The transition to decentralised energy production, efficient technologies and the electrification of heating and transportation all contribute to the question of whether the current “lock-in” of AC technology for building technologies is still justified. To explore the potential of DC low-voltage technologies, a 750V/100 kW bipolar DC nanogrid was set up at EnergyVille’s Home Lab. This lab provides a configurable, flexible test environment for DC components and systems, and is unique in Flanders. Our research mainly focuses on implementation, stability and safety aspects of DC nanogrids for different applications in buildings and on an industrial scale, and is closely aligned with the power electronics research line.
