Decentralized synchronization of inverter based grid


Jean-Sébastien Brouillon

Marcello Colombino, Florian Dörfler

All around the world we are witnessing an increased penetration of renewable energy in the power grid. Traditional generators synchronize to the same frequency through the electromechanical coupling provided by the physics of the grid. Photovoltaic and wind generators are connected to the grid via power inverters that do not inherit these synchronizing properties.

Traditionally, power inverters are controlled to track the frequency of the grid and inject a predefined amount of power. This is only possible if there are enough synchronous generators that keep the grid running.

The goal of this project is to study synchronization algorithms for a grid without synchronous generators. This is an ambitious task as the inverters must synchronize without communication and they can only rely on locally available information.

The student will evaluate traditional control schemes for power inverters that are presented in the literature, compare them with more advanced schemes that are being proposed at the institute and propose control schemes that allow these algorithms to be implemented on a realistic model of the inverter.
