  5. 19. Modeling, Model Validation and Uncertainty Identification for Power System Analysis

    Författare :Tetiana Bogodorova; Luigi Vanfretti; Konstantin Turitsyn; Francisco Gonzalez-Longatt; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system modelling; model validation; parameter identification; uncertainty identification; Modelica; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : It is widely accepted that correct system modeling and identification are among the most important issues power system operators face when managing instability and post-contingency scenarios. The latter is usually performed involving special computational tools that allow the operator to forecast, prevent system failure and take appropriate actions according to protocols for different contingency cases in the system.
