This work presents the analysis of dynamic behaviour and power generation of a wind-tidal hybrid system.
Mathematical models and system design approach were used to investigate the feasibility, reliability and
economic impact of the system. From the system design analysis carried out, by harnessing the tidal energy
with wind energy in marine environment, the total power generated (approximately 180KW) by the hybrid
power system showed a significant improvement over a wind turbine system which only generates a
maximum power of 25KW at the rotor diameter as reported in literature. The effects of aerodynamics and
hydrodynamics forces on the structure were investigated through the analysis of dynamic behaviour of the
system under different loads and at various sites in the marine environment. The stability and the optimum
turbine design were found to depend on the wind and tidal speed distribution of the specific site in the
environment. The long term benefit of this work is aimed at meeting the energy needs of coastal dwellers by
implementing the hybrid power system. Also, the gridless system could be used to generate power for both
large and small scale industries in the marine environmen
