Offshore pumped storage concept successfully tested

Today, a 3 m diameter hollow concrete sphere has been recovered from the bottom of lake Constance where it had been operated in a 4 week test in a deph of around 100 m. The energy storage and release feature of this novel storage concept could be demonstrated sucessfully, so the principle is now proven experimentally. Currently, the test results are being evaluated to inform and validate the computer models developed by IWES.

Technology or Economy?

This is no question for us. We design solutions for technical and economical problems arising from the transformation of power supply systems.

Electricity – Heat – Transport

The climate protection aims can only be achieved when the transformation of the energy system is cross-sectorally designed and power supply structures are rethought.

Wind, solar, bioenergy or water?

We work on the system integration of all renewables. Our specific focus being on security of supply and grid stability.

New solution to optimization problems of demand response

The deployment of demand response in private households poses complex issues in terms of fulfilling both restrictions of the grid and flexibility constraints of the households. Researchers at Fraunhofer IWES have developed stochastic optimizations based on probabilistic forecasts, which consider these restrictions.

Better Forecasting For Solar And Wind Power Generation

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.
