Project Description
The project focuses on stability analysis methodologies for wind turbines. The predominant stability analysis methodology, based on the Multi-Blade Coordinate (MBC) Transformation and a Linear Time Invariant (LTI) dynamic system, used to predict the stability of wind turbines uses many assumptions, some of which are becoming questionable with the ever-increasing size of wind turbines. In this project we explore alternative methodologies based on Linear Time Periodic (LTP) dynamic systems which forego many of those assumptions. The goal is to explore the accuracy advantage of these methodologies and to implement them in a way that is practical and easy for engineers to use, promoting wider adoption within the industry.

Background
I was born in Serres, a small city in northern Greece, and completed my bachelor’s and master’s degrees in Mechanical Engineering at the Aristotle University of Thessaloniki, specializing in machine dynamics and vibrations. As part of my studies, I gained experience through two six-month internships. At BETA CAE Systems, I contributed to software research and development in Statistical Energy Analysis simulations. Later, at MTU Aero Engines, I worked on rotordynamic modeling and simulations using NASTRAN.
Outside of work, I enjoy rock climbing and bouldering, hiking, skiing, and playing the piano.
Motivation
During my studies as a mechanical engineering, I developed an interest in simulating complex physical phenomena. During my master’s thesis I studied the aeroelastic response of a glider wing and developed a strong interest in the field of aeroelasticity. Joining NEXTgenT as a doctoral candidate allows me to continue exploring this field through the development of aeroelastic stability analysis tools for very large wind turbines. I see this project not only as an excellent chance to deepen my expertise in dynamics and simulations, but also as an opportunity to contribute to the advancement of the wind energy field.
