1. 1. Analysis of a hybrid PV-CSP plant integration in the electricity market

   Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Juan Vicente Maz Zapater; [2023]
   Nyckelord :Concentrated Solar Power CSP ; Photovoltaic PV ; Molten Salts; supercritical CO2; Thermal Energy Storage; Battery Energy Storage System; MoSES; Energy Dispatcher;

   Sammanfattning : One of the key challenges the world will need to face during the 21st century is global warming and the consequent climate change. Its presence is indisputable, and decarbonizing the gird emerges as one of the required pathways to achieve global sustainable objectives. LÄS MER

3. 2. Determination of Proton Beam Waist Positions Using Beam Position Monitors

   Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/European Spallation Source ESS AB; Lunds universitet/Synkrotronljusfysik

   Författare :Gustav Gird Fahlström; [2022]
   Nyckelord :ESS; European Spallation Source; Proton beam; waist; BPM; Method; transverse; beam dynamics; beam physics; Lattice Error; Matrix formalism; Python; trajectory simulation; physics; Physics and Astronomy;

   Sammanfattning : In this work, we examine a novel method for the determination of proton beam waist locations using beam position monitors. Based on the lattice of the final transport line section of the European Spallation Source linac, a simplified version of the beam line composed of quadrupole magnets and correctors is constructed in Python using a matrix formalism.

4. 3. Simulation of a Battery Energy Storage System for Fast Frequency Reserve Support.

   Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

   Författare :Pathirage Dona Upekha Nimanthi Pathirage; [2022]
   Nyckelord :Energy Storage; Renewable Energy; Battery; Fast Frequency Reserve; Lithium-ion;

   Sammanfattning : Electricity providers has a growing interest in moving towards Renewable Energy Sources (RES) for power generation due to their attractive features. This has caused phasing out of coal, oil and nuclear power plants which use large synchronous generators for power production. LÄS MER

5. 4. Small Signal Stability of Power Systems With Increased Converter Based Power Production

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

   Författare :Gustav Kjellson; Josefin Gustafsson; [2022]
   Nyckelord :Small signal stability; Power system stabilizer; Renewable energy; Grid following converters; Grid forming converters;

   Sammanfattning : The aim of this project is to analyze how increasing the share of converter-based power production in a power system affects the small signal stability. The project also aims to stabilize systems using Power System Stabilizers (PSSs), and examine the effect of two different types of power electronic converters: grid following (GFL) and grid forming (GFM).

7. 5. Marknadsdeltagande mikroelnät : En tekno-ekonomisk studie av lönsamheten för ett mikroelnät som deltar på elmarknader för flexibilitets- och stödtjänster genom förbrukningsflexibilitet och batterilager

   Magister-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Anton Thorstensson; [2021]
   Nyckelord :;

   Sammanfattning : This thesis examines the changes in profitability of an investment in a battery energy storage system (BESS) for a property when it, in addition to contributing to local benefits such as peak shaving, also supports the grid through the delivery of primary frequency control services. The Mall of Scandinavia shopping center in Solna acts as study object and is dealt with as a micro grid consisting of the property's loads, PV facility, the BESS and 300 controllable chargers for electric vehicles.
