Otimização de layout de parques eólicos offshore

Abstract

The wind farms layou optimization problem consists in determinate their optimum configuration considering the maximization of total power extracted and minimization of costs related to the project. The present work proposes to evaluate the effect of winds, through different scenarios associated with different and their probabilities, in the layout optimization problem. Intending to this objective, were used different optimization techniques, such as Bat Algorithm (BA), Grey Wolf Optimizer (GWO) and Sine Cosine Algorithm (SCA), in order to identify the most efficient technique. Due to the complexity, related to the maximum number of possible combinations of the layout problem, consequently region of solutions with local minimums, the resource called chaotic map is applied in the adjust of the search parameters of the optimization methods in order to help the global/local search steps. The performance between basic and chaotic methodologies are compared in terms of convergence and quality of solutions. The proposed Methodology considers the wake effect to determine the number and location of wind turbines in a offshore wind farm. A case study of literature is used to evaluate the proposed methodology.
