Horizontal tidal turbine presents important similarities to the wind turbine power systems. Therefore, it would be useful to exploit this similarity to study this important source of energy. In this paper, a new concept of a hybrid offshore windtidal power generation systems coupled electromechanically is studied. Furthermore, a 'time virtual' approach is also presented in order to investigate and compare the energy potentials for given tidal and wind sites. Both the new concept of coupling and virtual time method are simulated in Matlab/Simulink and applyied on Real Time Emulator. Obtained results are presented and disscussed.
