Tutorial: Immittance and Frequency Response of Inverter-Based Resource on 11 Oct in The Hague & virtually

In the morning of 11 Oct 2022, Jian Sun of Rensselaer Polytechnic Institute, USA will present an overview of the theory and different applications of immittance-based frequency-domain modeling and analysis techniques for converters in the grid, with a focus on inverter-based resources (IBRs) such as renewable power?generation and HVDC transmission. This is an intermediate-level tutorial and assumes knowledge of converter circuits and control for IBR applications.

?The term?immittance,?combining the concept of?impedance and admittance, was created by Hendrik W. Bode. Input and output immittances of a converter are a type of transfer functions that define the converter’s frequency response to external disturbances. Immittance modeling and analysis of converters in ac power systems was initially motivated by the need to study converter-based power system stability for electric ship and more-electric aircraft development. The rapid development of renewable energy and HVDC transmission in recent years created an opportunity as well as a need to apply the methods to utility power grids. As a result, a large body of knowledge and a wealth of practical experiences have been developed. Immittance-based frequency-domain modeling now provides a comprehensive framework to study the stability of inverter-based resources (IBRs) and systems. It also enables design engineers to optimize IBRs and their control design for stable operation with/in the grid. New immittance-based IBR performance specifications and system study procedures/tools are also being developed.
