1. 6. Sustainable Electromobility : A System Approach to Transformation of Transportation

   Författare :Harrison John Bhatti; Mike Danilovic; Rune Wigblad; Statens väg- och transportforskningsinstitut; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Energy system; Transportation System; System Approach; Symbiotic Business Model; Innovation Ecosystem; Technology Readiness; Political Readiness; Societal Readiness; Economic Readiness;

   Sammanfattning : This thesis aims to explore, analyze, and develop knowledge that leads to an understanding of identifying the key actors and their symbiotic relationships and dependencies in transforming the energy and transportation system from fossil-based to renewable and fossil fuel-powered vehicles to electric. The research was explorative and categorized into two studies.

3. 7. Inducing large-scale diffusion of innovation : An integrated actor- and system-level approach

   Författare :Ingrid Mignon; Anna Bergek; Johanna Nählinder; Volker Hoffmann; Linköpings universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Innovation; large-scale diffusion; adopters; actor; system; drivers; challenges; motives; strategies; policies; renewable electricity; technology; intermediaries;

   Sammanfattning : In order for the innovation process to be successful, not only do innovations need to be developed and reached the market, but, once they are available for users, they have to spread on a large scale. In the innovation literature, a complete explanation is lacking of why some innovations reach a phase of large-scale diffusion faster than others, including both actor- and system-level components.

4. 8. On Development Planning of Electricity Distribution Networks

   Författare :Viktoria Neimane; KTH; []
   Nyckelord :Electric power systems; electricity distribution; planning; risk management; network optimization;

   Sammanfattning : Future development of electric power systems must pursue anumber of different goals. The power system should beeconomically efficient, it should provide reliable energysupply and should not damage the environment. At the same time,operation and development of the system is influenced by avariety of uncertain and random factors. LÄS MER

5. 9. Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources : Theory and Applications

   Författare :Ebrahim Shayesteh; Lennart Söder; Enrique Acha; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system simplification; power system reduction; power system aggregation; power system equivalencing; renewable energy resources; wind power modelling; storage allocation problem; spinning reserve determination; multi-area power system analyses; power system operation and planning; electricity market analysis.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. LÄS MER

7. 10. On Monte Carlo simulation and analysis of electricity markets

   Författare :Mikael Amelin; Lennart Söder; Hans Ravy; KTH; []
   Nyckelord :Electrical engineering; electricity markets; power systems; monte carlo simulation; Elektroteknik; TECHNOLOGY; TEKNIKVETENSKAP;

   Sammanfattning : This dissertation is about how Monte Carlo simulation can be used to analyse electricity markets. There are a wide range of applications for simulation; for example, players in the electricity market can use simulation to decide whether or not an investment can be expected to be profitable, and authorities can by means of simulation find out which consequences a certain market design can be expected to have on electricity prices, environmental impact, etc. LÄS MER
