IEEE PES Live Online: Short-Circuit Calculations and Grid Equivalents

18 October 2023 @ 11:00 am - 12:00 pm

IEEE Power & Energy Society Live Online Learning

Topic: Short-Circuit Calculations and Grid Equivalents of Modern Power Systems with Power Electronics

Presented by: Oriol Gomis-Bellmunt, Professor CITCEA-UPC & Co-founder, eRoots, Josep Fanals-Batllori, CEO & Lead Engineer, eRoots, Jie Song, Postdoc researcher, CITCEA-UPC, Co-founding parterner, eRoots

This webinar:
The rising penetration of power electronics has significantly changed the feature of modern power system. Compared to conventional generators and loads, power electronics converters can operate in various control modes and might saturate the current in case of being overloaded. Such non-linear characteristics of converters’ operation also increases the complexity for computational analysis of power systems. In this webinar, we will introduce several new approaches for the steady-state calculation of power systems with power electronics in both normal operation and short-circuit fault status. Firstly, we will present an effective solver for short-circuit calculations of power systems dominated by power electronics converters considering the converters’ limits. Then, a novel grid-equivalent representation based on voltage-current mapping will be introduced, which could serve as an alternative of conventional Thévenin/Norton equivalents for computational analysis of power systems with power electronics.
