1. 1. Essays on Banking and Portfolio Choice

   Författare :Bo Larsson; Hans Wijkander; Jean-Charles Rochet; Stockholms universitet; []
   Nyckelord :Optimal reserves; Time-diversification; Home bias;

   Sammanfattning : This thesis consists of three self-contained essays in the fields of banking and portfolio choice.Banking and Optimal Reserves in an Equilibrium Model:I address the question of reserves in banking, particularly the fact that reserves are substantially larger than the stipulated reserve requirements by Bank of International Settlements.

3. 2. Demand Flexibility for the Simultaneous Provision of Multiple Services : Tapping the Potential of Controllable Electric Loads for Frequency Reserves and Energy Arbitrage

   Författare :Lars Herre; Lennart Söder; Qiuwei Wu; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aggregator; chance constrained optimisation; demand response; de-mand response provider; demand side management; frequency reserves; load control; stochastic optimization; aggregator; riskbegränsad optimering; efterfrågestyrning; leverantör av efterfrågesvar; efterfrågeflexibilitet; frekvensreserver; laststyrning; stokastisk optimering.; Electrical Engineering; Elektro- och systemteknik;

   Sammanfattning : Power systems with increasing shares of renewable energy sources require sufficient flexibility sources. One source of flexibility for future power systems is constituted by flexible electric loads. The concept of demand response captures the utilization of demand side flexibility to provide services to the power system. LÄS MER

4. 3. Optimization modeling of frequency reserves and inertia in the transition to a climate-neutral electricity system

   Författare :Jonathan Ullmark; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; generation expansion planning; frequency reserves; inertia; Energy system modeling; synthetic inertia; frequency control;

   Sammanfattning : The ongoing transition towards electricity production systems that are dominated by wind and solar power challenge both the traditional strategy for meeting a varying electricity demand and the traditional way of controlling the AC frequency of the electricity grid. This work investigates how frequency reserves (FR) and inertia, as well as inter-hourly variation management interact in the transition to a climate-neutral electricity system. LÄS MER

5. 4. Optimal strategies and information in foraging theory

   Författare :Emma Sernland; Högskolan i Skövde; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Bayesian foraging; information use; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi; NATURAL SCIENCES; NATURVETENSKAP; Other biology; Övrig biologi; Naturvetenskap; Natural sciences; information use; Bayesian foraging; public information; prior information; negative binomial distribution; group foraging; decision-making; information updating; leaving strategy; Ecology; Ekologi;

   Sammanfattning : In this thesis, I present both theoretical and empirical work where we have studied how humans and animals use information in situations where they need to continually update their information on the density of a resource. We have found that the amount of information, and the way the information is presented, are important factors for how well decisions are adapted to current circumstances. LÄS MER

7. 5. Supply disruptions and the allocation of emergency reserves

   Författare :Clas Bergström; Handelshögskolan i Stockholm; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

   Sammanfattning : This dissertation considers a country that faces uncertain and intermittent disruptions of a single import. It focuses on the possibility of stockpiling the good to hedge against the adverse effects of interrupted supplies. LÄS MER
