Modern power grids are complex systems where maintaining stability is crucial despite constant disruptions. Nick Miller’s latest blog delves into the challenging world of grid oscillations—how they occur, their impact with new inverter-based technologies, and practical mitigation strategies. Using everyday examples, Nick breaks down these complex issues and offers insights from his work with our partners at ESIG (Energy Systems Integration Group) on the newly released practitioner’s guide for managing oscillations. Explore the blog, as well as the comprehensive guide, to deepen your understanding and find practical solutions.
I've been worrying about power system oscillations most of my professional life. Over the last 2 years, I’ve been collaborating with ESIG (Energy Systems Integration Group) and the Global Power System Transformation Consortium System Transformation Consortium to develop practical resources for better understanding and managing power system oscillations. Their character is changing with increasing amounts of new solar PV, batteries, wind turbines and other inverter-based resources (IBRs), and system operators are having some sleepless nights. I’ve found that people who aren’t immersed in the nuances of power system dynamics find the topic more than a little confusing. In my latest blog, I use some everyday examples to dive into what causes grid oscillations, how things are changing, and practical insights for mitigation. Check out our just released practical guide on oscillations and insights from our recent workshop, both of which have links in the blog
