Networks

EnergyVille investigates the development, operation and use of electrical networks, starting with the user and continuing on up to the transmission system. We focus on a seamless integration of renewable energy sources, both into distribution and transmission systems and into developed areas. EnergyVille envisages the development, demonstration and implementation of intelligent control of networks and substrations, tools for designing DHC networks, low temperature networks, multi-carrier energy networks and district cooling networks.

 

Electrical networks

In a system that is dependent on intermittent, weather dependent renewable energy sources like wind and PV, a demand response system where the consumer decides when he needs electricity is not that simple anymore. Not only do we need to take into account imbalances between demand and supply, there are also peak moments, reverse energy streams and overloads. A good interaction of renewable energy with both the distribution and transmission system and the built environment is therefore an important research topic at EnergyVille.

District heating and cooling networks

The heating and cooling of our buildings accounts for more than 50% of the total EU energy demand. Today this demand is mainly filled in by burning fossil fuels, but the pressure on the energy supply and the climate compels us to focus on renewable energy and sustainable sources like waste heat. One of the areas EnergyVille is working on to unlock the potential of waste heat is district heating and cooling networks (DHC). Heating networks can match the demand and supply of heat and can function as infrastructure for all sorts of sustainable heat. The coupling of heating networks and electrical networks by means of, for instance, heat pumps or ORCs remains an important topic of research. One of the research domains in this regard is sustainable district heating and cooling networks or DHC-networks. Intelligently controlled DHC-networks are vital in the transition to carbon free solutions. Therefore, the focus lies on fourth generation networks and on the challenges posed by the third generation networks all over Europe.
