R&D Activities

WEPROG's application, the MSEPS system, requires continuous research and development in both meteorological problems as well as computer technology, as the 3D-numerical modelling of the weather is strongly dependent on the computing technology available to solve the numerical functions inside the weather models. The efficiency of the programming source code is also dependent on the processor technology and hence the solvable problem size. The larger the model areas become, the more computing capacity is required. To keep highest performance in a cost effective framework is an ongoing challenge that requires continuous testing and recoding of software to be able to make use of technology advances.

WEPROG is taking on this responsibility together with their partners and collaborators to always be at the forefront of available technology and to be able to deliver continuous improvements over time. The fact that real-time operations are practised with customers on almost all continents is challenging, but also gives a unique opportunity to identify issues and solve problems at places far away from certain target areas, which however may be affected by such problems. One example are the Rocky Mountains in Alberta that have influence on the weather development in Northern Europe. By solving wind flow issues over the Albertan part of the Rockies, not only the Canadian, but also the Danish and German customers will see improvements in forecast quality.

WEPROG also actively participates and coordinates research projects. In fact, the first project and starting point of WEPROG was the MELTRA project (2003-2006), which was funded by the Transmission System Operator for the western part of Denmark ELTRA (now Energinet.dk).

Current and recent projects, where WEPROG is involved

     EARS4WindEnergy - Ensemble?based Approach utilizing a Refined Sodar for Wind Energy applications

AQSystem, Uppsala University, WEPROG and DTU have teamed up and received project funding under the EU Financed Eurostars 3 program. Eurostars is the largest international funding program
for SMEs across EU countries wishing to collaborate on R&D projects that create innovative products, processes, or services for commercialization.

the EARS4WindEnergy project, the partners will collaborate on improving and quantifying the robustness of the AQSystem ground?based remote?sensing SODAR, and also, to improve and validate
its measurement of turbulence intensity.
Further, the unique ensemble weather modelling by WEPROG and the SODAR observations will be fully integrated, allowing two new advantages to emerge.

the integration will lead to higher prediction accuracy in WEPROG’s forecasting products which will enable productivity improvements in existing wind farms O&M, integration of wind power
into the electric grid, and trading and balancing of wind power.

the integration will be used in a hind?casting mode to extend the confidence in the SODAR’s long?range observations if there are dips in availability.

IEA Wind Task 51: Forecasting for the weather driven Energy System

The new Task 51 "Forecasting for the weather driven Energy System" will focus on facilitating communication and collaborations among international research groups engaged in the improvement of the accuracy and applicability of forecast models and their utility for the stakeholders in the wind industry, in the power sector and in the energy system. This Task has the following specific objectives:

- To establish an active, open forum for sharing knowledge among the participants, related IEA Wind Tasks and other related TCPs through workshops, dissemination and communication measures
- To establish and communicate standards and frameworks for the operation and evaluation of forecast model performance
- To identify paths to increased application and utility of forecast information to the task stakeholders
- To advance the knowledge in the entire modelling chain including the uncertainty and related applications and decision making
- To identify most promising areas for new research to improve the quality and utility of forecasts
- To provide guidelines for the implementation of optimal forecasting solutions

WEPROG will be responsible for 2 workstreams and coordinating Workpackae 3:
Uncertainty / probabilistic forecasting & decision making under uncertainty
Uncertainty is inherent in the forecasting of weather driven power generation. In WP3, the integration of forecast uncertainty into power grid management, wind power bidding strategies, and storage operation, will be analysed considering the role of humans (and their perception of uncertainty and risk), costs and benefits of end-users.

Extreme power system events
Weather extremes are a threat to the power system, not only due to destruction of hardware, but also due to inadequate unit commitment, grid planning and available generation units. The challenges are broad. Knowledge and exchange of information on how to forecast extremes and mitigate effects from such extremes are topics in the next phase.

WIKKI - Wind energy short-term forecast based on coupled meso- and microscale models controlled by artificial intelligence (2022-2024)

The aim of the project is to create a process chain from ensemble weather forecasting in connection with CFD modeling and ML-based power forecasting as well as learning and feedback processes to combine micro-, meso- and macroscales into an integrated improved short-term forecast for wind energy applications.

Coordination: Esslingen University of Applied Sciences, Building and Energy Technology (HE-NG)
Partners: Esslingen University, IT and information technology (HE-IN), research association WindForS, WEPROG

Funded by the German Federal Foundation for the Environment (DBU) under Project ID: 37549/01 24/0.

IEA Wind Task 36: Wind Power Forecasting

2016-2019 and 2019-2021

The IEA Task 36 Wind Power Forecasting under the IEA Implementing Agreement for Co-operation in the Research, Development, and Deployment of Wind Energy Systems (IEA Wind) focuses on improving the value of wind energy forecasts to the wind industry. There are three distinct areas of challenge in forecasting wind power. The first is in the continuing effort to improve the representation of physical processes in forecast models through both improved initialization and improved parameterizations. The second area is the representation of uncertainty, the lack of uniform benchmark criteria and the lack of benchmarks or comparison datasets. A third area is representation, communication, and use of these uncertainties to industry in forms that readily support decision-making in plant operations and electricity markets. This Task will facilitate coordination of efforts in all three of these areas and will work to define best practices for model evaluation and uncertainty communication.

Photovoltaics is like wind energy an intermittent source of energy, dependent on the sun to shine. Therefore, it cannot or only to a limited amount be used to cover base load requirements in the energy mix. In a future scenario of Bavaria, where PV covers 25% or more of the electricity demand, it is important that ways and methods are found to manage electricity demand and develop storage possibilities. In first instance this is important for grid stability, in the next step storage will become an important means to make PV generated electricity capable of delivering base load.   
The objective of the project is to develop methods and technologies to enhance the amount of PV and other renewable energies and to enable these energy sources to deliver enery in a sustainable way into the grid.
