Overview, Status and Outline of the New CIGRE Working Group C4.49 on Converter Stability in Power Systems.

This paper presents the overview, current status and outline of the new CIGRE working group C4.49 entitled "Multi-frequency stability of converter-based modern power systems". It provides concise definitions, a literature review covering state-of-the-art contributions, and aspects of modelling and analysis methods are discussed and aided by examples based on a proposed benchmark system. The working group's objective is to describe the phenomena, harmonize definitions and explain available methods for analyses with their advantages and disadvantages as well as providing 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 provided by the working group. [ABSTRACT FROM AUTHOR]
