This thesis presents the stability-analysis results of a twelve-bus multi-machine power system connected with a hybrid wind and wave power-generation system through a DC link and an inverter using a static synchronous compensator (STATCOM) integrated with a vanadium redox flow battery (VRB). The lead-lag type of power-oscillation damping controller (PODC) for the proposed STATCOM-VRB is designed by using phase-compensation design method to damp low-frequency oscillation of the studied system. The steady-state results under various operating conditions and the eigenvalues of the studied system under different operating conditions of wind speed and wave force are performed. The dynamic and transient simulation results of the studied system under different disturbance conditions are also carried out. It can be concluded from the simulation results that the proposed STATCOM-VRB joined with the designed PODC can effectively suppress low-frequency oscillation of the studied system under different operating conditions.
