能源建模界一致认为，风能将是减少电力部门碳排放的关键途径。本文提出了一种地理空间信息系统方法，用于估计全球海上风电的空间分辨水平化电力成本。由于涡轮机基础技术的成本不同，因此，资本成本的主要空间特征是输电距离（即到电网连接的距离）和水深。高分辨率容量系数是根据几十年的风速数据计算的全球风速自下而上估计的。固定和浮动基础类型的技术丰富的描述允许计算1 x 1 km电网单元的平均电力成本，相对于特定位置的年发电量，并考虑禁区，阵列损耗和涡轮机可用性。这些数据可用于评估全球和各国经济上可行的海上风能潜力，并可作为能源系统模型的输入。(C)2019爱思唯尔有限公司版权所有。
There is strong agreement across the energy modelling community that wind energy will be a key route to mitigating carbon emissions in the electricity sector. This paper presents a Geospatial Information System methodology for estimating spatially-resolved levelised cost of electricity for offshore wind, globally. The principal spatial characteristics of capital costs are transmission distance (i.e. the distance to grid connection) and water depth, because of the disparate costs of turbine foundation technologies. High resolution capacity factors are estimated from a bottom-up estimation of global wind speeds calculated from several decades of wind speed data. A technology-rich description of fixed and floating foundation types allows the levelised cost of electricity to be calculated for 1 x 1 km grid cells, relative to location-specific annual energy production, and accounting for exclusion areas, array losses and turbine availability. These data can be used to assess the economically viable offshore wind energy potential, globally and on a country basis, and can serve as inputs to energy systems models. (C) 2019 Elsevier Ltd.
