An effect of climate change is fewer cold days and less natural snow at lower elevations. This has spurred the interest in temperature independent snow (TIS) production, i.e., refrigeration technologies that can produce snow at ambient temperatures above zero. Commercially available TIS systems require...

...electricity and thermal energy due to energyintensive processes such as steam production, cleaning, sanitising, refrigeration and drying. Furthermore, there is often a considerable thermal demand for heating the building and for air‐conditioning purposes. Dairy plants require both heating and cooling at...

In order to perform reliability assessment studies involving the influence of WAMS and extreme contingencies, it is essential to have a good representation of the dynamic behaviour of the system. This paper describes a proposed improvement of the benchmark model IEEE Reliability Test System 1996...

...on the western coast of Norway. The following alternatives for energy supply are modelled and analysed: i) a district heating system with three different heat centrals, ii) a natural gas distribution system and iii) a low temperature distribution system. The case study is performed with the optimization...

...modelling and experimental effort to develop physicsbased combined thermodynamic and transient flow models for CO₂-transport pipelines. Such models need to handle both multiple components and two-phase flow, which can occur both during normal operation and transient situations, such as first fill and depressurization...

The focus of the project "Methods of aggregation and disaggregation" are improved mathematical methods and computer tools for aggregation and disaggregation of hydro power systems in optimization models. These techniques are necessary for calculating the optimal utilisation of hydropower production...

...measures. Various advanced optimization methods for active grid measures are presented in the research literature, but they are rarely used in practice and are not always well suited to informing decision processes in distribution grid planning. To bridge this gap, this paper presents a framework for active...
