21. The impact of an Electrification of Road Transportation on the Electricity system in Scandinavia
Sammanfattning : The transport sector needs to reduce CO2 emissions by replacing fossil fuels with low-carbon options. An electrification of the road transport sector through electric vehicles (EVs) with static charging; electric road systems (ERS); and using electricity to produce a fuel, are all suggested as possible options.

22. Operation, Monitoring, and Protection of Future Power Systems: Advanced Congestion Forecast and Dynamic State Estimation Applications
Sammanfattning : The electrical power systems are undergoing drastic changes such as increasing levels of renewable energy sources, energy storage, electrification of energy-efficient loads such as heat pumps and electric vehicles, demand-side resources, etc., in the last decade, and more changes will be followed in the near future.

23. Uncertainty and correlation modeling for load flow analysis of future electricity distribution systems : Probabilistic modeling of low voltage networks with residential photovoltaic generation and electric vehicle charging
Sammanfattning : The penetration of photovoltaic (PV) and electric vehicles (EVs) continues to grow and is predicted to claim a vital share of the future energy mix. It poses new challenges in the built environment, as both PV systems and EVs are widely dispersed in the electricity distribution system. LÄS MER
24. On reliability and maintenance modelling of ageing equipment in electric power systems
Sammanfattning : Maintenance optimisation is essential to achieve cost-efficiency, availability and reliability of supply in electric power systems. The process of maintenance optimisation requires information about the costs of preventive and corrective maintenance, as well as the costs of failures borne by both electricity suppliers and customers.

25. Uncertainty modeling for load flow and hosting capacity analysis of urban electricity distribution systems
Sammanfattning : Urban demographics are changing, with more than half of the global population currently residing in urban areas. Traditionally, cities are often seen as passive energy consumers relying on external centralized systems. Motivated by the need to mitigate climate change, a shift is underway as cities actively shape energy systems. LÄS MER
