Stability Analysis of Power Systems Based on Passivity
This research investigates power system stability using passivity-based analysis. Passivity- based analysis is a method for analyzing transient stability by focusing on energy dissipation within the system. Using this theory, we propose a novel method for estimating the region of attraction for each operating point. The research applies this analysis to design grid-forming (GFM) inverters. GFM inverters are vital for modern power grids with high renewable energy penetration to enhance stability by mimicking traditional synchronous generators. In parallel, we are also exploring the development of a tool that utilizes a mass-spring- damper analogy to provide an intuitive understanding of power system phenomena. This analogy not only allows for an intuitive grasp of how system collapse occurs but also aids in understanding energy functions intuitively.
Speaker – Taku Nishino, Doctoral student at the Tokyo Institute of Technology
These seminars are being delivered by students participating in an exchange program between Tokyo Institute of Technology and Energy, Futures Lab, Imperial College London. The programme offers a unique opportunity for the participants to deepen their academic and cultural understanding over the course of one intensive week. This collaborative initiative is designed to foster cross-institutional learning and innovation in the field of engineering and sustainable energy. The exchange not only aims to enhance technical skills but also to build lasting international connections and a broader perspective on global energy challenges.
