The DIRECTIONS project aimed to perform fundamental research examining the technical choices surrounding the ‘energy hub’ concept, and apply this fundamental research to a Belgian case study. The project addressed the identified technical challenges under three core topics; the planning of energy hub topologies, the control of devices within energy hubs and of the overall energy hub, and the protection system design for energy hubs. The fundamental research provided generic outcomes applicable to all foreseen energy hub designs for near future implementation, and this fundamental research was then applied to the Belgian case study with appropriate topologies and parameters for foreseen system configurations. With the combination of in-depth generalised academic research and research towards industrial application, the project made significant progress towards effective energy hub designs both in the Belgian context as well as across Europe.
