Transmission level harmonics and converter stability in modern power systems
Part 1 – The tutorial “Transmission level harmonics in modern power systems” will present a broad overview of power system harmonic problems in a modern power system, methods of analysing, transmission level measuring and effectively mitigating. Focus of the tutorial is on transmission level modellering with special focus on high voltage power cables dominated power systems and the potential negative effects of harmonic amplification. The tutorial will give a common understanding of the issues and how to address then in practical design cases. Different modelling techniques are presented and advantages and disadvantages discussed. Lastly, a discussion of issues related to transmission level measurement of harmonics is given.
Part 2 – The tutorial “Converter stability in modern power systems” will presents the overview, current status and outline of the multi-frequency stability of converter-based modern power systems. It will address, inter alia, definitions, a state-of-the-art review, and aspects of modelling and analysis methods regarding converter stability in power systems. The tutorial will aim to describe the phenomena, harmonize definitions and explain available methods for analyses with their advantages and disadvantages as well as to provide a common understanding on modelling, analysis, evaluation and mitigation techniques. Furthermore, guidelines on the general approach to such studies and the availability as well as choice of tools will be discussed.
