This thesis employs a superconducting magnetic energy storage (SMES) unit and a unified power flow controller (UPFC) as the control systems to perform power flow control and stability improvement of an integrated offshore wind farm and seashore wave energy farm connected to a utility grid. The q-d axis equivalent-circuit model is developed to establish the models for the offshore wind farm, the seashore wave energy farm, the SMES, and the UPFC under three-phase balanced loading conditions. The proportional-integral-derivative (PID) type damping controllers for the proposed SMES and the UPFC are designed using pole-assignment approach based on modal control theory. Steady-state characteristics of the studied system under different values of wind speed, axial velocity of air, and grid voltage are examined. Dynamic simulations of the studied system subject to wind-speed disturbance, axial-velocity disturbance, torque disturbance, and a three-phase fault at the power grid are also carried out. It can be concluded from the simulation results that the proposed two control systems have different effects on power flow control and stability improvement of the studied system
