Swiss Wind Atlas Platform

In this project, we are developing a concept for a new Swiss Wind Atlas Platform.

Suisse Eole has asked The Swiss Wind Energy R&D Network to develop a concept in order to improve the Swiss Wind Atlas for improved national and cantonal planning purposes. According to information from Suisse Eole, the current version of the Swiss Wind Atlas tends to under-predict the wind resource at some potential wind energy sites compared to the New European Wind Atlas and compared to various wind measurements that exist. The current version of the Swiss Wind Atlas was created with a combination of Swiss weather stations and wind simulations using the simulation tool WindSim, which has a limited accuracy in some regions (±2-4 m/s). This has an enormous effect on energy production predictions used in national and cantonal planning, especially because the power produced by a wind turbine increases with the cube of the wind speed.

The goal of this project is to develop a platform allowing efficient long-term continuous improvement of the Swiss Wind Atlas, and then to improve the wind speed prediction accuracy in 2-3 pre-defined regions of interest to ±1-2 m/s as well as to develop an effective communication strategy for using the new Atlas.

The Swiss Wind Atlas Platform will allow efficient long-term continuous improvement of the Swiss Wind Atlas by interfacing to the planned Swiss Wind Energy Machine Learning Collaboration Platform, which is being developed as part of a separate SFOE-funded project, as shown below The relevant wind measurement and simulation data will be entered into The Swiss Wind Energy Machine Learning Collaboration Platform, and relevant algorithms will be entered into The Swiss Machine Learning Platform. An interface will then be built to the Swiss Wind Atlas Platform, allowing the transfer of processed wind and reanalysis data, processed simulation data and relevant algorithms. Additionally, the relevant regions for detailed analysis as well as old versions of the atlas can be taken as an input. The Swiss Wind Atlas Platform is the core of the platform, containing algorithms to assimilate, compare, validate, interpolate and even connect to simulations. It will then automatically create a new version of the wind atlas.
