Personal understanding: 1. Wind power generation uncertainty refers to the uncertainty of the wind power utilization rate of the wind farm throughout the year. The time spent on normal maintenance and shutdown of wind turbines is uncertain each year, so the duration of wind energy use of wind turbines throughout the year is uncertain and the amount of electricity produced is uncertain.
2. When selecting a location for a wind power plant, select the location where the wind turbine will be erected. After at least two to four years of accumulating crosswind data in the selected area, use the wind turbine site. selection software to make the selection. After the selection, the wind farm will be completed for at least It will take another two years. During this period, environmental change factors cannot be predicted, so it is also the uncertainty of thehe production of wind energy.
This is my own understanding. . . See if it works·
The so-called flexibility means that the input and output of wind power is relatively flexible. As long as the start-up wind speed is reached, wind power equipment can be put into operation at any time and supply power to the grid. There is no need to put the boiler into operation like thermal energy, which must first preheat, ignite. , circulate water, preheat the steam turbine and start generating electricity. The same applies in the event of an outage. The wind speed is too high or the grid may cut off wind power at any time when needed. Your electricity will not be used and will have no impact on the wind equipment and its operation. . (This only affects electricity generation revenue and reduces the utilization rate)
