconnected through electric lines and exchanging information over a communication network.  On the economical side, microgrids offer a paradigm for agile power systems where consumers and owners of small generation units can join and leave over time. In this vision, a central role is played by the concept of flexibility: ideally, the microgrid technology should allow DGUs and loads to plug in and out with minimal supervision effort, while guaranteeing safe and reliable operation at all times.

In this talk I will focus on DC microgrids and present decentralised primary controllers for voltage stability as well as consensus-based secondary regulators for current sharing. Moreover, I will discuss distributed algorithms for detecting cyber attacks targeting the secondary layer. Most importantly, the design algorithms will be scalable, meaning that, when a component is plugged in or out, stability and safety can be preserved by updating just a limited number of local controllers and detectors. Simulations and lab experiments will be presented for illustrating the applicability of the proposed methods.
