ARCHE – Self-Optimizing Controls for Distributed Energy Systems
ARCHE aims to considerably simplify the use of self-optimizing control architectures for distributed energy systems in buildings. A central challenge is ensuring continuous supply security across generators, storage, and consumers using different energy carriers and conversion processes.
Holistic system and energy management coordinates variability, efficiencies, time constants, operating conditions, restrictions, and reliability and safety requirements. The aim is adaptable, self-optimizing controls for reliable and safe operation of decentralized energy systems.
The project centers on a uniform approach to designing and commissioning these controls across different applications in building operation. In particular, this is intended to reduce the market barrier created by the imbalance between design costs and design benefits.
EA Systems’ Contribution
EA Systems Dresden modeled the energy supply plants of demonstrator buildings BLA018 and BRExxx in Berlin, including the installed controls, in Modelica. The controls were then optimized and the impact of the changes documented. Three additional demonstrator plants were simulated and optimized with GreenCity for SimulationX.
Results to Date
- Preparation by ESI ITI of the control described in Modelica for integration into the real plant
- Optimization calculations by EA Systems and Fraunhofer EAS using the plant model developed by EA Systems
- Monitoring analyses, including automatically generated energy efficiency reports, by Geo-En
- Development of elements for representing plant equipment and controls
- Development of interfaces for coupling the plant model created in SimulationX with the real plant’s PLC to assess and optimize the energy impact of control code changes
