Slides of my speech @ Wind Power for the 21 Century
- held on 25. september 2000 in Kassel
In my speech I would like to compare Intra and Extraeuropean options for an energy supply with wind power. I will give a short inside in the wind energy potentials and point out the change of the temporal behaviour if different catchment areas are used. Thereby we strive the topics of backup and storage needs and the subject of grid capacities. After this I consider wind energy as major source of power production. And last but not least I am going to reflect about a possible combination of climate protection and development aid. | |
Here you can see the potential production of wind energy calculated from data of the European Centre for Medium Range Weather Forecast expressed in FLH. Europe itself has good wind conditions. But its use is limited by the high population density. In a belt 4000 to 5000 km away from Kassel there are also very good wind conditions and in most of the areas the population density is 2 orders of magnitude smaller than for example in Germany. | |
If we now zoom in and have a view on Europe and its neighbourhood we find that the potential production within the shown area only considering Sites with more than 1500 FLH is about 100 times higher than the Need of the European Union and Norway. So it is possible to be quite selective and choose only the better regions. As an example I selected the following. | |
1.) Good wind sites within EU & Norway. (With restrictions due to the high population density.) | |
2.) The Jamal Region with northern Russia. (The calculated production quite good compares with independent calculations of Risø et al. see REFERENCES[4]. | |
3.) Parts of Kazakhstan. (Single measurements see REFERENCES [5] in the text version} confirm these expectations. Another study arrives at significantly higher velocities, from which 4000 FLH at selected sites can be derived see REFERENCES[3]. | |
4.) Southern Morocco (The calculated production is rather conservative. Due to measurements in this region significantly higher production up to 5000 FLH is expected.) | |
5.) Mauritania also has good wind conditions.
To use these potentials we have to have high transport capacities. | |
The European electricity network within and especially between the countries is too weak for very high wind power penetration. This is also true for the connection to Africa.
For example the Net Transfer Capacities from Morocco to Spain with its 350 MW and the 1100 MW from Spain to France would not allow high power transfer. | |
Economically the option of wind power import is interesting even if new transport capacity is included.
But not only the low population density and the low costs of imported wind power are notable. The temporal behaviour of the power production changes with the size of the catchment area. | |
Comparing the monthly mean wind power of the selected European regions and the Demand of the EU & Norway one can see that the fluctuations of the production varies much more than the demand. Europe is a typical winter wind region with maxima in winter and minima in the summer months. | |
Also the monthly means in Southern Morocco vary much more than the demand, but it is a passat wind (tradewind) region with summer maxima. | |
It is obvious that the use of simultaneous production in different regions can much better fit the demand. This shows the black line which represents a combination of the five selected regions.
But not only the long term behaviour changes with the size and selection of the catchment area. (see the production of all regions engaged) | |
