1. (1) Advantages of wind energy: huge potential, wide distribution, renewable, and pollution-free.
(2) Disadvantages of wind energy: low density, instability, large regional differences, wide-area dispersion of wind energy, randomness and low energy density!
2. Wind power generation: The advantages of large-scale systems are high system power supply reliability and low operation and maintenance costs. The disadvantage is high system cost. .
The advantages of this small system are that the system has higher power generation, lower system cost, and lower operation and maintenance costs.
The disadvantage is that small wind turbines have low reliability. .
..Due to the strong complementarity between solar energy and wind energy, wind and solar hybrid power generation systems make up for the resource shortcomings of wind power and photovoltaic independent systems
.
Wind engine is an energy conversion device that converts wind energy into mechanical energy.
As shown in Figure 1-4, the wind engine consists of 5 parts:...The disadvantage is that it is difficult to start. ...The capacity of small wind turbines is not large, and the power generally ranges from a few watts to several kilowatts. Most of them have the advantages of simple structure and easy transportation. ...In the utilization of wind energy, energy storage is an important issue. ...
3. The advantages of wind power generation are:
The cost of solar power generation is too high and the technology content is high. Power generation will be affected when the weather is bad;
For wind power generation, the worse the weather, the stronger the wind, and the better the power generation.
Yes, in addition there are imperfect industrial chains and so on.
1. High cost: The cost of wind and solar power has dropped significantly in the past few years, and the trend continues. With the advancement of technology and the effect of scale effect, the equipment costs of wind power and solar power generation are gradually reduced, and the operation and maintenance costs are also reduced. Government support policies and the promotion of market competition will also help further reduce costs.
2. The industrial chain is imperfect: With the rapid development of wind power and solar power generation, the related industrial chains are also constantly improving. More and more companies are getting involved in the wind power and solar energy industries, with technological levels gradually improving, and production efficiency and product quality also constantly improving. The government and industry associations are also strengthening the management and regulation of the industry to promote the healthy development of the industrial chain.
