5. 4. Jämförande analys av åtgärder vid kapacitetsbrist i kraftledningar

   M1-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

   Författare :Daniel Dahlstrand; [2022]
   Nyckelord :Power systems; transmission line; capacity shortage; overload; flexibility; dynamic line rating; approximation; Elkraft; kraftledning; kapacitetsbrist; överlast; flexibilitet; dynamisk ledningskapacitet; uppskattning;

   Sammanfattning : Marknadsanalyser gjorda av Svenska kraftnät visar att elenergianvändningen i Sverige kommer att öka. Denna utveckling drivs på av bland annat omställningen till elektriska transporter och kan potentiellt leda till kapacitetsbrist i ledningar inom transmissions- och regionnät, framför allt i storstadsområden.

7. 5. Operation planning for power grids with high instalment of dynamically rated components in liberalised electricity markets

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Frida Lundquist; [2022]
   Nyckelord :Multi-interval real-time markets; Dynamic line rating; Optimal Power Flow; Renewable resources; Ramp-rate; Time inconsistency;

   Sammanfattning : The power grid is a complex system that requires detailed planning and operation of the power sources. As renewable resources are increasing their share of the power mix, there are new criterion and aspects to take into account. Renewable resources such as wind and solar power are intermittent and challenge the planning and operation further. LÄS MER
