1. Local Voltage Control in Converter Based PV Generation
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : As the world is trying to rid itself of its dependence on fossil fuels, the need for renewable energy is rapidly increasing. In the power distribution network (DN), this takes the form of distributed generation (DG) from renewable sources, such as photovoltaic (PV) power production. LÄS MER
2. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. LÄS MER
3. Graphene Based Aqueous Ammonium Dual-Ion Batteries
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/StrukturkemiSammanfattning : The global transition to renewable energy sources is placing high demands on the development of effective energy storage methods, the most prevalent being batteries. Dual-ion batteries are a new battery technology that takes advantage of the simultaneous intercalation of both cations and anions. LÄS MER
4. Energikartläggning av mobilt batterilager i kombination med en högeffektsladdare och påverkan på det lokala elnätet
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/ElektricitetsläraSammanfattning : To achieve the established environmental goals, a significant transformation is requiredin the Swedish transport sector. This includes a shift away from fossil fuels and a greateremphasis on electrifying a larger portion of the vehicle fleet. LÄS MER
5. Application of electrodes with redox mechanisms for the desalination of water
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Capacitive deionization is a promising technology for purification and desalination of brackish water with great advantages over current technologies due to its low operating cost and high-water recovery ratio. Most of the system studied relies on the adsorption/desorption capacity of activated carbon electrodes due to its high surface area. LÄS MER
