Today Hybrid central & QGD OpenFOAM solvers Telegram group (https://lnkd.in/ePEAZ-Xn) counts about 70 people. Not much. But what people are they? They are young researchers, PhD and MSc candidates and developers of open source computational software programs. What do they do? They share their ideas, correct mistakes in source code, input data, mathematical models and physical assumptions. Afterwards, they contribute to the world science with new ideas and guidelines written in their articles and theses, sparking interest in newcomers and helping those who come after them. That's is how the science works from Socrat's times: by sharing personal experience, by cleaning it and making it objective. And that's how open-source paradigm helps the science by providing common software language for computations, common platform for discussions and by creating the environment for professional growth. N.B. Hybrid central (https://lnkd.in/gdspMFHc) and QGD (https://lnkd.in/ewHneWE) OpenFOAM solvers are dedicated for numerical modelling of compressible viscous flows in domains where flows with various Mach and Reynolds values and under various phenomena may interact. #qgd #qgdfoam #hybridcentralsolvers #pimplecentralfoam #openfoam #cfd #gasdynamics

As global electricity needs soar, the shift towards renewable energy sources like wind and solar, supported by storage systems, becomes crucial.

A new article on modeling and fundamental dynamics of #quenching for scalable #perovskite deposition from our team has been published! Congrats to Simon Ternes! "Have you ever wondered why many perovskite researchers talk about supersaturation, but they never exactly determine it? We had the same question, so we developed a versatile open-source software for calculating supersaturation rates in all common quenching techniques."

I am thrilled to share a significant achievement in my thesis project—a Graphical User Interface (GUI) for Windpowerlib is now available on GitHub! ?? Windpowerlib, a robust Python library for wind power plant modelling and analysis, has been at the core of my research. With this user-friendly GUI, my goal was to democratise access to Windpowerlib, making it easier for researchers, engineers, and enthusiasts in the renewable energy sector to harness the power of wind energy. Key Features: ?? Intuitive Interface: Seamlessly interact with Windpowerlib's functionalities through an intuitive GUI, simplifying complex wind power plant simulations. ?? Flexible Configuration: Customise simulation parameters and turbine specifications effortlessly to suit specific project requirements and research objectives. ?? Open Source Collaboration: The GUI is open for collaboration, feedback, and contributions from the global renewable energy community, fostering innovation and collaboration. I invite you all to explore and engage with the Windpowerlib GUI on GitHub, and together, let's accelerate the adoption of wind energy solutions worldwide. GitHub Repository: https://lnkd.in/d8sm8EUS More information and user guide are available in the repository. Thank you for being part of this exciting endeavour, and I eagerly await your feedback and contributions! #RenewableEnergy?#WindPower?#PyQt5?#ThesisProject?#Research? #OEMOF #windenergy

Some useful tutorials for those who want to learn about these tools or just need a refresher.

How can we predict the annual energy losses for wind turbines?with eroded and contaminated blades? A simple way of doing this is to use SALT. This is a prediction tool implemented in Excel and Python and is an abbreviation for Simplified Aerodynamic Loss Tool. Using this tool, you do not need detailed information about the blade geometry etc. You should only find information about 1) rated power, 2) rotor radius, 3) air density, 4) the wind climate described by a Weibull distribution (parameter A and k) and 5) information about the radial position and severity of the blade damages. The damage severity is intended to be determined from inspection images and are described by different categories. These categories are at the moment developed in the LERCat project. You can see a screen dump of the Excel implementation below – and you can download it for free at https://lnkd.in/dK-naP-p. Be aware that damages in the Excel implementation are divided into 2% radial steps and these steps can be varied in the Python version. A description of the method you can find in this paper: https://lnkd.in/dC3y5GKz - and a brief summary of the paper is given by Andreas Bechmann, https://lnkd.in/dwdCED_V)

The US DOE's Solar Energy Technologies Office (SETO) is hosting a series of tutorials on how to access the "Solar Data Bounty Prize" #openaccess datasets. Some examples on how to use #opensource #software to analyze and model some #PV systems will also be demonstrated. The software were developed by the US national labs and the solar community and include: pvlib-python, SAM, RdTools, pvanalytics, solar-data-tools. Sandia's #PVPMC team will demonstrate some of pvlib-python's capabilities in Part 3 of the webinar series.

Thrilled to share another publication on the grid connected converter's control in unbalanced conditions Abstract With the increasing penetration of converter-based power sources into the power system, the performance of the converter has become a key factor for enhancing grid reliability, especially during asymmetrical faults. To meet the low voltage ride-through requirements, the converter should feed the reactive power to the grid for voltage support while ensuring the maximum current limitation for the converter’s safety. For such injections, the grid codes are defined. This paper presents a novel and simplified reference current generation scheme to fulfill the requirement of recent grid codes, ensure the current limit of the converter and confirm better utilization of the converter’s current capacity during asymmetrical faults. Moreover, it also discusses the new sequence extraction scheme based on the delay sample method in the stationary reference frame and the control modifications for the negative sequence current injection. The proposed scheme was tested for different priority injection schemes. Its performance was also compared with other control schemes. Detailed simulation studies, in MATLAB/Simulink, were presented to confirm the performance of the proposed scheme under different faulty conditions. The results confirmed the supremacy of the proposed scheme over the available schemes for better utilization of the converter’s current capacity during asymmetrical faults. It also ensured the peak current limitation of the converter while fulfilling the recent grid code requirements. Moreover, the results showed that the new scheme has 10% more current capacity compared to the other schemes due to better incorporation of the angle between the positive and negative phase sequences of the voltage.
