Application of a New Method 'AGM' to Estimate Weibull Parameters for Low Wind Speed

Wind speed estimation for Weibull parameters can be attained using a variety of different methods. As a matter of fact, according to previous research, the outlined method is more effective in areas where the speed is between medium and high. While Malaysia is located within an equatorial region that experiences low wind speeds, the country's natural resources are not restricted in any way. This research is focused on developing a suitable method for forecasting wind speed in low-speed areas due to the findings of the previous research. An investigation has been carried out in order to determine the most effective methods of making predictions to make better decisions. chi(2), the first goodness of fit (GOF) test shows that the new Alternative Graphical Method (AGM) method comes in second place behind the PDM method, with a 7 per cent difference between the two. However, when it comes to the use of the second GOF, known as KS, the AGM method is once again in second place behind PDM, but this time by a significantly smaller margin of 1.8 per cent. As a result, according to the results of the last GOF (AD) also comes in second place, with forecast performance this time 3.7 per cent superior compared to the PDM method. According to these findings, the proposed new method (AGM) achievement is capable of making predictions that are more accurate than those made by existing techniques, which is a significant step forward.
