OTELLO - Technical operation strategies for economic load and lifetime optimization of wind energy farms

Sensitivity and quality of turbulence intensity from mesoscale models

The turbulence intensity (TI) and its forecast play a decisive role in the operation management strategies, since this has one of the highest influences on the wind turbine service life. The TI is parameterized and calibrated from the existing output values of the weather models. For calibration and quality estimation of the TI forecast model, anemos will develop the TI from mesoscale models with different horizontal resolution and investigate their quality using wind measurements.

In addition, TI is an essential parameter in the assessment of onshore site suitability and especially in the application of high-quality wake models in the context of energy yield calculations for offshore wind farms. Park shading is the largest loss factor for offshore wind farms and is subject to the highest uncertainty. Therefore, the time series of TI should improve the quality of park shading calculations. The objective is to establish mesoscale TI for wind applications. Therefore, the accurate determination of the TI is of great importance to gain the necessary acceptance in the wind industry.

STRAIGHT - Increasing quality and efficiency in yield estimation for wind farms

Increasing the quality of the data basis and determining site-specific power curves for an efficient overall framework

In order to achieve the expansion targets for wind energy set by new government, it is necessary to develop a large number of wind farms in a short time. The basis for wind farm planning at a new site is the estimation of the expected energy yields and the selection of suitable wind turbines.

At present, the yield estimation is subject to high uncertainties. In addition, it is time-consuming and cost-intensive, especially due to the currently required one-year wind measurements. The aim of the project is therefore to enable qualitatively better yield estimates in a shorter time and at significantly lower costs through improvements along the entire process chain. To achieve this goal, procedures are being developed that provide a better data basis (e.g. reanalyses, roughness data) for the wind sector. In addition, innovative procedures from the field of data science such as machine learning or model ensembles are used at various points to enable an accurate estimation of energy yields in a shorter time. The merging of the various methods and data into an overall process enables a high degree of automation of yield assessments in addition to the increase in quality. Ultimately, the project thus creates the basis for a reduction in project risks for planners and project developers. In addition, the developed methods can also be used for more precise regional potential assessments and thus contribute to better planning of wind energy expansion.

anemos is playing a key role in the automation of the overall process in this joint project. Scientifically, anemos focuses on the development of methods for determining the site-specific power curve and time series-dependent loss models for improved yield estimates. Furthermore, anemos analyses and corrects the data basis (wind atlas) with regard to the long-term reference of short-term measurements for relevant seasonal deviations.

WINDAUS – Wind atlas time series for dispersion calculations

Many questions in the area of regional climate and air pollution control or small wind turbines need detailed knowledge about the long-term and representative near-surface wind conditions. These are calculated site-specific with dispersion models or microscale flow models. The main idea of the research project is the processing and the development of closed-meshed high qualitative meteorological data from the anemos wind atlas data for Germany. These data should be able to use for approval processes for dispersion calculations and nationwide air pollution control measures.

SunDAY - Simulation uncertainty of the detailed assessment of wind turbine energy yields

The Uncertainty is one of the important issues when modelling the wind conditions and energy yields of wind turbines. It is a combination of modelling errors (e.g. due to the finite model resolution), model assumptions (e.g. turbulence, stability) and the uncertainty of the input data (terrain data, land use, wind distribution, etc.). Consequently, any type of model is characterized by a certain scope of quality and validity.

In terms of linear models (e.g. WAsP), results of systematic investigations regarding the uncertainty are already available, whereby the site assessment by CFD-Modelling was not investigated in detail so far. The joint research project Sunday aims to fill this gap in the uncertainty of CFD-Modelling. In particular, quantitative knowledge about the dimension of each source of error and about the individual causes will be gained.

Provision of a precise, validated and prepared dataset for the short-term implementation of a wind atlas at the Federal Environment Agency

The main goal of the project is the generation of a proven wind atlas based on ERA5 reanalysis data that is adjusted and corrected with measured data.

As part of the tendering process for onshore wind energy in 2019 and 2020, maximum values ​​for offers will be introduced differentiated by region. The German Environment Agency requires a data basis in order to verify the defined high-value areas appropriately. This is realized by examining the wind conditions.

VERIMA - Verification of Wind and Market Value Atlas for Wind Power

Until recent, the market value atlas depended on the anemos wind atlas, which was based on MERRA-1 reanalysis data (MODERN-ERA RETROSPECTIVE ANALYSIS FOR RESEARCH AND APPLICATIONS) by NASA, a global data set of atmospheric parameters. At the end of 2015, the calculation of the MERRA-1 data was terminated and replaced with MERRA-2 data. As a result, the anemos wind atlas and the market value atlas had to be completely recalculated in order to ensure consistency over the entire time period.

A verification of the market value atlas and an adaptation of the wind atlas to observational data is essential in order to prove their accuracy and to increase the acceptance of these products as well as to extend the number of users. The accuracy of the wind and market value atlas is determined by developing and adopting new modelling methods and comparing the atlas data with wind measurements and energy yield data from wind turbines.

Wind Profile 300 - Validation of two numerical simulation model chains for simulating the vertical wind profiles up to 300 m height above ground

Within this project, numerical simulation models are combined to a model chain which allows for a realistic simulation of the vertical wind profile up to great heights. The models cover the mesoscale (several 10 km) as well as the microscale (several 10 m) and allow for a detailed simulation of the turbulent wind field in the surroundings of planned wind turbines. The new model approaches are evaluated and compared to today's "standard model" WAsP.
