Optimización Técnico-económica del Cableado de Parques Eólicos Marinos

Abstract

[EN] Renewable energy sources are more than ever in the focus of research, funding initiatives and governmental policies. At the heart of this debate is the desire to make such sources cheaper, cleaner and more efficient. Wind generation, in particular, presents a potential that tends to be increasingly exploited and may open the way for the application of new technologies, such as superconductors. In this context, it is pivotal to assess the impact of these innovations. The present study focuses on a fundamental aspect of the design of offshore wind farms: the cabling layout. With new innovations, the main motivation is usually an economic one, to reduce costs. Represented by the Levelized Cost of Energy (LCOE), this study attempts to contribute to an LCOE minimization by proposing a general method that optimizes a cabling layout while maintaining appropriate computational times. This method is, in turn, coupled with a general LCOE minimization algorithm that will be part of another study. The thesis will firstly present a literature review of the most relevant research conducted in this field and will detail the existing gaps that exist. After this, the proposed method of this study is presented in a step-bystem manner and applied to a real-life wind farm which is currently under construction (SaintBrieuc wind farm). An assessment of the cable losses is conducted later on in the power flow section. Finally, a discussion will be conducted and divided into three parts: a comparison of the proposed method with the existing literature, a comparison between the real-life cabling design at St. Brieuc and the method proposed here, and a comparison between the different types of algorithms that could have been used in the proposed solution.

[ES] Después de un estado del Arte de las técnicas de diseño de trazado de cables para parques eólicos marinos, se implementará un algoritmo de diseño de trazado de cables. El algoritmo se acoplará a un algoritmo de optimización para encontrar el trazado de cables óptimo desde el punto de vista técnico- económico y la ubicación óptima de las subestaciones en alta mar. El método se aplicará al parque eólico marino de St Brieuc que se está construyendo en Francia. Los resultados esperados serán útiles para llevar a cabo la evaluación técnico-económica de la energía eólica marina y para estimar su coste nivelado de energía actual y futuro.
