Posters
Come meet the poster presenters to ask them questions and discuss their work
We would like to invite you to come and see the posters at our upcoming conference. The posters will showcase a diverse range of research topics, and will give delegates an opportunity to engage with the authors and learn more about their work. Whether you are a seasoned researcher or simply curious about the latest developments in your field, we believe that the posters will offer something of interest to everyone. So please join us at the conference and take advantage of this opportunity to learn and engage with your peers in industry and the academic community.
PO070: PASSIVITY EFFECT IN OFFSHORE WIND TURBINES
Xabier Juancorena Saldias, FW DSP - R&D Technology researcher - Converters & Controls - Wind Energy, Ingeteam
Abstract
The integration of inverter-based resources (IBR) on weak grids is an ongoing challenge due to the stability problems. This problem becomes more relevant in remote offshore locations, as the connection to the onshore network often implies power evacuation through direct HVDC or HVAC transmission. Another problem regarding grid integration of offshore wind farms is the high voltage amplification that these farms present, amplifying up to dozens of times the voltage of the converter seen in the point of connection. This is a disadvantage in terms of grid code harmonic emission compliance and requires the connection of filters in the wind farm. In this context, the passivity analysis becomes very useful since it ensures that no unstable interactions between IBRs and the grid are going to take place as long as all the elements in the system have a passive behaviour in the whole frequency range. Furthermore, having a passive impedance (positive resistance) helps at reducing the amplitude of resonances present in the grid, which allows to eliminate or reduce requirements on wind farm filters. Thus, including the passivity criterion in the design of control algorithms allows to improve the performance of the power converter, and facilitates the grid integration of offshore wind farms.
