A set of systematical optimum operational parameters for wind turbines under various wind directions is derived by using combined momentum-energy and blade-element-energy concepts. The derivations are solved numerically by fixing some parameters at practical values. Then. the interactions between the produced power and the influential factors of it are generated in the figures. https://safeersappliancers.shop/product-category/bosch-logixx-hbm56b551b-built-in-double-electric-oven/
