1. 16. Modeling and forecasting the load in the future electricity grid : Spatial electric vehicle load modeling and residential load forecasting

   Författare :Mahmoud Shepero; Joakim Munkhammar; David Steen; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electric Vehicles; GIS; Photovoltaics; Residential Load Forecasting;

   Sammanfattning : The energy system is being transitioned to increase sustainability. This transition has been accelerated by the increased awareness about the adverse effects of the greenhouse gas (GHG) emissions into the atmosphere. The transition includes switching to electricity as the energy carrier in some sectors, e.g. LÄS MER

3. 17. Impact on the Distribution System due to Plug-In Electric Vehicles and Changes in Electricity Usage

   Författare :David Steen; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Plug-in hybrid electric vehicle PHEV ; Electric vehicle EV ; Plug-in Electric Vehicle PEV ; Open loop radial distribution system; Electrical distribution system; Load management;

   Sammanfattning : Replacing conventional vehicles by Plug-in Electric Vehicles (PEVs) would likely increase electricity demand and put higher stress on the electrical power system. This thesis presents an approach to evaluate the impact on electrical distribution systems (DSs) caused by charging PEVs and load management of heating loads. LÄS MER

4. 18. On the thermal inertia and time constant of single-family houses

   Författare :Johan Hedbrant; Björn Karlsson; Mats Söderström; Stig-Inge Gustafsson; Karin Adalberth; Linköpings universitet; []
   Nyckelord :Electric heating;

   Sammanfattning : Since the nineteen-seventies, electricity has become a common heating source in Swedish single-family houses. About one million smallhouses can use electricity for heating, about 600.000 have electricity as the only heating source. LÄS MER

5. 19. Konvertering av direkteluppvärmda flerbostadsområden-Beslutsunderlag och drivkrafter

   Författare :Magnus Stjerndahl; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; weighting methods; residential buildings; energy efficiency; environmental assessment; direct-acting electric heating; incentives; heat supply; heating systems; life cycle cost LCC ; life cycle assessment LCA ; decision making;

   Sammanfattning : The Swedish society is interested in reducing the use of electricity and especially electricity for heating purposes. For this purpose governmental subsidies have been introduced to support a change from electric heating to other types of heat supply systems. Owners of single and multifamily buildings can apply for the investment subsidy. LÄS MER

7. 20. Distribution of Ventilation Air and Heat by Buoyancy Forces inside Buildings : An Experimental Study

   Författare :Claes Blomqvist; Mats Sandberg; Per Heiselberg; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building ventilation; thermal forces; buoyancy; gravity currents; large openings; heating; air quality; forced convection; free convection; Building engineering; Byggnadsteknik;

   Sammanfattning : The main task of the ventilation system in a building is to maintain the air quality and (together with the heating or cooling system) the thermal climate at an acceptable level within the building. This means that a sufficient amount of ventilation air at the appropriate temperature and quality must be supplied to satisfy thermal comfort and air quality demands and that this air is distributed to the parts of the building where people reside.
