Renewable and Sustainable Energy Institute (RASEI) Fellow Lucy Pao, from the Department of Electrical, Computer, and Energy Engineering at University of Colorado Boulder, is travelling to Milan, Italy, this December to receive the IEEE Transactions on Control Systems Technology Outstanding Paper Award.

Collaboration Highlight

 

Each year a panel reviews papers nominated from the past two years and selects an article of high significance. The paper, published in 2022, describes the first experimental implementation of Model Predictive Control of the pitch angles of the blades in wind turbines. The Award Ceremony will be held on December 18, 2024, as part of the , held at the Milan Convention Centre in Italy. 

Model Predictive Control (MPC) is an established control technique that is popular in the general control systems community. One of the primary demonstrated applications for MPC is in process chemistry for the large-scale manufacture of pharmaceuticals and commodity chemicals. This describes, for the first time, the application of this technique in the blade pitch control of wind turbines. Control systems in wind turbines are essential for optimizing their performance, ensuring safety, and maximizing energy output. By monitoring key parameters such as blade pitch, rotor speed, yaw angle, and blade root bending moment, the control system can adapt to changing wind conditions, enhancing the efficiency of power generation and reducing mechanical stress on components, helping to extend the turbine’s lifespan.

“MPC is a very nice approach, but it is computationally complex,” explained Lucy. “There is an optimization that needs to be done at every time step, so getting it into a form where we could implement it, was a challenge”.

 

While MPC is a computationally intensive approach, the benefits for wind turbines are significant. Many wind turbine control systems are based on a feedback-only system, where the adjustments are based on feedback of what is happening now. MPC enables preview information to be included, so, for example, you can incorporate knowledge of a gust coming through and the controls can prepare the turbine ahead of time, which can reduce structural loading on that turbine. It changes the control system from simply being responsive to stimuli, to instead being proactive to knowledge of the conditions, essentially letting the wind turbine “see into the future”.

The MPC approach could have significant impacts on how wind turbines are controlled, not only improving their efficiency, but also reducing structural stress on the turbines and extending their lifetimes.

“We are really very excited about this award,” said Pao. “This has been a wonderful collaboration with our colleagues at the for Wind Energy Research in Oldenburg Germany. We started in 2016, with an experimental campaign in 2019 that led to this paper”. Misha Sinner, the lead author of the study, was a graduate student working with Lucy Pao and is now a at the (NREL). Misha travelled to Germany to lead this experimental campaign, and worked together with the team in Germany, led by , to apply MPC to the turbines. “This was a complex experiment to run, and it wouldn’t have been possible without the team of experts and infrastructure at ForWind,” said Misha. “The collaboration has been a really symbiotic relationship; I really value Martin’s input, support, and feedback on the work,” said Lucy.

The collaboration was sparked over a meeting in Stuttgart in 2015. “Martin and I were both external evaluators on a PhD defense for a student at the University of Stuttgart. We had lots of opportunities to chat, and when I mentioned that I was coming up on a sabbatical, he suggested a fellowship that I could apply for that would enable me to work with them,” explained Lucy. This was the start of the long and fruitful collaboration among the team.

There is hope that the recognition that the award brings will accelerate adoption of advanced control systems by the wind energy industry. “MPC can take into account constraints on the wind turbine system, and it is flexible enough to incorporate preview wind information,” said Lucy. This could provide significant improvements in the efficiency and lifetime of future wind turbines. “It is a really nice control framework, and while it has been looked at in the simulation context, it had not been examined experimentally for blade pitch control, to our knowledge,” said Lucy. “We have heard that Industry is looking at MPC, but we don’t know whether it has made it into their actual controllers. The wind turbine industry can be quite secretive about what they are doing”.

The MPC approach could have significant impact on future, and existing wind turbines, by giving the control system the chance to effectively “see into the future” by a couple to tens of seconds so the turbine can prepare itself. “We are very excited and really touched by this award,” emphasized Lucy, with the hope that this will catch the attention of those in the wind turbine industry.

RASEI Graduate Jake Perez (Shaheen Group) and Advanced Thermovoltaic Systems Team Win 2024 Earthshot Prize to Transform Our Planet

Pioneering Energy Solution Converts Industrial waste Heat into Clean Electricity, Revolutionizing Global Energy Use

The Earthshot Prize, inspired by President John F. Kennedy’s “Moonshot” challenge in 1962 to land a man on the moon, was launched by Prince William in 2020 to search for, and scale, the most innovative solutions to the world’s greatest environmental needs. The aim is to unleash the urgent optimism required to accelerate and scale the environmental innovations that will repair and regenerate our planet. In 2024 there were over 5,000 nominations across five categories. One of the 20 winners was the Advanced Thermovoltaic Systems (ATS) team, including Jake Perez, a RASEI alum.

The ATS team was awarded the distinguished 2024 Earthshot “Fix Our Climate” prize for their transformative efforts against climate change. Chosen from 5,342 nominations across 141countries, this prestigious award was recently celebrated at the Earthshot Prize ceremony in Cape Town, that brought together global stakeholders in the fight to save the climate, including Prince William and Sir David Attenborough.

Waste heat is everywhere. Globally, of the energy used to power the industries that the world needs, such as cement and steel, approximately 60% is simply lost as waste. This wasted heat is the equivalent of the energy used by 4 billion homes, twice the number of homes that are on the planet. It is a huge economic and environmental cost. ATS’s revolutionary technology has the potential to redefine the energy sector by tackling the colossal challenge of industrial waste heat, by changing perspectives and considering this ‘waste heat’ as an untapped resource.

ATS has developed a solid-state approach to harness electricity from waste heat, eliminating the resilience on moving parts. This is a shift from traditional turbine-approaches that are complex, have a lot of moving parts and can often rely on hazardous chemicals. The ATS cartridge system is designed for seamless integration across a wide range of industrial applications. You can learn more about the team and the technology that they are developing on this short video.

Congratulations to Jake Perez, who is a RASEI alumni from the Shaheen Group, and the whole team at ATS! Excited to see what is next!
