21. Behavioral demand response : A technology to support the smart grids of the future
Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Residential buildings are one of the main stakeholders to electricity consumption. As there is fast-paced technological advancement in electricity conservation, the residential buildings infrastructure has become very electricity-efficient in Sweden. LÄS MER
22. The Effect of Harmonics on the Electrical Grid due to Electric Vehicle Chargers
Kandidat-uppsats, Uppsala universitet/Institutionen för elektroteknikSammanfattning : In this thesis the effect of harmonics on the electrical grid from electric car chargers, specifically the effect on distribution transformers, is analyzed. The study was performed on the electrical grid of two areas provided by the electrical company Dala Energi. LÄS MER
23. Cross-Country Faults in Resonant-Earthed Networks
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : Reliability requirements for power systems have been constantly increasing, as customers of electric power desire high power availability. In order to improve continuity of supply in medium voltage (MV) networks, utilities in many countries in Europe, North/South America and Oceania use resonant earthing and allow the operation of the network during a single phasetoearth fault for periods from several seconds up to several hours, since the earthfault current at the fault point in such systems is considerably reduced and is unlikely to damage equipment or create hazardous voltages for people or livestock.

24. Resynchronisation of Islanded Power Systems
Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)Sammanfattning : The electricity demand and need of renewably produced electricity has increased the interest in locally produced electricity, also called distributed generation. The increase of distributed generation increases the risk of islanding, a state when a part of the grid has been electrically isolated. LÄS MER
25. Svenska körvanors påverkan på elnätet vid en elektrifiering av Sveriges fordonsflotta
Kandidat-uppsats, Linköpings universitet/Institutionen för systemteknikSammanfattning : Detta examensarbete har till uppgift att ta reda på hur det svenska elnätet påverkas av svenska körvanor vid en komplett omställning till eldrivna fordon. Genom att använda ett tidigare skapat simuleringsprogram byggt för att simulera elektriska parametrar i ett svenskt bostadsområde, är uppgiften i detta examensarbete att ta reda på ifall det nuvarande elnätet är robust nog att förse en fullt utvecklad el-baserad fordonsflotta med tillräcklig elektricitet.
