   Sammanfattning : The electricity grids have become a key player in the society. An increased usage of electricity is both a result from the more electrified society, but also as a main solver in reaching the climate goals by reducing emissions. LÄS MER

4. 23. Short-horizon Prediction of Indoor Temperature using Low-Order Thermal Networks : A case study of thermal models for heat-system control applications

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jonas Cederberg; [2023]
   Nyckelord :Lumped Parameter Thermal Network; Resistance-Capacitance model; Parameter estimation; Modelling of Dynamical Systems; Thermal modelling; Temperature Prediction; Termiskt nätverk med klumpade parametrar; Mostånds-kapacitans modell; Parameterestimering; Modellering av dynamiska system; Termisk modellering; Temperaturprediktion.;

   Sammanfattning : Optimizing and controlling the heating systems in buildings is one way to decrease their load on the power grid, as well as introduce load flexibility to be used in Demand Response (DR) applications. A requirement in occupied buildings is that the thermal comfort of the residents is guaranteed, making the optimization of heating systems a constrained problem with respect to indoor temperature.

5. 24. Service life study of environmentally friendly lubricants.

   Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Författare :Marybeth Chetachukwu Ugoh; [2023]
   Nyckelord :Base oil; Ageing; Glycerol; PPG; PEG; Squalene; Rapeseed oil; Ester; Paraffin; Oxidation; FTIR;

   Sammanfattning : Environmentally friendly lubricants are in demand in response to the rising concerns and restrictive legislation that surround the use of mineral oil lubricants. One area of importance is understanding the service life of the environmentally friendly base oils of these non-toxic, biodegradable and renewable alternatives. LÄS MER

7. 25. Analysis of 2022 Demand Response Events in California: Baseline Modelling using the SARIMAX-GARCH Model

   D-uppsats, Handelshögskolan i Stockholm/Institutionen för nationalekonomi

   Författare :Norbert Oros; [2023]
   Nyckelord :Demand response; Energy modelling; Electricity demand;

   Sammanfattning : This study investigates the use of a combination of SARIMAX and GARCH models to create baselines for electricity demand, generation, and interchange in order to analyze deviations during demand response events. Demand response plays and will continue to play a crucial role in the management of the electric grid during periods of extreme imbalances. LÄS MER
