چکیده انگلیسی
Offshore wind resource assessment seems to be urgently needed due to the rapid development of offshore wind energy in the coming decades. Technical potential of offshore wind energy over the sea area shallower than 250â¯m along China coast is investigated. To avoid erroneous estimation of wind power density, a statistical model considering sea state effect is proposed. Long-term CCMP wind field data are examined using that model to reduce uncertainties. Further, influential factors including wind power density, water depth, wind turbine size, wind farm layout and various spatial constraints are analyzed on the GIS platform. Technical potential under different scenarios are presented and discussed. It shows that wind resource at Taiwan Strait is particularly abundant, where wind power density at 70â¯m height can be above 900â¯W/m2. Technical potential is quite sensitive to the size of wind turbine. Taking the layout S1 (8â¯Ãâ¯15 turbines in each farm, 8 rotor diameters apart between wind turbines, 20â¯km buffer region between neighboring farms) as an example: the total technical potential of the study area is 613â¯GW for rotor radius 60â¯m, and that for rotor radius 90â¯m is 1264â¯GW; the growth rates of technical potential with rotor radius is 19.3â¯GW/m roughly. Spatial constraints has significant impact on the region with water depth less than 50â¯m, where only 48.1% of area is available for developing wind energy and the technical potential there is about 23% of that of the study area.
