TP IV.2 Reconstruction of the dynamics of offshore wind farm clusters

A sub-project in Innovation Area IV – System-oriented integration and aerodynamics of offshore wind turbines and wind farms

Fluctuations in the wind flow, especially wind ramps, hinder the system-friendly operation of wind farms and electricity trading. Observer-based forecasts in the minute range can support their prediction.

High-resolution lidar wind measurements enable research into the prediction of local wind dynamics on shorter, high-frequency time scales. In this way, lag-induced yield losses and loads could be reduced and system services provided more precisely.

TP II.3 System integration of 70 GW wind

Sub-project in Innovation Area II – Sustainable maritime spatial planning and use of the German Bight

When large wind structures such as low-pressure areas and fronts move through offshore wind farms, this poses a major challenge for the electrical grid due to the scale of the affected power that needs to be integrated.

For this reason, system integration requirements are being defined for the modeling of yields. On this basis, the modeling and analysis methods for the time-dependent analysis of generation potentials are improved.

TP II.2 Consideration of co-utilization potentials

Sub-project in Innovation Area II – Sustainable maritime spatial planning and use of the German Bight

In this sub-project, potentials and obstacles to the co-use of wind energy with other land users (e.g. fishing, military, transport), but also through uses such as wave, tidal or solar energy, are being developed.

Based on interviews with stakeholders from research and industry as well as users of the maritime space, various co-utilization scenarios are also being developed, e.g. for energy conversion and storage.

TP II.1 Modeling for sustainable spatial and land use planning

Sub-project in Innovation Area II – Sustainable maritime spatial planning and use of the German Bight

In this sub-project, needs-based knowledge and recommendations for stakeholders involved in the planning and approval of the further expansion of offshore wind energy will be derived, which not only focus on wind farm efficiency and yields, but also directly include environmental impacts.

In the process, mesoscale modeling approaches for large-scale expansion are being further developed with regard to the resolution of wake effects and improvement of yield calculations.

Subproject I.3 Evaluation of the expansion targets under various techno-economic conditions Scenarios

Sub-project in Innovation Area I – Social and economic issues relating to the expansion of offshore wind energy

The sub-project focuses on an economic assessment of the planned expansion in the German Exclusive Economic Zone, taking into account various techno-economic scenarios with the aim of creating an overall model.

This model can be used to estimate how likely the expansion is under the conditions of land scarcity and plausible co-use compared to its European neighbors and what costs result for industry and society, so that this can be included in the social acceptance considerations.
