locating of the jacket type offshore wind turbine with tuned liquid ‎column gas damper for iranian shores

Regarding the high wind potential in the iranian shores, the best ‎place for installing wind turbines ‎is a location away from the beach.in this research, a sample of an offshore wind turbine with a jacketed ‎type foundation equipped with a damper was considered. it is ‎necessary to use a damper system to reduce wind and wave ‎vibrations and ‎lower damage. in this regard, the tuned liquid column ‎gas damper (tlcgd) system which is ‎one of the most effective ‎dampers were used. the best places to install this item in the three shores of iran were ‎examined by considering the data of 26 oceanographic stations. the equations of hydrodynamic and ‎aerodynamic forces acting on ‎this five degrees of freedom sample were ‎obtained, and expanded in matlab with the effects of 10,000 wave and wind data of ‎selected points. equatin was ‎solved by the ode45 ‎function. the main objective of this study is to find suitable locations ‎‎with minimum fluid movement in tlcgd (cm) and the highest power ‎generation capacity ‎‎(w).‎ then, the range of each area was located using the average results of ‎each point and arcgis software. using the theory of multi objective optimization, the optimum points was extracted.‎ the results ‎showed that for the caspian sea, point (‎37.0 n‎, 53.2 e‎) ‎and the surrounding areas in the east and point (‎38.0 n‎, ‎49.4 e‎) and ‎‎26 in the northwest were suitable for installing turbines.
