This thesis proposes a vanadium redox flow battery (VRB)-based energy-storage system to demonstrate its effectiveness on stability improvement of grid-connected hybrid renewable-energy power-generation systems containing a permanent-magnet synchronous generator-based wind farm and a photovoltaic farm fed to a 12-bus multi-machine power system. The software package is used to establish the model of the proposed VRB to analyze its performance, and the modeling steps for the VRB model are described in detail. The performance and characteristics of an aggregated equivalent model of multiple VRBs are presented, and the aggregated equivalent model’s effectiveness is verified. The steady-state, dynamic, and transient characteritics of an integrated system model with the hybrid renewable-energy power-generation systems, the proposed VRB, and the 12-bus multi-machine system are analyzed. The simulation results show that the proposed VRB-based energy-storage system can offer better performance on power smoothing and stability of the studied integrated system.
