Economic assessment of an innovative farm architecture


Today, most wind farms are connected in Daisy Chain, either in radial or loop configuration. For bottom-fixed farms, either one of these options might be sufficient as the static cables connecting turbines together are mature technologies and are protected from external damage. For floating wind farms, the situation is different because dynami cables are a relatively new technology – all the more so that they are prone to fatigue and external damage. To reduce the risk induced by their introduction, new inter-array architectures, such as the fishbone architecture, can be considered. A techno-economic analysis (TEA) methodology was defined to compare wind farm architectures and highlight the benefits of introducing smart fishbone architectures for floating wind farms.
