2. 1. Optimization modeling of frequency reserves and inertia in the transition to a climate-neutral electricity system

   Author : Jonathan Ullmark; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; generation expansion planning; frequency reserves; inertia; Energy system modeling; synthetic inertia; frequency control;

   Abstract : The ongoing transition towards electricity production systems that are dominated by wind and solar power challenge both the traditional strategy for meeting a varying electricity demand and the traditional way of controlling the AC frequency of the electricity grid. This work investigates how frequency reserves (FR) and inertia, as well as inter-hourly variation management interact in the transition to a climate-neutral electricity system. READ MORE

4. 2. Decentralization in energy systems - Low-carbon technologies and sector coupling on the household, community and city scales

   Author : Verena Heinisch; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prosumers; Energy system flexibility; Decentralization; Energy community; Smart city; Sector coupling; Electric vehicles; Energy systems modeling;

   Abstract : The number of installations of distributed energy technologies, such as solar photovoltaic (PV) and battery systems, has increased dramatically in recent decades. The required transition towards a decarbonized energy system entails electrification of the different sectors. READ MORE

5. 3. Energy Usage in Supermarkets - Modelling and Field Measurements

   Author : Jaime Arias; Per Lundqvist; Denis Clodic; KTH; []
   Keywords : Supermarket; Energy Performance; System Analysis; Modelling; Simulation; Field Measurements; Refrigeration Systems; Indirect Systems; Heat Recovery; Floating Condensing; TEWI; LCC.; NATURAL SCIENCES; NATURVETENSKAP;

   Abstract : This thesis investigates a special type of energy system, namely energy use in supermarkets through modelling, simulations and field studies. A user-friendly computer program, CyberMart, which calculates the total energy performance of a supermarket, is presented. READ MORE

6. 4. Predicting Electrochromic Smart Window Performance

   Author : Johnny Degerman Engfeldt; Göran Lindbergh; Carina Lagergren; Kerstin Forsberg; James Gardner; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrochromic; Electrooptics; Smart windows; Prediction model; Large Area Device model;

   Abstract : The building sector is one of the largest consumers of energy, where the cooling of buildings accounts for a large portion of the total energy consumption. Electrochromic (EC) smart windows have a great potential for increasing indoor comfort and saving large amounts of energy for buildings. READ MORE
