Weibull Distribution Analysis of Wind Power- Generating Potential on The Southwest Coast of Aceh, Indonesia

Abstract

The National Energy Master Plan sets the target that by 2050 the development of renewable energy for Wind Energy Power Plants reaches 60.647 GW throughout Indonesia, while for Aceh Province, it is predicted that wind energy will be able to generate 894 MW. To map this energy potential, further research is still needed to get the best position for the development of Wind Power Plants. This study aims to map the potential of wind energy in the coastal areas of Southwestern Aceh using the Maximum Likelihood method of the Weibull distribution to analyze wind speed from the data provided by the European Center for Medium-Range Weather Forecast (ECMWF). The area of study covers several districts including Aceh Jaya, Aceh Barat, Nagan Raya, Aceh Barat Daya, Aceh Selatan, Aceh Singkil and Simeulue. The average wind on Weibull distribution for Simeulue is 2.48 m/s with a frequency of 26%, Aceh Singkil 1.54 m/s with a frequency of 40%, Aceh Selatan 1.55 m/s with a frequency of 48%, Aceh Barat Daya 1.55 m/s with a frequency of 50%, Nagan Raya 2 m/s with a frequency of 36%, Aceh Barat 1.54 m/s with a frequency of 38% and Aceh Jaya 2.49 m/s with a frequency of 31%. Meanwhile, the wind power capability ranges from 4,590 watts/m2 - 26,040 watts/m2, making the whole site a low-class wind suitability as a wind power generator.
