Dynamic Water-Level Regulation at Run-of-River Hydropower Plants to Increase Efficiency and Generation

In times of the energy transition and the intensified expansion of renewable energy systems, this article presents an optimization approach for run-of-river power, i.e., dynamic water-level regulation. Its basic idea is to use river sections influenced by backwater more evenly via the operating regi...
