ABSTRACT
Pumped Storage Hydropower (PSH) is one of the most widely used energy storage technologies globally. It utilizes an upper reservoir to store water, which can later be used during high-demand periods. In the United States, most of the energy storage capacity is attributed to PSH. Additionally, PSH provides multiple benefits to grid operation.
This document presents the Simulink models of three common PSH technologies: Fixed-Speed (FS), Variable-Speed (VS), and Ternary (T)-PSH. These models are available to the general public on this GitHub repository, which contains the MATLAB model initialization files, the Simulink model files, and supplementary MATLAB code used to generate the figures in this study.
For each PSH model, an introductory description of the model components and other relevant functionalities is provided. For further information regarding the models and the initialization parameters, the reader is referred to the shared files in the repository. This document also presents the dynamic behavior of each model. The response of these models to a load event is analyzed and matched with each model’s features. A custom IEEE 39 bus case is employed for the FS and T-PSH simulations, while the VS-PSH is simulated on a simplified three-bus test system due to the computational complexity of the model. For the T-PSH, the steady-state and the switching between several operating modes are also studied in this document.
