  2. 1. From Passive to Active Electric Distribution Networks

    Author : Javier Campillo; Erik Dahlquist; Wu Jianzhong; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active distribution networks; smart grids; smart Meters; real-time pricing; demand-side management; electric vehicles; power systems; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Large penetration of distributed generation from variable renewable energy sources, increased consumption flexibility on the demand side and the electrification of transportation pose great challenges to existing and future electric distribution networks. This thesis studies the roles of several actors involved in electric distribution systems through electricity consumption data analysis and simulation models. READ MORE

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

    Author : David Steen; Chalmers tekniska högskola; []
    Keywords : 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;

    Abstract : 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. READ MORE

  5. 3. Auroral Electric Fields From Satellite Observations and Numerical Modelling

    Author : Tomas Karlsson; KTH; []
    Keywords : Satellite measurements; electric fields; ionosphere; magnetosphere; diverging electric fields; downward current region; black aurora; westward travelling surge; auroral bulge; subauroral ion drifts SAID ; subauroral electric fields SAEF ; mid-latit; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : This thesis is about electrodynamics of thehigh-latitude/auroral region of near-Earth space. The work ismainly based on electric field measurements made by the doubleprobe instrument on the Freja satellite at altitudes ofapproximately 800-1700 km, together with measurements fromother instruments on the same satellite, and ground-basedinstrumentation.

  6. 4. Uncertainty and correlation modeling for load flow analysis of future electricity distribution systems : Probabilistic modeling of low voltage networks with residential photovoltaic generation and electric vehicle charging

    Author : Umar Hanif Ramadhani; Joakim Widén; Joakim Munkhammar; Sarah Rönnberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Probabilistic load flow; Electricity distribution systems; Uncertainty model; Correlation model; Photovoltaics; Electric vehicle; Residential buildings; Hosting capacity; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Abstract : The penetration of photovoltaic (PV) and electric vehicles (EVs) continues to grow and is predicted to claim a vital share of the future energy mix. It poses new challenges in the built environment, as both PV systems and EVs are widely dispersed in the electricity distribution system. READ MORE
