The energy transition to reduce CO2 emissions nowadays is a reality, and renewable energies are a source of clean energy. In this field, Offshore Wind Power Plants (OWPPs) are fast-growing technologies due to their inherent advantages such as no space limitations for large wind turbines, higher and steadier wind speed creating higher energy yields, lower environmental and social impacts, etc. However, the installation and maintenance of large wind turbines in even bigger wind farms and far from the coast suppose high costs. Thus, the investors and engineers aim to reduce costs by the optimization of large wind farms design. The main focus of the present project is given to the electric power system of the AC collection system of an OWPP due to its influence on cost, performance, efficiency and reliability. There are several aspects that can be considered in the optimization process depending on the targeted objectives which in this case are the cable route connection, the substation position and cable cross-section size of the collection system. Besides, the main objective is to reduce the cable investment and annual energy losses of the whole wind farm. For that, a deep literature review is performed from where appropriate optimization methods can be chosen. Finally, two different methodologies are proposed depending on the optimization methods used. The main programs have been implemented in MATLAB software obtaining a decision-making tool for OWPP collection system design
