A Review of Structural Optimization Techniques for Wind Turbines

Abstract

Scientists and researchers are focusing on generation electrical energy using maximum share of renewable energy resources. Wind turbines possess crucial part in generation of electrical energy from renewable energy sources. A lot of research work has been carried out to find out optimum mechanical design of wind turbines specially focused on reduction in weight of turbine blades. This research work presents an extensive review for existing topology optimization techniques specially used for wind turbine blades. At first an indepth review for solid isotropic material with penalization (SIMP) techniques including optimal criteria and filter sensitivity has been presented. After that a comparative analysis focusing advantages and disadvantages of latest optimization techniques that evolutionary structural optimization (ESO) and bidirectional evolutionary structural optimization (BESO) is presented.
