SHORT-TERM MODELING OF HYBRID GEOTHERMAL SYSTEMS FOR MODEL PREDICTIVE CONTROL

File size: 2mb

Authors: Iago Cupeiro Figueroa, Damien Picard and Lieve Helsen

Highlights

• A simulation study assesses the impact of COP formulation and borefield controller model for model predictive control of a hybrid geothermal system.
• Using an accurate COP formulation presents a smoother and more efficient heat pump behaviour.
• Including a borefield controller model avoids hitting the heat pump safety freezing constraints, improving robustness.
• Despite reducing the number of iterations in the optimisation, the simulation time is increased, however still feasible.

The aim of the hybridGEOTABS project within the EU Horizon2020 programme is to perform research and developments necessary to put hybridGEOTABS closer to the market. The results show that the system can provide 10-60 % reduction in CO2 emissions at an investment price lower than 5 % (typically lower than 3 %) of the total building investment.  
The hybridGEOTABS system uses the combination of Thermally Activated Building System (TABS) powered by ground-coupled heat pump as a primary source and a suitable secondary source, with advanced automation system (Model-based Predictive Control, MPC). This combination enables us to operate the heat pump under better performance conditions and to use the building thermal mass efficiently, which in turn results in better system performance, energy and CO2 savings, while maintaining high indoor environmental quality.
The system is fully compatible with the EU policies, such as the SET Plan, EPBD and European Green Deal, and has the potential to contribute to the climatic goals set by the EU.  
In order to attract more attention and facilitate wider application of the hybridGEOTABS system in future building projects, following points need attention on the EU level:

Promotion of Integrated Approaches within Financial Instruments

  • hybridGEOTABS is one example of and integrated approach, where the building is designed and build in an integrated manner (unlike most of the state-of-the-art projects in EU)
  • Because of higher efficiency, these projects should receive better financing conditions

 

Further Research – hybridGEOTABS Buildings as Smart Grid Prosumers

  • Next step in the research should be the integration of hybridGEOTABS buildings into the smart grid concept, which is heavily promoted e.g. by SET Plan and the European Green Deal

 

Raising General Awareness of the hybridGEOTABS Concept

  • Even though the respective components of the hybridGEOTABS concept are widely known and used in building construction, the strength of the concept is in the integration of all modules and their optimal control by means of Model Predictive Control (MPC).
  • To promote the concept, the Knowledge Centre has been founded and will assist the practitioners in designing new hybridGEOTABS buildings.

POTENTIAL OF THE MPC HYBRIDGEOTABS CONCEPT FOR BUILDINGS: LIBEZNICE SCHOOL

File size: 587kb

Authors: Yauheni Kachalouski, Jiri Cigler and Lukas Ferkl

As a part of hybridGEOTABS project, Libeznice school is one of several demonstration cases that employs geothermal heat pump with Thermally Activated Building Systems (TABS) combined with Model Predictive Control (MPC) algorithms for heating and cooling. Benefits and potential of such a system is presented in this article.
