Waveform relaxation for coupled problem
Speaker: Prof. Dr. Ir. Sebastian Schops - TU Darmstadt
Abstract: This talk discusses the application of the waveform relaxation method for the solution of heterogeneous electrotechnical problems. For example problems that consists of electromagnetic fields, electric circuits and controllers as it is the case in the quench protection system of the Large Hadron Collider at CERN, Geneva. Criteria for convergence are discussed and it is shown that a proper choice of the coupling interface speeds up the convergence which can be explained in the framework of optimised Schwarz domain decomposition methods.
Challenges for combining precise and rough models in off-line time-domain power system simulations
Speaker: Dr. Frederic Plumier - Tractebel Engie
Abstract: This talk will present the co-simulation of the two main categories of models used for off-line time-domain power system simulations, namely ElectroMagnetic Transients (EMT) and Phasor Models (PM). The challenges for their combination in a co-simulation framework will be addressed, including the EMT-to-PM and PM-to-EMT conversions, the possible boundary conditions and co-simulation protocols. Illustrative test results on a medium size power system will be presented.
Numerical aspects of FMI for Model Exchange and Co-Simulation v2.0
Speaker: Prof. Dr. Martin Arnold - University of Halle
Abstract: Complex multi-disciplinary models in system dynamics are typically composed of subsystems. This modular structure of the model reflects the modular structure of complex engineering systems. In industrial applications, the individual subsystems are often modelled separately in different mono-disciplinary simulation tools. The Functional Mock-Up Interface (FMI) provides an industrial interface standard for coupling physical models from different domains.
In the present paper, we discuss advanced numerical techniques in co-simulation that are supported by FMI for Model Exchange and Co-Simulation v2.0: Higher order extrapolation and interpolation of subsystem inputs, step size control including step rejection and Jacobian based linearly implicit stabilization techniques.
Power System Co-simulation using AIT LabLink
Speaker: Dr. Jawad Kazmi
Abstract: Power system co-simulation is a complex task presenting many practical challenges. This talk will discuss how some of these challenges are addressed in our co-simulation toolkit that provides the coupling possibilities for both hardware and software components. The talk, after providing a short overview, will discuss various examples demonstrating the applicability and effectiveness of LabLink. There can be a possibility of a short demonstration to further exhibit uniform interfaces and coupling capabilities.
