1. Substation Digitalization for Medium Voltage Urban Distribution Networks : A Techno-Economic Analysis
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : High and medium-voltage digital substations play an essential role in the energy transition since they are part of the equipment required to deploy smart grids. With the gradual increase of smart grids, energy systems are becoming more flexible with the growing penetration of renewable energies and distributed energy generation. LÄS MER
2. Prediktivt underhåll av transformatorstationer genom automatisk analys av störningsdata i COMTRADE-filer
M1-uppsats, KTH/Hälsoinformatik och logistikSammanfattning : Arbetet beskriver möjligheten att kunna utföra prediktivt underhåll med hjälp av information frånCOMTRADE störningsfiler. En mjukvarualgoritm som hämtar tidsförlopp för händelser som uppstårvid störningar och kan ge indikationer på ifall reläer eller strömbrytare faller utanför optimalaarbetsförhållanden har utvecklats.

3. Evaluating the Efficient Grid Utilisation Incentive : Through the design of the load flow indicator
Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Industriell ekonomi och organisationSammanfattning : The Swedish energy markets inspectorate (Ei) regulates the Swedish DSOs revenue cap, to ensure reasonable prices, efficiency, and quality of supply towards the end users. In combination with directives from the European Union and Sweden's environmental goal, Ei implemented efficient grid utilization to the DSOs revenue cap in 2016. LÄS MER
4. System impact of micro-production
Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automationSammanfattning : The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-requirements in the RfG. LÄS MER
5. Substation digitalization and fault isolation : A study of the influence of degree of digitalization to regulatory indicators in the power grid
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : With changes in the energy sector, more demand is set on the power grid as electricity consumption is seen to increase and more decentralized renewable energy production is connecting to the grid. Svenska Kraftnät, electric system transmission operator in Sweden, describes the importance a more secure operation of the power system. LÄS MER
