21. Analysing the transient operation of the boiler and the TES tank for improving the flexibility in biomass CHP
Sammanfattning : The uncertainty in the energy systems due to the continuously growing share of variable renewable energy sources (VRES) increases the requirements for flexibility. From the multiple mechanisms to improve flexibility, biomass-fired combined heat and power plants (CHPs) have gained attention due to their sustainability and high efficiency. LÄS MER
22. Wheelset Structural Flexibility and Track Flexibility in Vehicle-Track Dynamic Interaction
Sammanfattning : This thesis investigates the influence of wheelset structural flexibility and track flexibility on the vehicle-track dynamic interaction, mainly in terms of wheel-rail forces up to 200 Hz, using simulations and measurements. The previous knowledge in this field is first reviewed and summarized, then two case studies are selected for investigation. LÄS MER
23. Short- and long-term variability in future electricity systems – Ensuring the flexibility to manage the grid frequency and inter-annual variations
Sammanfattning : To achieve climate mitigation targets, the net climate impact from electricity generation must be drastically reduced in the near future, and eventually eliminated. The level of generation must also be increased to accommodate the increasing demand as the transport and industry sectors undergo electrification. LÄS MER
24. Combined heat and power plants in decarbonized energy systems: Techno-economics of carbon capture and flexibility services at the plant, city and regional levels
Sammanfattning : Our present energy system is the main driver of climate change. Variable renewable electricity generation and carbon dioxide removal (CDR) are key technologies in the transformation to a sustainable energy system, but their broad implementation implies challenges related to energy system flexibility and energy requirements of CDR technologies.

25. Towards sustainable energy consumption : Electricity demand flexibility and household fuel choice
Sammanfattning : Paper [I] investigates household heterogeneity in valuing electricity contract attributes that include various load controls and information sharing to induce demand flexibility. Using a stated preference choice experiment conducted with Swedish households, this paper shows that, although a large proportion of households ask for substantial compensation, some households are willing to share their electricity consumption information and require relatively lower compensation to allow load controls.
