Ice profile classification - Matthew Wadham-Gagnon
This document summarizes an ice profile classification system based on ISO 12494 that was presented by Matthew Wadham-Gagnon. It describes how TCE measures ice load on its research wind turbines and infrastructure in Quebec, Canada during icing events to classify the ice profile using ISO standards. Metrics like ice thickness, shape, and weight are used to assign ice classes from 1 to 10 for rime ice and 1 to 6 for glaze ice. An example icing event from April 2012 that resulted in ice class 3 to 5 is analyzed using meteorological data and its impact on turbine production. Over
Kvt mapping of_icing
The document describes an icing map of Sweden created using a mesoscale weather model. The map shows the average number of icing hours per year from 2000-2011 at a resolution of 50m x 50m grid cells. The map is available online and can help with siting new wind farms by analyzing potential icing conditions and estimated production losses at different locations. It also categorizes areas into 5 icing classes defined by the IEA to aid in site classification for wind energy projects.
Bergström hans
This document discusses creating an icing climatology using downscaling techniques from a weather modeling project. It examines modeling icing events and ice loads, and comparing modeled results to measurements which sometimes show large differences. Two approaches to the climatology are considered: statistically downscaling long-term low-resolution model runs, or modeling shorter representative periods at high resolution. Both have advantages and drawbacks regarding accuracy and representation of climatological conditions. More research is needed to determine the best approach.

Fredrik Bergström of dcRenewables discusses how to maximize profits from wind power investments in cold climates. He explains that electricity markets are deregulated and pricing is volatile. Risk management involves analyzing risks and ways to handle them such as eliminating, accepting, or controlling risks. The presentation aims to provide insight into profiting from electricity market volatility and maintaining high availability of wind power production.
Byrkjedal øyvind
This document discusses the uncertainty in annual energy production (AEP) estimates for wind farms in cold climates due to variability in wind speeds and icing conditions from year to year. It models the annual production of a sample wind power site under normal conditions and finds an 8.6% standard deviation in production. Factoring in icing, continuing production with iced blades could reduce AEP 9% on average with an 11.6% standard deviation, while stopping turbines during icing could reduce AEP 17% on average with a 14.7% standard deviation. The type of operational strategy during icing affects both the estimated production losses and variability in annual production.
Campbell iain
This document discusses the use of remote sensing devices (RSDs) in cold climates. It finds that RSDs can reliably measure wind shear, turbulence, and extreme winds. At one Swedish site, a Windcube lidar agreed very well with mast measurements and validated the mast's shear profile across the rotor. The document also finds that low turbulence levels do not necessarily lead to an overestimation of energy as seen in some US sites, and that each site should be evaluated individually to determine if an energy loss adjustment is needed. It concludes that deploying an appropriate RSD along with a reference mast can minimize uncertainty and maximize project value.
Davis neil
This document summarizes research on forecasting production losses at a wind farm in central Sweden due to icing conditions. The researchers used observational turbine data, weather research and forecasting (WRF) model output, and an icing model to develop and validate statistical models for predicting hourly wind farm power output. They found that a combination of WRF parameters and icing model outputs best predicted production losses across the three wind parks. Cross-validation showed these statistical approaches improved upon a simple threshold method. Future work will apply the method to additional sites and evaluate forecasts using predicted winds.

The Havsnäs Pilot Project had three main goals: 1) to help remove barriers to large scale onshore wind development in northern Sweden by studying nature impacts, project finance, and foundation design; 2) to research technical areas like high hub heights and cold climate effects; and 3) to improve knowledge of wind resource assessment, power performance, and icing impacts. Key findings included that mast spacing affected flow modelling uncertainty, multi-point shear methods best characterized profiles, and remote sensing validated shear above measurement heights. Icing reduced annual yield by an estimated 4.1%.

Karlsson timo
Indirect detection of ice on wind turbine blades can be achieved by monitoring changes in turbine behavior compared to historical baseline data. Five statistical process control methods were tested that calculate the distance between current and baseline measurements to detect icing. Detection accuracy was highest around 50-80% of rated wind speed and could reach 90% in simulations, but real data testing produced some false alarms. The methods provide a simple ice warning signal without additional sensors by analyzing multiple turbine variables simultaneously.
Lehtomäki ville
This document summarizes ice-induced vibration measurements on MW-scale wind turbines. It presents two case studies from wind farms in Canada and Finland that experienced icing events: (1) A glaze icing event in Canada that resulted in around 5mm of ice accumulation and a 1.5 hour production loss; (2) A rime icing event in Canada that accumulated 15-20cm of ice on the blades. Instrumentation and data from both sites are described, showing increased vibrations and loads on the turbines when icing occurred. The goal is to better understand how icing affects turbine performance and lifetime through increased fatigue loads.

Azure International is a clean energy research and advisory firm based in Beijing. It analyzed operating data from over 5 GW of wind turbines in China, representing 20% of installed capacity from 2006-2011. The analysis found that on average, turbines operated reasonably well with a net capacity factor of 22%, though performance declined over time likely due to grid congestion issues. Individual project performance varied but provided growing evidence that turbines can operate robustly in China despite challenges around curtailment and seasonality.

This document summarizes research on estimating wind power production losses due to icing. Meteorological models are used to calculate icing loads, which are then related to power losses based on comparisons with observed icing loads and production data. Results from the previous winter show generally good agreement between observed and modeled losses at two sites in Northern Sweden when all condensation types are considered. Forecasting power losses from icing hours ahead using mesoscale model output is also discussed.
Ribeiro carla
An investigation was conducted into turbine performance and wind flow modelling under stable atmospheric conditions that are common in the Nordic region. Stable conditions present challenges for wind flow modelling and turbine performance. Complex computational fluid dynamics (CFD) modelling was found to reduce errors in wind flow modelling during stable conditions compared to linear models. Theory and preliminary Nordic data suggest turbine performance is reduced during low turbulence stable conditions, especially at higher wind speeds, though performance recovers in the "knee" of the power curve. More power curve measurement data is needed across the Nordic region to better understand impacts. Site-specific calibration for stable versus unstable conditions may help improve performance estimates.

CAKE: Sharing Slices of Confidential Data on Blockchain
Presented at the CAiSE 2024 Forum, Intelligent Information Systems, June 6th, Limassol, Cyprus.
Synopsis: Cooperative information systems typically involve various entities in a collaborative process within a distributed environment. Blockchain technology offers a mechanism for automating such processes, even when only partial trust exists among participants. The data stored on the blockchain is replicated across all nodes in the network, ensuring accessibility to all participants. While this aspect facilitates traceability, integrity, and persistence, it poses challenges for adopting public blockchains in enterprise settings due to confidentiality issues. In this paper, we present a software tool named Control Access via Key Encryption (CAKE), designed to ensure data confidentiality in scenarios involving public blockchains. After outlining its core components and functionalities, we showcase the application of CAKE in the context of a real-world cyber-security project within the logistics domain.
