Frauke Wiese (born in 1982) did a a year of voluntary ecological service in the National Park Wadden Sea. She studied Energy and Environmental Management at the University of Flensburg. In her diploma thesis, she analysed the system conflict between fluctuating wind energy and inflexible base load of coal fired power plants on the example of new coal fired power plants at the feed-in point of offshore wind in Brunsbüttel. After this she continued to be engaged in the topic of the energy transformation. At the NGO „Deutsche Umwelthilfe" she worked as a project manager at the „Forum Netzintegration Erneuerbare Energien" (Grid integration of Renewable Energies Forum). Frauke Wiese is one of the main initiators of the project „baltic sea.pure energy", which demonstrates that energy systems with 100% renewable energies are possible taking a sailing ship as an example. Since April 2010 she is employed at the Chair of Energy and Environmental Management at the University of Flensburg as a member of Professor Hohmeyer.'s research staff. In a "EUM-Team" she investigates what the electricity supply without fossil energies could look like.
Development of a electricity supply model for Germany with high regional and time resolution on the basis of open source programmes for the modelling of renewable energies scenarios.
In Germany, we are in the process of transition from a fossil electricity system to a system based on renewable energies. This transition includes much more than just a change of electricity sources. It is also a system change: The power units are smaller, the number of feed-in units rises and the locations of feed-in are mainly depending on geographical circumstances. Meteorological conditions determine the availability. Moreover, there is a change in the cost structure and the structure of ownership in the electricity supply. Those changes have influence on the requirements on the flexibility of power plants, the electricity market, the grid and the storage demand. This transition has to be represented in a model of the electricity supply. The key question that has to be answered is: Which demands do different energy transition scenarios create on storage, grid and the flexibility of power plants and which measures – without regard of the composition of the renewable scenarios – basic requirements for a secure electricity supply?
A programme for an electricity supply model that does not integrate renewable energies into the old system but accepts the fluctuating feed-in as the backbone of our electricity supply will be designed. The model works with a time resolution of 15 minutes to be able to show the demanded flexibility and the start-up behaviour of the controllable units. Bymeans of a GIS-programme, the wind and solar conditions and the location of power units and demand will be depicted with a high regional resolution. This is necessary to reach comparable data of energy transition scenarios in terms of grid expansion and storage needs. In order to open the model to a broad user group that can use, optimize and expand the model, only open source programs will be used. Furthermore, the model could be used to answer research questions as well as to visualize electricity supply in educational contexts.
