Integrated energy infrastructures

There is a large potential for increasing the share of renewable energy in the system by enabling a more efficient coupling of the different parts of the energy system. A tighter coupling is also a way of improving the capability of one sector to improve the operation of another. For example can flexibility in the heating system be used as a source of flexibility in the electricity system by controlling heat pumps based on consumer needs.

Improved flexibility in the gas infrastructure includes smart compressors and gas storage in high pressure containers as well as piping, underground wells and caverns. Improved flexibility within the heating domain includes diversity in the district heating system combining high and low temperature district heating, heat pumps, and district cooling.

Examples on improved flexibility within the power systems are smart charging and V2G of electric vehicles, electrification of transportation, battery electric energy storage (BESS), server farms, and aggregated demand response from individual consumers.

In particular the fuel shift through energy conversion between the energy infrastructures is critical to a seamless integration of gas, heat, and power. The energy conversion technology includes fuel cells, electrolysers, heat pumps, ventilation and exploitation of the heat inertia provided by buildings, and other heat & cold demanding units (hot water, refrigerators, and cooling houses/containers).

The research focuses on developing control methods that can coordinate the behaviour of the different units that can provide flexibility to ensure a stable and economical operation of the combined system.

System simulation requires increased knowledge (data collection) and modelling of user behaviour, theory and modelling of building dynamics, flow & storage dynamics in piping systems, grid integration of pumps, electrolysers & fuel cells, operation of BESS, impact of weather data, co-simulation, and integrated simulation of multiple energy systems.
