REsys – Smart control strategies to improve the energy efficiency of complex hybrid energy systems

Hybrid energy systems are systems that combine different energy sources, energy distribution and storage in a compact system. The knowledge of the interdependencies and interactions between system components is the basis for the optimal design and the energy efficient operation of future and existing hybrid systems. Today empirical data from non-hybrid systems is used for the layout design of hybrid systems, with the drawback, that the system interrelations and the number of relevant influencing factors are not taken into account. Within REsys models, simulations and analyses are built on measured and statistical data. By the use of ICT-methods and experts knowledge smart control strategies are developed and subsequently tested in simulations and on a real hybrid energy system. Additionally the transferability of the results to other hybrid energy systems is evaluated.

The objectives are:

1. Improvement of the energy efficiency of future and existing complex hybrid energy systems.
2. Generation of know-how regarding the interdependencies and interactions between components in such systems.
3. Open up innovative methods for the analysis of big data, generated by a multitude of measuring sensors.
4. Development of system oriented simulation models with open system boundaries, validated by measured and statistical data.
