  4. 17. Combined heat and power plant flexibility - Technical and economic potential and system interaction

    Author : Johanna Beiron; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Combined heat and power; Flexibility; Process optimization modeling; Electricity price volatility; Waste to energy; Combined cycle; District heating; Dynamic modeling;

    Abstract : The share of variable renewable energy sources in electricity generation systems is expected to increase, leading to increased variability in the load that must be provided by conventional power plants or other flexibility measures. Thus, thermal power plants need to consider implementation of technical measures that enhance flexibility; to maintain profitability of operation with increased electricity price fluctuation, and to support electricity system stability.

  5. 18. Three-dimensional electron diffraction for studying order, disorder and flexibility in metal-organic frameworks

    Author : Laura Samperisi; Xiaodong Zou; Sebastian Henke; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; continuous rotation electron diffraction; metal-organic frameworks; flexibility; rotational dynamics; atomic displacement parameters; anisotropic refinement; oorganisk kemi; Inorganic Chemistry;

    Abstract : Metal-organic frameworks (MOFs) represent a class of 3D crystalline porous materials composed of organic linkers and metal nodes. Over the years, tens of thousands of MOF architectures have been developed, addressing various applications such as gas storage and separation, catalysis, chemical sensing, ion exchange and drug delivery.

  6. 19. Analysing the transient operation of the boiler and the TES tank for improving the flexibility in biomass CHP

    Author : Milan Zlatkovikj; Hailong Li; Lei Feng; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; flexibility; combined heat and power CHP ; boiler; thermal energy storage TES ; feed-forward model predictive control FF MPC ; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : 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. READ MORE

  7. 20. Wheelset Structural Flexibility and Track Flexibility in Vehicle-Track Dynamic Interaction

    Author : Nizar Chaar; Stefano Bruni; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Vehicle-track dynamic interaction; wheelset structural flexibility; Structural and vibration physics; Struktur- och vibrationsfysik;

    Abstract : 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. READ MORE
