Abstract

Offshore wind farms' annual energy yield is higher compared to their counterparts at onshore. However, their investment costs are also high due to high capital expenditure cost components such as offshore platform and turbine foundations. Optimally designed collection cable layout can help reduce the overall investment cost. This paper presents a collection cable layout optimization using Travelling Salesman Problem and Genetic Algorithm. The objective function is to reduce the cost of submarine collection cables and their power losses. Two different substation locations are considered for an offshore wind farm with 25 turbines to investigate the effect of different substation locations on the collection cable cost and cable power losses. In addition, the optimum number of feeders is identified together with right cable size (cross-section) for each feeder that minimizes the collection cable costs and power losses. Results show that collection cable costs can be minimized with the optimum cable layout.
