You haven't gotten an answer because the question is too vague. Are you hoping to model the behavior of a pumped storage facility? I am personally familiar with the design and construction of the Raccoon Mountain Pumped Storage Facility. You will need performance curves showing flow, head, power, efficiency, etc. You will then need to create a pumping (filling and emptying) schedule. What do you hope to do or to learn from this effort? Tell us more and you will get replies.

The best way to put a load on a pump of a pump storage hydro power plant for transient analysis is to simulate the load using a dynamic load model. This model should be able to accurately capture the load response to changes in the system operating conditions. To do this, the model should include the following components: 1. A turbine model to simulate the turbine response to changes in the system head or water flow. 2. A pump model to simulate the pump response to changes in the system head or water flow. 3. A hydraulic model to simulate the hydraulic connections between the turbine and the pump. 4. A control model to simulate the response of the system to changes in the system operating conditions. 5. An electrical model to simulate the electrical connections between the turbine and the pump. By incorporating all of these components into a dynamic load model, it should be possible to accurately simulate the load response to changes in the system operating conditions.
