Uniper wanted to investigate implications when their hydro power plants need to renew FCR tests according to new requirements. Will it still be possible to qualify both FCR-N and FCR-D? Will the volumes change? Will the mechanical wear increase due to tougher controller settings?
I have performed complete set of tests in Hjälta (Francis) and Edensforsen (Kaplan) using default control parameters. After testing the power plants were modelled, simulations performed and then FCR tests were repeated with new control parameters.
