In this paper, an approach based on genetic algorithm is presented in order to optimize the electrical layout of the collection system, as well as the positions of the offshore electrical substations of an offshore wind farm subject to some technical constraints. The objective is to minimize the investment part for the wind farm network which affects the price of the kilowatt-hour produced. The wind turbines are connected to the offshore electrical substations in radial network using medium voltage submarine cables with variable sizes. This radial network can have three different types of wind turbines clustering: chain, star or mixed string/star clustering. The presented work is useful during the plan phase of optimal electrical network configuration of an offshore wind farm.
