    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system simplification; power system reduction; power system aggregation; power system equivalencing; renewable energy resources; wind power modelling; storage allocation problem; spinning reserve determination; multi-area power system analyses; power system operation and planning; electricity market analysis.; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. LÄS MER

  3. 2. Power System Operation Planning and Wind Power Curtailment : Efficient Methods for Power System Scheduling and Integration Studies of Variable Renewable Energy

    Författare :Elis Nycander; Lennart Söder; Mehrdad Ghandari; Robert Eriksson; Germán Morales-España; Benjamin Hobbs; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Variable renewable energy; wind power integration; production cost model; power-based unit commitment; wind power scenarios; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : To reduce carbon dioxide emissions, variable renewable energy (VRE) sources are replacing conventional fossil-based power plants for electricity generation. Due to the variability and uncertainty of weather dependent VRE sources, there can be situations when it is not possible to accommodate all the available VRE production, and VRE sources have to be curtailed.

  4. 3. On Incentives affecting Risk and Asset Management of Power Distribution

    Författare :Carl Johan Wallnerström; Rajeev Thottappillil; Patrik Hilber; Ulf Sandberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asset management; correlation studies; incentives; investment planning; maintenance planning; power distribution; reliability analysis; risk management; statistical validation; tariff regulation; vulnerability analysis; weather states; Electric power engineering; Elkraftteknik; Mathematical statistics; Matematisk statistik; Industrial engineering and economy; Industriell teknik och ekonomi;

    Sammanfattning : The introduction of performance based tariff regulations along with higher media and political pressure have increased the need for well-performed risk and asset management applied to electric power distribution systems (DS), which is an infrastructure considered as a natural monopoly. Compared to other technical systems, DS have special characteristics which are important to consider. LÄS MER

  5. 4. Optimal Railroad Power Supply System Operation and Design : Detailed system studies, and aggregated investment models

    Författare :Lars Abrahamsson; Lennart Söder; Arnd Stephan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Railway power supply systems (RPSSs) differ mainly from public power systems from that the loads are moving. These moving loads are motoring trains. Trains can also be regenerating when braking and are then power sources. These loads consume comparatively much power, causing substantial voltage drops, not rarely so big that the loads are reduced.

  7. 5. Identifying critical components for system reliability in power transmission systems

    Författare :Johan Setréus; Rajeev Thottappillil; Stefan Arnborg; Patrik Hilber; Liisa Haarla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transmission system reliability; component reliability importance index; Great Britain power system; power flow analysis; system adequacy; system security; system vulnerability;

    Sammanfattning : Large interruptions of power supply in the transmission system have considerable impact on modern society. The goal for the transmission system operator (TSO) is to prevent and mitigate such events with optimal decisions in design, planning, operation and maintenance. LÄS MER
