    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand Response; Flexible loads; Building stock energy-use; Bottom-up simulation models; Load profiles; Non-homogeneous Markov-chains; End-user behavior; Lumped capacitance models; HVAC system control; Smart Grid.; Efterfrågeflexibilitet; Flexibla laster; Energianvändning i byggnadsstocken; Botten-upp-simuleringsmodeller; Elförbrukningsprofiler; Icke-homogena Markovkedjor; Slutanvändarbeteenden; Värmedynamikmodellering; Styrning av HVAC-laster; Smarta elnät.;

    Abstract : The electric power systems are currently being transformed through the integration of intermittent renewable energy resources and new types of electric loads. These developments run the risk of increasing mismatches between electricity supply and demand, and may cause non-favorable utilization rates of some power system components. READ MORE

  4. 2. Domestic Heating with Solar Thermal : Studies of Technology in a Social Context and Social Components in Technical Studies

    Author : Magdalena Lundh; Ewa Wäckelgård; Jan-Erik Nielsen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar heating; solar energy; heating system; social components; market actors; interdisciplinary; heat storage; system solution; energy system; hot water; load profiles; socio-technical; Engineering physics; Teknisk fysik; teknisk fysik med inriktningen mikrosystemteknik; engineering science with specialization in microsystems technology;

    Abstract : Research in solar heating has traditionally focused solely on increasing the system efficiency by improving the technical components. In this thesis the technical methodology and system boundaries are widened to connect the technical aspects with market actors that are highly influential on the implementation of solar technology.

  5. 3. Time Domain Methods for Load Identification of Linear and Nonlinear Systems

    Author : Patrik Nordberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inverse problem; ill-conditioning; upper block triangular Toeplitz matrix; regularization; wavelet parameterization; least squares problem; input estimation; time domain; linear and nonlinear systems; load identification;

    Abstract : The automotive industry faces an increasing demand for virtual prototyping to simulate the operation conditions of vehicles and subsystems. Each component, as well as the complete vehicle, must meet the desired design requirements in a time- and cost-efficient development process. READ MORE

  6. 4. Electric Vehicle Charging Impact on Load Profile

    Author : Pia Grahn; Lennart Söder; Ola Carlsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : One barrier to sustainable development is considered to be greenhouse gas emissions and pollution caused by transport, why climate targets are set around the globe to reduce these emissions. Electric vehicles (EVs), may be a sustainable alternative to internal combustion engine vehicles since having EVs in the car park creates an opportunity to reduce greenhouse gas emissions. READ MORE

  7. 5. Uncertainty modeling for load flow and hosting capacity analysis of urban electricity distribution systems

    Author : Umar Hanif Ramadhani; Joakim Widén; Joakim Munkhammar; Bri-Mathias Hodge; Uppsala universitet; []

    Abstract : Urban demographics are changing, with more than half of the global population currently residing in urban areas. Traditionally, cities are often seen as passive energy consumers relying on external centralized systems. Motivated by the need to mitigate climate change, a shift is underway as cities actively shape energy systems. READ MORE
