PhD defence by Marko Angjelichinoski

 “Advanced Bus Signaling Methods For DC Microgrids”

This thesis introduces a novel bus signaling technique for communication over the powerlines among decentralized control agents in direct current MicroGrids. The solution is termed power talk and it proposes each controller to modulate the control messages into the parameters of the local droop control loop. This will cause subtle deviations of the steady state bus voltages from which remote controllers across the MicroGrid can demodulate the desired information. Unlike traditional networked control approaches, power talk offers several inherent advantages compared to external communication systems in terms of the service requirements, cost and security.

The general communication problem is a non-standard one and imposes several unique challenges, not encountered frequently in common communication setups. In light of this, the contributions of the thesis are divided into two categories. First, the thesis presents a set of concepts, techniques and practical solutions for designing reliable power talk interfaces and communication protocols in challenging circumstances. Afterward, the focus shifts on applying power talk for common control applications such as monitoring, optimization and cyber-secure control.
