PROJECT INTERFLEX IS TESTING THE ENERGY SYSTEM OF THE FUTURE IN EINDHOVEN
In the coming years, the pressure on the Dutch electricity networks will increase. This is because of our ambitious sustainability goals for which we will be increasingly use more electricity for transport and heating our homes, factories and offices. On the other hand the generation of energy moves from central large power plants to numerous local decentralized smaller sources throughout the Netherlands (like solar panels). The energy produced by these local sources also fluctuate much more than those of traditional power plants. In order to cope with this changing situation with the present energy networks, there are in general two options:.1) investment in network reinforcement or 2) looking for alternatives to limit consumption and supply peaks. Interflex is an innovative project of the EU H2020 program in which network operator Enexis and project partners TNO and ElaadNL participate. In this project we test various alternatives in real life situation in order to reach sustainable solutions in which energy is available everywhere at an affordable price to everyone.
Demand management via local flexibility market parties
In order to reduce the daily peaks in energy demand, Interflex is currently testing a concept for a local flexibility market place where grid operator Enexis can negotiate with service providers (aggregators) who can control the consumption of energy (such as the provider of an app for the economical smart charging of electric cars). Enexis is going to refund them via the marketplace for adjusting the energy consumption of their customers. For example, these companies can ensure that their customers charge the car at night instead of during the day. In this way, Enexis can drastically reduce the load on the electricity grid at peak times and the existing network does not need to be reinforced, or the reinforcement can be delayed for many years.
Test variable network capacity mechanism for centralized battery
Interflex is currently also experimenting with a new type of connection fee which is called as variable network capacity. We will use this type of connection within the Interflex project for the connection of the centralized battery to the electricity network. At times when the electricity grid is heavily loaded, the allowed capacity of the centralized battery is lower, which makes the charging and tapping of energy slower. However, beyond the peak times, the capacity is extra high. During these periods the battery is allowed to work faster.
