Periodic Modelling of Power Systems
2001 (English)In: Proceedings of the 1st IFAC Workshop on Periodic Control Systems, 2001, 91-96 p.Conference paper (Refereed)
This paper treats modelling of power systems with converters in a linear time-periodic framework. A power converter is a nonlinear switching device connecting an AC system to a DC system. The converter generates harmonics that might cause instabilities in systems of this kind. About a nominal periodic trajectory the power converter is well described by a periodic gain matrix, whereas the power grids often can be described by linear time-invariant models. Put together they form a linear time-periodic model. It is also shown in this paper how Integral Quadratic Constraints may be used for robustness analysis. To conclude an inverter locomotive is modeled with the described techniques.
