Due to the regional differences in the annual utilization hours of wind power in the actual power system, this paper uses the annual utilization hours checking module to screen out the scenarios where the number of
However, wind power generation reached 405.7 billion kWh in 2019, and the ratio of wind power generation accounted for 5.5% of total power generation. The input indicators include wind
The input indicators include wind power installed capacity and wind power utilization hours, the desired output indicator is wind power generation, and the undesired output indicators are
Figure 7. The wind power utilization in this scenario is shown in Figure 8. Fig. 7. Output power of the equipment. Fig. 8. Wind power utilization. (3) The basic scenario with heat storage A heat
Global onshore and offshore wind generation potential at 90m turbine hub heights could provide 872,000 TWh of electricity annually. 9 Total global electricity use in 2022 was 26,573 TWh. 10 Continental U.S. wind potential of 43,000 TWh/yr 9
Utilization hours refer to the annual power produced, divided by rated power. As can be seen from Figure 4, the utilization hours of China's wind power generation equipment fluctuated to a certain extent, with the lowest point of 1724 h in 2015 and the highest value of 2103 h in 2018.
The capacity factor for offshore wind power generation mainly ranges from 0.35 to 0.55 with a higher average, and 38% of wind resources have a capacity factor of more than 0.45 (annual full-load hours of 4,000). Statistical characteristics of technical development scales and capacity factors for global onshore and offshore wind energy
The uncertainty of annual power generation estimation mainly considers the impact of wind resource assessment results, annual operation time, line loss and power generation attenuation, among which the accuracy of wind resource assessment results will also affect the preliminary capacity planning of wind farms.
Nevertheless, in order to further improve the utilization rate of wind resources and energy capture efficiency, the wind power industry is showing a new trend of employing large-scale units, and constructing wind power projects towards high-altitude sites, low wind speed areas and deep and far sea areas .
The lifetime of wind power generation projects can be divided into three categories: design lifetime, natural lifetime and economic lifetime , , . Economic lifetime refers to the working life which gains the lowest average cost. Design lifetime is the effective service time when the wind farm is designed without losing its use function.
Introduction Wind power generation is one of the most mature technologies in the renewable energy field. Benefiting from technological innovation and policy support, the new installed capacity of global wind power is 93.6GW, and the cumulative installed capacity of global wind power has reached 837GW in 2021 .
