  2. 2. On Efficient Transmission Balancing Operation Capturing the Normal State Frequency and Active Power Dynamics

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Martin Nilsson; KTH.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Power Dynamics; Frequency Control; Normal State; Power System Balancing; Transmission System Operator; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In an electric power system, there will always be an electric balance. Nevertheless, System Operators (SOs) often uses the term imbalance. Here, the term imbalance refers to the difference between trades and real-time measurements. READ MORE

  3. 3. On Reliability Methods Quantifying Risks to Transfer Capability in Electric Power Transmission Systems

    University dissertation from Stockholm : KTH

    Author : Johan Setréus; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power transmission reliability; power system security; reliability modeling; risk analysis for power systems; power system planning; TECHNOLOGY Electrical engineering; electronics and photonics Electric power engineering; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Elkraftteknik;

    Abstract : In the operation, planning and design of the transmission system it is of greatest concern to quantify the reliability security margin to unwanted conditions. The deterministic N-1 criterion has traditionally provided this security margin to reduce the consequences of severe conditions such as widespread blackouts. READ MORE

  4. 4. Power Electronics for Mitigation of Voltage Sags and Improved Control of AC Power Systems

    University dissertation from Institutionen för elkraftteknik

    Author : Marcio Magalhães de Oliveira; KTH.; [2000]
