  1. 1. Model on Demand : Algorithms, Analysis and Applications

    Författare :Anders Stenman; Fredrik Gustafsson; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : System identification deals with the problem of estimating models of dynamical systems from observed data. In this thesis, we focus on the identification of nonlinear models, and, in particular, on the situation that occurs when a very large amount of data is available. LÄS MER

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

    Författare :Mehran Ahsant; Lennart Johnsson; Marty Humphrey; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 3. Demand Side Response : Exploring How and Why Users Respond to Signals Aimed at Incentivizing a Shift of Electricity Use in Time

    Författare :Isak Öhrlund; Cajsa Bartusch; Peter Juslin; Mikael Larsson; Jacopo Torriti; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Demand response; Electricity use flexibility; Time-varying rate; Dynamic pricing; Price-based program; Time-of-use; Demand charge; Real-time pricing; Real-time feedback; Prosumer; Non-price signal; Non-price incentive; Engineering Science with specialization in industrial engineering and management; Teknisk fysik med inriktning mot industriell teknik;

    Sammanfattning : With increased weather-dependent electricity production and electrification at the heart of the ongoing transition away from fossil fuels, peaks in electricity demand are set to increase and become increasingly difficult to meet, which threatens the functioning of the electric power systems that our society depends on. Time-varying electricity rates, which aim to incentivize electricity users to shift their electricity use in time, have been proposed as a key instrument in alleviating grid imbalances and bottlenecks.

  5. 4. Renewable Heat on Demand : High-temperature thermal energy storage: a comprehensive study from material investigation to system analysis via innovative component design

    Författare :Silvia Trevisan; Björn Laumert; Rafael Guédez; Wujun Wang; Kurt Engelbrecht; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiteknik; Energy Technology;

    Sammanfattning : High-temperature thermal energy storage could enable widespread exploitation of renewable energy sources, providing the required energy flexibility. Technology and component development is needed to enhance the storage thermo-dynamic performance, and identify key design features. LÄS MER
