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.
