Smart Solar Geothermal Energy Grid Ruhr

DigitalisationEnergy

Successful thermal energy transition requires the further development of renewable energy systems and moreover, the integration of the systems into the existing infrastructures. The aim is the flexible, decentralised feed of solar and geother­mal heat into thermal energy networks utilising former coal mine workings.

 

Starting point

Successful thermal energy transition requires the further development of renewable energy systems, the integration of the systems into the (existing) decentralised and centralised infrastructures, as well as making available user specific information and control op­tions. This demands a stronger coupling across systems and en­ergy carriers of energy systems, like optimally matched system components, whose interaction via control and regulating sys­tems and centralised software platforms are enhanced for effi­cient data processing. While the virtualisation of intelligent power networks is by now in the standardisation phase, many thermal energy sources are not equipped with relevant components.

Our Solution

The aim is the flexible, decentralised feed of solar and geother­mal heat into thermal energy networks utilising existing supply and network structures; Seasonal excess heat, though, is to be stored in former coal mine workings. For the decentralised part, bidirectional thermal consumer/producer systems are planned, for example buildings with district heating connection and solar thermal energy. In this heat grid a distributed system architec­ture is required where both consumers and producers can be connected by intelligent IoT middleware and cost effective con­trol devices via hardware solutions and a cloud based software platform.

The solution concept integrates various hardware and software compo­nents. Smart Device Controllers (SDC) represent the decentral­ised low cost hardware modules that tie in the sensors and ac­tuators in mine workings and small producers. They capture energy data and send switching commands to local control sys­tems. Data is initially aggregated and pre-filtered locally before being transmitted to the cloud platform. Several SDC will be lo­cally clustered to improve the control and stability of the whole network, especially in case of limited outages. The thus struc­tured components together form a so called Smart Grid.
