Electrical power systems are very complex systems, which have to be kept stable and secure at all times. Until now, mainly large conventional power plants assure the reliability of the system. Because of the transition to a more sustainable power system, the share of renewable energy sources (RES) is increasing rapidly, and conventional power plants will be replaced. Already today there are times when RES are able to provide 100% of the required energy, but there are still so called must-run conventional power plants for the grid support. Therefore, RES have to assure reliability on their own in the near future.

The i³ project "Verify Green Technologies for Intelligent Grid Control with Power Hardware-in-the-Loop" aims to develop methods to use RES for the provision of grid support by combining volatile generation from wind and solar power plants with storage, which store excessive energy and provide support in times of low generation. Power Hardware-in-the-Loop is used to verify the developed methods using real hardware, like storage and control devices and combine them with simulated grids, including wind and solar generation.

The project started in 2020 and finished in June 2022. It was supported by the I3-Program of the TUHH.
