➀ The Fraunhofer Institute for Wind Energy Systems IWES has developed a mobile test platform for offshore wind turbines to ensure they comply with grid stability requirements. ➁ The platform, funded by the German Federal Ministry for Economic Affairs and Climate Action, can test turbines up to 28 MVA and is designed for 66 kV offshore voltage levels. ➂ This technology aids in the certification process and supports the transition to renewable energy sources by enabling realistic, full-load tests on large turbines.
