1. Lagging power grid construction: The cost of wind power in Inner Mongolia is low, but due to insufficient transmission lines and lagging grid construction, some wind power installed capacity cannot be connected to the grid, resulting in wind curtailment.
2. Unreasonable shutdown and maintenance scheduling: Since wind power generation needs to consider many factors such as grid load, unreasonable shutdown and maintenance and adjustment plans will also lead to an increase in the wind abandonment rate.
3. Lack of flexibility in the construction of wind power projects: Due to the large fluctuations in wind speed in Inner Mongolia, the construction of wind power projects lacks flexibility. For example, some wind power stations adopt a fixed pitch design with a narrow adaptability range, resulting in In certain wind speed ranges, efficient power generation cannot be performed, and wind curtailment is prone to occur.
It is winter, but not for the above reasons
The main reason is that the wind is strong in winter, and maintenance losses and failure losses are greater than in summer. In addition, heavy snow in winter makes maintenance more difficult or Delay. There are also a lot of cut-out losses due to excessive wind speeds.
In addition, due to the power grid, when winds are strong in winter, the output of other wind farms in the same area is also very high, which causes the power grid company to schedule power restrictions.
