    Författare :Hannes Hagmar; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; security assessment; neural networks; Dynamic voltage security margin; machine learning; voltage instability prediction; voltage stability;

    Sammanfattning : Voltage instability is a phenomenon that limits the operation and the transmission capacity of a power system. An operation state close to the security limits enables a cost-effective utilization of the system but it could also make the system more vulnerable to disturbances. LÄS MER

  3. 2. Data-driven methods for real-time dynamic stability assessment and control

    Författare :Hannes Hagmar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Machine learning; Security assessment; Neural networks; Optimal control; Dynamic voltage security margin; Voltage instability prediction; Voltage stability; Deep reinforcement learning;

    Sammanfattning : Electric power systems are becoming increasingly complex to operate; a trend driven by an increased demand for electricity, large-scale integration of renewable energy resources, and new system components with power electronic interfaces. In this thesis, a new real-time monitoring and control tool that can support system operators to allow more efficient utilization of the transmission grid has been developed. LÄS MER
