Power-to-heat (P2H) is often mentioned as the solution to decarbonise individual heating. Tomorrow, there will be an opportunity to discuss P2H serving as the solution to decarbonise large-scale district heating systems. As the PGE Energia Ciepła S.A. and Polskie Towarzystwo Elektrociepłowni Zawodowych (#PTEZ) we will share some insights from Gdańsk, where district heating system is fuelled i.a. by heat coming from electrode boilers. We expect a fierce discussion between: Matthieu Ballu, Andrej Jentsch, PhD, Aurélie Beauvais, Dorota Jeziorowska, #Mariusz Michałek moderated by Dave Keating. Power-to-heat is all you need!

Check out the recent Letter in Physical Review Fluids titled "Volumetric visualization of vanishing vortices in wind turbine wakes" from members of our laboratory, Johannes Næsset Hillestad, Srikar Yadala V, Ingrid Neunaber, Leon Li, R. Jason Hearst and Nicholas Worth.   The team investigated the "anomalous" spectral peaks in wind turbine wakes observed in previous experimental studies and field tests. By varying the angles-of-attack of the blades and using time-resolved volumetric measurements (shake-the-box PTV), they quantified tip vortex interactions. Their findings reveal that differences in initial vortex strength lead to unexpected frequency distributions in wind turbine wakes.   You can read this open-access letter at https://lnkd.in/dzVwfrhE.

I recently presented our research outcomes at the Champery Power Conference (https://lnkd.in/e5Y9jHYm, many more amazing talks available), summarising our work from the past few years on stability-constrained optimisation for IBRs-dominated power systems. Our framework is designed to integrate dynamic phenomena (a control challenge) into the steady-state operation of power grids (an optimisation problem). This integration not only ensures minimum operational costs with a guarantee of stability but also facilitates the online co-design of IBRs' dynamic behaviour, moving towards a software-defined grid (SDG). This framework effectively links the stability challenges with economic consequences and can be potentially used to inform the designs of IBRs for the vendors, the investment decisions for the asset owners, and the stability market design and operation for the operators. We are continuing this line of research under the newly established Global Centre: The Electric Power Innovation for a Carbon-free Society (EPICS) - https://lnkd.in/enUpumh4. We are keen to engage in any relevant discussions on this topic. Please do get in touch!

Dear Connections, We have recently published some papers at the North American Power Symposium 2024! These works delve into cutting-edge topics like genetic algorithm-based unit commitment, reliability, resilience, and the use of Real-Time Digital Simulation (RTDS) in advancing power systems. Our research provides insights into optimizing power system operations, enhancing grid resilience, and leveraging simulation tools like RTDS to address real-world challenges in the energy sector. We hope these findings inspire further discussions and innovations in power system reliability and resilience.

The sites where we thickened the ice are clearly visible on our timelapse camera! During our field test at Svalbard in April, we pumped water on top of the sea ice. With remote measurement equipment, we are following the melting process, vs a reference site on the same ice. We do this to validate the impact potential of ice thickening in terms of making the sea ice last longer in summer. We are also continually measuring incoming and reflected solar radiation. For a long time, the Albedo (% reflected) was quite stable at 70%, both for the reference site as for the thickened site. By beginning of June, this was down to around 60% for the thickened site, vs only 35% for the reference site, so a clear difference in reflectivity! The real difference will of course come when the thickened ice really lasts longer, which we will closely follow. The field test was conducted together with Aleksey Shestov of The University Centre in Svalbard and Tim C. Hammer, Laura van Dijke and Hayo Hendrikse of Delft University of Technology
