  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. Estimering av efterfrågan på långväga persontransporter : En ekonomisk-teoretisk belysning av gängse modeller samt en ny ansats till uppskattning av efterfrågesamband

    Författare :Thomas Sonesson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Intercity travel demand; gravity model; legit model; entropy maximising; BoxCox; demand elasticities;

    Sammanfattning : This dissertation deals with the estimation of intercity travel demand. The purpose is to discuss the derivations and characteristics of existing models, to derive a demand model based on microeconomic theory and to estimate the parameters of the model in order to gain information on important characteristics of the transport system.

  4. 3. Power to the people : electricity demand and household behavior

    Författare :Mattias Vesterberg; Runar Brännlund; Chandra Kiran Krishnamurthy; Maximilian Auffhammer; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; electricity demand; real-time pricing; demand flexibility; elasticity; appliance-level data; end-use; media; contract choice; de-regulated market; household behavior; intermittent electricity production; efficiency; imperfect information;

    Sammanfattning : Paper [I] Using a unique and highly detailed data set on energy consumption at the appliance-level for 200 Swedish households, seemingly unrelated regression (SUR)-based end-use specific load curves are estimated. The estimated load curves are then used to explore possible restrictions on load shifting (e.g. LÄS MER

  5. 4. Studies in Local Public Transport Demand

    Författare :Johan Holmgren; Jan Owen Jansson; Lars Westin; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Public transport; Demand; Elasticity; Price; Service; Time series; Panel data; Kollektivtrafik; Efterfrågan; Elasticitet; Pris; Trafikutbud; Inkomst; Bilinnehav; Tidsserieanalys; Paneldata; Economics; Nationalekonomi;

    Sammanfattning : This thesis consists of four papers where the overall purpose is to contribute to the understanding of how local public transport demand is affected by different factors. An underlying theme running trough the thesis is the two-way relationship between public transport demand and the service level caused by the fact that capacity and quality are joint products.

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

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

    Sammanfattning : 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. LÄS MER
