TY - JOUR TI - Offshore wind farm electrical design using a hybrid of ordinal optimization and mixed-integer programming JO - Wind Energy A1 - Lumbreras, S., Ramos, A., Sánchez, P. VL - 18 IS - 12 PY - 2015-12-01 PS - 2241 EP - 2258 DO - 10.1002/we.1807 AB - Electrical layout design is, for offshore wind farms (OWF), a complex problem that has a far-reaching impact on both plant cost and reliability. A full optimization of the layout, as opposed to just selecting the most favorable pre-established configuration, is required in order to capture all the potential efficiencies. However, classical optimization methods such as mixed-integer programming (MIP) might not be applicable to large OWFs. This paper describes a novel combination of ordinal optimization (OO) and MIP that is able to deal with large problems in reduced computation times with a statistical optimality guarantee. The algorithm is applied to a real case study taken from Barrow Offshore Wind Farm in the East Irish Sea. ER -
