  2. 16. Topics in Dynamic Spectrum Access : Market Based Spectrum Sharing and Secondary User Access in Radar Bands

    Author : Miurel Tercero Vargas; Jens Zander; Mikael Prytz; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; spectrum sharing; radar band; cognitive radio; Telecommunication; Telekommunikation; Systems engineering; Systemteknik;

    Abstract : The steady growth in demand for spectrum has increased research interest in dynamic spectrum access schemes. This thesis studies some challenges in dynamic spectrum access based on two strategies: open sharing and hierarchical access. READ MORE

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

    Author : Lars Herre; Lennart Söder; Qiuwei Wu; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 18. On-demand Restricted Delegation : A Framework for Dynamic, Context-Aware, Least-Privilege Delegation in Grids

    Author : Mehran Ahsant; Lennart Johnsson; Marty Humphrey; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Grid Security; Restricted and Context-Aware Delegation; Delegation Protocol; On-demand Delegation; Dynamic Trust Federation; Grid Interoperability; Credential Mapping; Computer science; Datalogi;

    Abstract : In grids, delegation is a key facility that can be used to authenticate and authorize requests on behalf of disconnected users. In current grid systems,delegation is either performed dynamically, in an unrestricted manner, or by a secure but static method. READ MORE

  6. 19. The value of information sharing in automotive supply chains: Understanding the role of information utilisation for operations planning and control

    Author : Paulina Myrelid; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; information sharing; information utilisation; automotive industry; planning processes; information quality; performance; buyer-supplier relationships; operations planning and control;

    Abstract : The purpose of the thesis is to provide knowledge about the role of information utilisation in suppliers’ operations planning and control (OPC) processes, for generating value of shared demand-related information in automotive supply chains. To do so, the thesis focuses on information utilisation from three different perspectives: (1) how suppliers utilise shared information; (2) why they utilise the information the way they do; and (3) the effect of the utilisation.

  7. 20. Modeling and Simulations of Demand Response in Sweden

    Author : Daniel A. Brodén; Lars Nordström; Mikael Amelin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demand response; demand side management; model predictive scheduling; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Electric power systems are undergoing a paradigm shift where an increasing number of variable renewable energy resources such as wind and solar power are being introduced to all levels of existing power grids. At the same time consumers are gaining a more active role where self energy production and home automation solutions are no longer uncommon. READ MORE
