Threat analysis of offshore wind farms by Bayesian networks - a new modeling approach

Abstract

As a result of the ongoing commitment to climate protection in more and more countries and the corresponding expansion of renewable energies, the importance of renewables for the security of electricity supply is increasing. Wind energy generated in offshore wind farms already accounts for a significant share of the energy mix and will continue to grow in the future. Therefore, approaches and models for security assessment and protection against threats are needed for these infrastructures.Due to the special characteristics and geographical location of offshore wind farms, they are confronted with particular challenges. In this context, this paperoutlines how an approach for threat analysis of offshore wind farms is to be developed within the framework of the new research project "ARROWS" of the German Aerospace Center. The authors first explain thestructure of offshore wind farms and then present a possible modeling approach using Qualitative function models and Bayesian networks.
