In order to study uncertainty and intermittent characteristics of wind power and wave power fed to a power grid or supplied isolated loads, this thesis proposes a DC micro grid with a hybrid wind and wave power generation system. The studied system consists of a wind power generator, a wave power generator, a bi-directional DC/DC converter, and a grid-tied inverter. Energy storage devices can be connected to DC side of the bi-directional DC/DC converter. The studied system with the DC micro grid joined with the wind and wave power generation systems is modeled and simulated using Simulink in MATLAB. In time-domain simulations, the steady-state responses of the studied system are performed while the dynamic simulations of the studied system under various conditions are also carried out. To confirm the fundamental operating characteristics of the studied system, a laboratory-scale test platform is established. The experimental results reveal that the studied system can guarantee stable operation and stably supply the generated power to loads or power grid under different operating conditions.
