Research that has been carried out has found that wind speeds in Medan range from 3.5-7.5m\/s, but the energy potential has not been analyzed and evaluated. This research proposes an analysis of the shape factor (k) and scale (c) for wind speed with the Weibull and Rayleigh distribution models using the correlation coefficient (R<sup>2<\/sup>), Chi-Square (\uab53<sup>2<\/sup>), and Root mean square error (RMSE). For this analysis, wind speed data was obtained from the Meteorology, Climatology, and Geophysics Agency for three years, from 2019 to 2021 in Medan. The probability density distribution function (Pdf) is shown in the shape (k) and scale (c) parameters obtained from the data analysis above. These <em>k<\/em> and <em>c<\/em> parameters are very important to observe about the potential for electrical energy produced in Medan. The research results show that the Weibull distribution is better than the Pdf-based Rayleigh distribution. Meanwhile, the results of statistical analysis show that the Weibull distribution is better than the Rayleigh distribution based on R<sup>2<\/sup>. However, on the other hand, the Rayleigh distribution is better than the Weibull distribution based on Chi-Square and RMSE.<\/p><p><strong>Keywords:<\/strong><\/p><p>Wind speed, Weibull and Rayleigh distribution, wind energy potential, R<sup>2<\/sup>, \uab53<sup>2<\/sup>, and RMSE<\/p><p><a href=\"#\"><strong>Received<\/strong>:<\/a> 14 January 2024<\/p><p><a href=\"#\"><strong>Accepted:<\/strong><\/a> 06 February 2024<\/p><p><a href=\"#\"> <strong>Published:<\/strong><\/a> 17 February 2024<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7cc4bbe elementor-widget elementor-widget-button\" data-id=\"7cc4bbe\" data-element_type=\"widget\" data-widget_type=\"button.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<div class=\"elementor-button-wrapper\">\n\t\t\t<a class=\"elementor-button elementor-button-link elementor-size-md\" href=\"https:\/\/seybold-report.com\/wp-content\/uploads\/2024\/02\/Elvyrev.pdf\">\n\t\t\t\t\t\t<span class=\"elementor-button-content-wrapper\">\n\t\t\t\t\t\t<span class=\"elementor-button-icon elementor-align-icon-left\">\n\t\t\t\t<i aria-hidden=\"true\" class=\"far fa-file-pdf\"><\/i>\t\t\t<\/span>\n\t\t\t\t\t\t<span class=\"elementor-button-text\">PDF<\/span>\n\t\t<\/span>\n\t\t\t\t\t<\/a>\n\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-90d993e elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"90d993e\" data-element_type=\"section\" data-settings=\"{&quot;background_background&quot;:&quot;classic&quot;}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-bf1dfbb\" data-id=\"bf1dfbb\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t\t\t<div class=\"elementor-element elementor-element-cd8c1bd elementor-widget elementor-widget-image\" data-id=\"cd8c1bd\" data-element_type=\"widget\" data-widget_type=\"image.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<style>\/*! elementor -
