Smart Solar Geothermal Energy Grid Ruhr
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.
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.
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.
