1. 1. Modelling Wind Power for Grid Integration Studies

   Författare :Jon Olauson; Mikael Bergkvist; Mats Leijon; Thomas Hamacher; Uppsala universitet; []
   Nyckelord :Wind power; Wind power modelling; Intermittent renewables; Variability; Integration or renewables; Reanalysis data; Power system studies;

   Sammanfattning : When wind power and other intermittent renewable energy (IRE) sources begin to supply a significant part of the load, concerns are often raised about the inherent intermittency and unpredictability of these sources. In order to study the impact from higher IRE penetration levels on the power system, integration studies are regularly performed. LÄS MER

3. 2. Process integration to increase woody biomass utilization for energy purposes

   Författare :Sennai Mesfun; Francesco Fantozzi; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

   Sammanfattning : Woody biomass is an abundant renewable energy resource in Sweden, and the Swedish government has been promoting research and development programs for the exploitation of this resource as a mean to meet the targets on the reduction of the carbon dioxide emissions from the industrial, energy and transportation sectors. This thesis aims at expanding the knowledge on the efficient utilization of the available woody biomass, so that a larger amount of this renewable resource can be used for energy purposes. LÄS MER

   Sammanfattning : The global energy system is undergoing a transformative change towards renewable energies. The share of Renewable Energy Sources (RES) and bioenergy in the world’s primary energy use has increased in the recent years. LÄS MER

5. 4. Increasing the hosting capacity of distributed energy resources using storage and communication

   Författare :Nicholas Etherden; Sami Repo; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Renewable Energy Generation; Energy Storage; Hosting Capacity; Curtailment; Demand Response; Dynamic Line Rating; Power System Communication; Smart Grid; Förnyelsebara energikällor; Energilagring; Acceptansgräns; Kommunikation i kraftsystem; Smarta elnät; Energy Engineering; Energiteknik; Electric Power Engineering; Elkraftteknik;

   Sammanfattning : The use of electricity from Distributed Energy Resources like wind and solar powerwill impact the performance of the electricity network and this sets a limit to theamount of such renewables that can be connected. Investment in energy storage andcommunication technologies enables more renewables by operating the networkcloser to its limits. LÄS MER

7. 5. Strategies, Methods and Tools for Solving Long-term Transmission Expansion Planning in Large-scale Power Systems

   Författare :Desta Zahlay Fitiwi; Lennart Söder; Michel Rivier; Fernando de Cuadra; Andres Ramos; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Transmission expansion planning; uncertainty and variability; optimization; stochastic programming; moments technique; clustering; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Driven by a number of factors, the electric power industry is expected to undergo a paradigm shift with a considerably increased level of variable energy sources. A significant integration of such sources requires heavy transmission investments over geographically wide and large-scale networks. LÄS MER
