Nonlinear Model Predictive Control of Variable Speed Hydropower for Provision of Fast Frequency Reserves
Tor Inge Reigstad, Kjetil Uhlen
This paper presents the development of a non-linear model predictive controller (MPC) for controlling variable speed hydropower (VSHP) plants. The MPC coordinates the turbine contr…
Variable speed hydropower plant with virtual inertia control for provision of fast frequency reserves
Tor Inge Reigstad, Kjetil Uhlen
In this paper, five virtual inertia control structures are implemented and tested on a variable speed hydropower (VSHP) plant. The results show that all five can deliver fast power…
Modelling of Variable Speed Hydropower for Grid Integration Studies
Tor Inge Reigstad, Kjetil Uhlen
This paper proposes a hydraulic model based on the Euler turbine equations suitable for the purpose of grid integration studies of variable speed hydropower (VSHP). The work was mo…
Optimized Control of Variable Speed Hydropower for Provision of Fast Frequency Reserves
Tor Inge Reigstad, Kjetil Uhlen
This paper deals with the design of controllers for variable speed hydropower (VSHP) plants with the objective of optimize the plants' performance. The control objectives imply ena…
