Wind turbines have gained popularity as one of the efficient micro grid energy generation sources over the years. However, wind energy yield has been greatly impacted by the wind farm wake effect, especially when the size of the wind farm becomes very large. One way to address this challenge is through wind turbine arrangements and their scalabilit...

A hybrid renewable energy system (HRES) offers a feasible solution for electrifying regions where extending the grid is either unstable, impractical, or too costly. The primary challenge in supplying electric power to the academic areas of Hussaini Adamu Federal Polytechnic (HAFEDPOLY) in Kazaure, Nigeria, has been the inconsistent power distributi...
