1. 21. Robust TCO’s for CIGS solar cells based on indium tin oxide

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Julia Nilsson; [2022]
   Keywords : photovoltaics; solar cells; thin film photovoltaics; PV; TCO; transparent conductive oxide; indium tin oxide; ITO; CIGS; solar power; sputtering; RF sputtering; radio frequency sputtering;

   Abstract : The increasing energy demand, combined with the use of harmful non-renewable energy sources calls for the search of alternative methods to cover our energy need.Renewable energy can be harvested in different ways, through the movement of wind and water, biomass, or directly from the rays of the sun, as in the case of photovoltaic (PV) devices.

3. 22. Damping of sub-synchronous control interactions with a STATCOM : Wind farms & series compensated power lines

   University essay from Uppsala universitet/Institutionen för elektroteknik

   Author : Leonardo Alvarez Urrutia; [2022]
   Keywords : Sub-Synchronous Control Interactions; Power Systems; STATCOM; Network Stability; Doubly-Fed Induction Generator; Impedance-Based Stability Analysis;

   Abstract : The power converter is one of the key components in power system applications such as high voltage direct current (HVDC) systems and the grid connection of intermittent sources such as wind and solar power. However, the increased penetration of converter-based generation introduces challenges, such as sub-synchronous interaction between the converter control system and the grid. READ MORE

4. 23. Reactive power compensation of the electricity grid with large-scale offshore wind farms in Sweden : Technical capabilities, grid codes and economic incentives

   University essay from Uppsala universitet/Elektricitetslära

   Author : Agnes Bråve; Sara Särnblad; [2022]
   Keywords : Wind power; offshore wind farm; reactive power; reactive power market; grid code; RfG; voltage stability; Vindkraftspark; havsbaserad vindkraft; reaktiv effekt; reaktiv effektmarknad; nätkod; spänningsstabilitet;

   Abstract : Year 2040 the goal is to have a 100 % renewable Swedish energy system. Svenska kraftnät (Svk) predicts fully decommissioned nuclear power plants and an increased amount of connected wind power plants, especially offshore, year 2045. READ MORE

5. 24. Frequency Stability of Power Electronic Based Power System with 100% Renewable Energy.

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Abdullah Albalali; [2022]
   Keywords : energy storage; frequency control; synchronous generators; distributed power generation; virtual synchronous machine VSM ; PSCAD.; energilagringssystem; frekvenskontroll; synkrona generatorer; distribuerad kraftproduktion; virtuell synkron maskin; PSCAD.;

   Abstract : The modern power system is aiming to progress away from conventional synchronous machine  based power generation towards converter dominated system that leads to extensively high penetration of renewable energy such as wind and PV. This transition of modern power system toward converter based renewable energy comes with new challenges as the conventional synchronous generation is being replaced by converter based power system (CBPS).

6. 25. Supporting Frequency Stability With Batteries in Low Inertia Power Systems

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Sophie-Linn Karlsson; Tim Asking; [2022]
   Keywords : Battery Power Support; Fast Frequency Reserves; Frequency Containment Reserves; Inertia; Renewable Energy Sources;

   Abstract : As the share of power electronics-based renewable energy sources increases in power systems, the system inertia provided by conventional generation is reduced. Inertia is an important factor in the grid's frequency stability, and with its reduction comes challenges to ensure the reliability of the grid. READ MORE
