  1. 1. Grid impact study of frequency regulation with EVs

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Emma Blomgren; [2018]
    Nyckelord :Electric vehicles EVs ; grid impact; ancillary services; frequency regulation; FCR-N; vehicle-to-grid V2G ; voltage; reactive power; load profile; Technology and Engineering;

    Sammanfattning : The ongoing grid paradigm shift has resulted in synchronous generators currently being phased out. As the generators have been providing ancillary services, such as frequency control regulation, this means that new technologies to perform ancillary services need to be developed and evaluated.

  3. 2. Förbrukningsflexibilitetens potential och påverkan på kraftsystemet : Med fokus på automatisk frekvensreglering genom styrning av kylskåp

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära; Uppsala universitet/Avdelningen för systemteknik

    Författare :Sandra Ly; Linda Thell; [2015]
    Nyckelord :Demand response; demand management; smart grids; refrigerator; household appliances; frequency control; automatic frequency control; FCR; reserves; Förbrukningsflexibilitet; laststyrning; styrning; smarta elnät; kylskåp; hushållsapparater; frekvensreglering; automatisk frekvensreglering; FCR; reserver; reglerkraft; reglerkraftmarknaden;

    Sammanfattning : Increased use of variable energy and integration of electricity markets in the European Union have led to new challenges when balancing supply and demand in the grid. Load management is a possible way to manage these challenges by adjusting electricity consumption in order to balance the power system. LÄS MER

  5. 4. Analysis of a load frequency control implementation in Swedish run-of-river hydropower stations

    Uppsats för yrkesexamina på avancerad nivå, Elektricitetslära

    Författare :Andreas Westberg; [2012]
    Nyckelord :Hydropower; power system; frequency controlled reserves; load frequency control; Matlab Simulink;

    Sammanfattning : The total amount of frequency deviations have during the last decade increased exponentially in the Nordic synchronous power system. The transmission system operators have therefore decided to implement load frequency control as a new automatic control system to stem these frequency deviations. LÄS MER

  7. 5. ELECTRICAL MODELING OF A THERMAL POWER STATION

    Master-uppsats, KTH/Elektriska energisystem

    Författare :Reinhard Kaisinger; [2011]
    Nyckelord :;

    Sammanfattning : Physical systems are becoming more heterogeneous. Different engineering domainsare interacting more and more. Therefore, it is desirable to have modeling tools that allow multi-domain modeling. In thermal power plants, three engineering domains are of particular relevance: a) thermodynamics, b) mechanics and c) electrical engineering. LÄS MER
