  2. 2. On Development Planning of Electricity Distribution Networks

    University dissertation from Stockholm : Elektrotekniska system

    Author : Viktoria Neimane; KTH.; [2001]
    Keywords : Electric power systems; electricity distribution; planning; risk management; network optimization;

    Abstract : Future development of electric power systems must pursue anumber of different goals. The power system should beeconomically efficient, it should provide reliable energysupply and should not damage the environment. At the same time,operation and development of the system is influenced by avariety of uncertain and random factors. READ MORE

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

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : David Steen; [2012]
    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. 5. The Four-Quadrant Transducer System for Hybrid Electric Vehicles

    University dissertation from Stockholm : KTH

    Author : Erik Nordlund; KTH.; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Electrical Machines; Hybrid Vehicles; Elektroteknik; TECHNOLOGY Electrical engineering; electronics and photonics Electrical engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elektroteknik;

    Abstract : In this thesis a hybrid electrical powertrain called the Four Quadrant Transducer (4QT) has been evaluated through different driving simulations, which later resulted in the manufacture of a prototype.The simulation of a 12 metric ton distribution truck showed that the 4QT system can reduce the fuel consumption by approximately 30 % during the FTP75 drive cycle.
