Hydropower is the largest producer of renewable energy in the US More than 60% of the
total renewable generation comes from hydropower. There is also approximately 22 GW of
pumped storage hydropower (PSH). Conventional PSH uses a synchronous generator, and
thus the rotational speed is constant at synchronous speed. This work details a
hydrodynamic model and generator/power converter dynamic model. The optimization of the

Hydropower is the largest producer of renewable energy in the U.S. More than 60% of the total renewable generation comes from hydropower. There is also approximately 22 GW of pumped storage hydropower (PSH). Conventional PSH uses a synchronous generator, and thus the rotational speed is constant at synchronous speed. This work details a hydrodynamic model and generator/power converter dynamic model. The optimization of the hydrodynamic model is executed by the hydro-turbine controller, and the electrical output real/reactive power is controlled by the power converter. All essential controllers to perform grid-interface functions and provide ancillary services are included in the model.
