Assessment of Wind Energy Potential Based on Metar Data in Malaysia

Abstract

Abstract- Wind energy is one of the fastest developing renewable energy technology. This is due to the vast resource of wind and also a green technology which does not emit any pollutants to the environment. The type of wind data used in this study is METAR data with duration from year 2005 till 2011. In peninsular Malaysia, the METAR data are available at Kota Bharu, Johor Bharu, Langkawi and Kuala Terengganu, while in the state of Sabah and Sarawak are at Sandakan, Miri, Kota Kinabalu, Kuching and Kudat. The wind speed and direction is analyzed using WAsP to generate wind rose chart and weibull distribution together with the wind power density . For wind power analysis, WindPRO software is used to determine annual energy production through simulation by using a single 22 kW rated power wind turbine as well as the capacity factor and full load hour. The result for wind data at 10 m height indicated that Kudat has the greatest wind energy potential in Malaysia with the highest wind power density of 21 W/m2 produced and Weibull scale parameter c of 2.8 m/s with shape parameter k of 1.74. The site also has the highest annual energy production at 14.6 MWh/year as well as highest capacity factor and full load hour at 7.6% and 661 hours/year respectively.
