  2. 1. Cooling Strategies for Wave Power Conversion Systems

    Author : Antoine Baudoin; Cecilia Boström; Anne Blavette; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wave power; power conversion system; thermal management; power elctronics; passive cooling; natural convection.;

    Abstract : The Division for Electricity of Uppsala University is developing a wave power concept. The energy of the ocean waves is harvested with wave energy converters, consisting of one buoy and one linear generator. The units are connected in a submerged substation. The mechanical design is kept as simple as possible to ensure reliability. READ MORE

  4. 2. Planning and Operation of Large Amounts of Wind Power in a Distribution System

    Author : Shemsedin Nursebo; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost benefit analysis; coordination.; distribution system; active management strategies; control; integration issues of wind power; frequency of tap change;

    Abstract : The global installed capacity of wind power has shown a significant growth, from 24 GW in 2001 to 370 GW in 2014. The trend shows that an increasing capacity of wind power is being connected to the electric power system. READ MORE

  5. 3. Efficient Integration of Distributed Generation in Electricity Distribution Networks - Voltage Control and Network Design

    Author : Ingmar Leisse; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Coordinated Voltage Control; Distributed Generation; Electricity meter; PV; Wind Power; Distribution Network;

    Abstract : Distributed generation (DG), i.e. generation connected to the low and medium voltage distribution network (DN), has been increasing a lot during recent years. Thus the traditional assumption of a unidirectional power flow and a voltage decrease along the distribution feeders is no longer valid in all operation conditions. READ MORE

  6. 4. Electricity Distribution Network Planning Considering Distributed Generation

    Author : Yalin Huang; Lennart Söder; Karin Alvehag; Peiyuan Chen; KTH; []
    Keywords : Electricity distribution network; network planning; distributed generation; Electrical Engineering; Elektro- och systemteknik;

    Abstract : One of EU’s actions against climate change is to meet 20% of our energy needs from renewable resources. Given that the renewable resources are becoming more economical to extract electricity from, this will result in that more and more distributed generation (DG) will be connected to power distribution.

  7. 5. Distributed Topology Inference for Power System Applications : Algorithms and architectures utilising industry standards

    Author : Nicholas Honeth; Lars Nordström; Valeriy Vyatkin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substation automation systems; IEC 61850; electrical topology; electrical engineering; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The electrical transmission and distribution system is undergoing unprecedented changes to meet the need for a carbon emission-free global energy system. An expected increase in the portion of end-user energy use in the form of electricity and need to integrate renewable energy sources into the power grid on a large scale require major changes in how power grids are operated and controlled.
