From Science Daily:
The sun does not shine and the wind does not blow with constant intensity. This is a problem for the power grid, where the power supply must always match the power demand. In the EWeLiNE project, Fraunhofer and the German Weather Service have been working to develop better models for forecasting the generation of renewable electricity. Now they have launched a platform for transmission system operators to test the new models live.
In the EWeLiNE project, the Fraunhofer Institute for Wind Energy and Energy System Technology (IWES) in Kassel is working together with Germany’s National Meteorological Service in Offenbach. The partners develop mathematical models that produce improved forecasts accurate for each quarter-hour, which show how much electricity Germany’s installed photovoltaic and wind-farm facilities will generate over the next few hours and days. “It’s crucial for us to interconnect both worlds — forecasts of weather and power — more closely than before, tailoring them better to the requirements of the transmission system operators,” says project manager Dr. Malte Siefert of IWES, describing the added value of the new models. These companies operate the major power lines in Germany that make up the 380- and 220-kV high-voltage grid. Transmission system operators are responsible for bringing electricity to consumers, maintaining the power grid, and expanding it as needed.
EnergyForecaster: Testing forecast models live
The project began at the end of 2012. Now the partners are releasing a demonstration platform called the EnergyForecaster, where transmission system operators can try out new forecasting tools live…
