Abstract EN
Weibull distribution is the most widely used distribution in wind power assessment.
two parameters weibull distribution is commonly used for wind distribution modeling.
the wind turbine converts wind energy into electrical energy.
according to betz law, no wind turbine can convert more than 59% of the available wind energy into electrical energy.
the available method to find the parameters, e.g., empirical method (EM), method of moment (MoM), energy pattern factor method (EPFM), maximum likelihood method (MLM), modified maximum likelihood method (MMLM), measure an overestimated value of wind power.
an attempt has been made to develop a new method to evaluate weibull parameters to measure wind potential close to the actual one.
the new methods depend on the quartiles of the wind distribution, method of quartile.
wind speed data for twelve months, january to december of 2016, for the cities hyderabad, karachi, and quetta is used in this study.
the new method results are compared with the five methods of weibull parameter determination, EM, MOM, EPFM, MLM, and MMLM.
the new method's average wind speed is closer to the actual average wind speed than those measured by other methods.
the root mean square Error (RMSE), mean absolute error (MABE), and chi-square statistic calculated by all methods are close.
the akaike Information Criterion (AIC) model selection criterion was used for each method and month.
It is found that the AIC values for every month and every city are the lowest for MoQ.
it also suggests that the new method, MoQ, is the best among the existing method.
