Offshore Wind Farm Layout Optimization Considering the Power Collection System Cost

The paper proposes a method for optimizing the layout of offshore wind farms to increase their efficiency by reducing effect aerodynamic shading, minimizing electrical losses in cable lines system receiving and transmitting energy generated turbines grid power system. task is reduced determining several parameters that define geometric dimensions shape with pre-installed tur-bine locations. This approach, contrast coordinate-wise search method, makes it possible build symmetrical layouts plants, which practice are more convenient terms maintenance operation. Together optimization layout, optimal location transformer substation synthesis scheme joints between plants has been carried out. To solve this problem, heuristic algorithm was used minimum spanning tree restriction on conductivity connections, made realistic schemes adequately assess technical economic characteristics. As results testing proposed methodology example Horns Rev 1 farm have shown, use approach cost 10–12 %. 7–11 % higher than result obtained using MST algorithm, performs construction circuit simplified topology. change size boundaries site resulted an estimated electricity generation 2.3 decrease its 4 When within fixed site, these indicators improved only 2 as compared original scheme.
