Abstract: This work outlines the initial steps of developing digital twin models for hydraulic simulations of a run-of-river pumped storage hydropower system. The study focuses on developing generic river reaches where a chosen set of parameters will be generalized, and the hydraulic behavior and large-scale dynamics of a river caused by pumped hydro will be studied. A parameterization tool has been developed in MATLAB that allows flexible definition of river geometries using parameters such as length, width, depth, slope, shape, meandering and downstream reservoir. The geometries will further be used to run hydraulic simulations using Computational Fluid Dynamics approach where flow velocity, water surface elevation and flow regime will be investigated by varying discharge conditions. Later, the model will also be used to incorporate the dynamics of a pumped storage system. Initial results focus on developing the parameterization tool and understanding the variations in river geometry impacting the hydraulic regime with further simulations intended to optimize run-of-river pumped storage hydropower.
