An integrated floating energy system consisting of different types of energy devices is an ideal option for reducing the levelized cost of energy by enhancing the power production capacity. This study proposes a concept of an integrated energy system by combining two tidal turbines with a floating wind turbine. In order to investigate the power performance and dynamic responses of the hybrid concept, a novel coupled aero-hydro-servo-elastic tool is developed based on a commercial hydrodynamic analysis software package. In addition, a torque-pitch controller and the AeroDyn module are integrated within the coupled tool for evaluating the power performance of the tidal turbines under dynamic inflow conditions. Experimental data and numerical results obtained by OpenFAST are used to verify the accuracy of the coupled tool in predicting dynamic responses of the integrated energy system. The dynamic responses and power production under different environmental conditions are obtained by conducting a series of simulations. The results indicate that the total power production is increased by 3.84% to 6.46%. The transient behavior of the platform is improved and the tension fluctuation in mooring lines are significantly reduced by the hydrodynamic damping provided by the tidal turbines. In addition, the tidal turbines have no negative influences on the aero-elastic responses and power performance of the wind energy system.The results have demonstrated the advantages of the integrated energy system in enhancing the power production and improving the dynamic performance.

“…The combination of different devices increases the uncertainly of the dynamic response. Some hybrid systems reduce the motion of the platform [138], whereas some do not [123]. Hu et al [122] found that the addition of WECs reduces the maximum horizontal force and pitch moment on the platform, while the maximum vertical force increases due to the PTO force.…”

The urgent demand for energy structural reform and the limitations of single energy development have promoted the combination of wind energy and wave energy. A hybrid energy system means that two or more energy devices share the same foundation. It reduces the levelized cost of energy (LCOE) and improves competitiveness through infrastructure sharing and increased power output. This paper starts with the development of the joint resources of wind and wave energies, then introduces the foundation forms of the hybrid system. It reviews the latest concepts and devices proposed with the integration of wind energy and wave energy, according to the foundation forms, and makes a preliminary assessment of the synergies of the hybrid system. The existing study methods of the hybrid systems are summarized. In view of the challenges faced by the development of hybrid energy systems, several suggestions are put forward accordingly. This paper provides a comprehensive guideline for the future development of the hybrid wind-wave energy converter (W-WEC) system.
