Optimization of design and control of district level thermal energy systems

Purpose and goal

The aim is to develop models for complex district-level thermal systems and to use them to find optimal control strategies. The focus lies on optimization of design as well as control of systems that are equipped with a combination of storage (seasonal and/or short term) heat pumps, free sources, CHP units and conventional boilers. DEBORAH relies on advanced simulation at building, district and plant levels, on cloud high performance computation resources, and on recent advances in model predictive control.

Expected results and effects

- Holistic simulators for complex district thermal systems - Optimization tools for design and operation Using the developed tools, design as well as operation will be optimized. This will lead to performance gains, which in turn will reduce the environmental impact of buildings.

Planned approach and implementation

The planned models will be an extension to EQUAs existing simulation environment for buildings and energy production plants. EQUA will develop the new models; CSEM and Neurobat in Switzerland will develop new model predictive controls. Testing is done at the existing district facility of BDAB in Krokslätt, Gothenburg.
