The application direction of wind-wind complementarity

Wind solar hybrid power generation technology is a new technology that integrates small and medium-sized wind power technology and solar photovoltaic technology, and integrates various application fields. It involves many fields, has a wide range of applications, and has a wide range of technical differences, which are unmatched by any single technology. Wind energy and solar energy are the most mature, large-scale and industrialized industries in the use of new energy in the world at present. Both wind energy and solar energy have their own disadvantages in development, while wind power generation and solar power generation are complementary. The combination of the two new energies can realize the allocation of natural resources, the integration of technical solutions The comparison between performance and price achieves the most reasonable comprehensive utilization of new energy, which not only reduces the unit cost to meet the same demand, but also expands the market application scope and improves the reliability of products.

In the promotion and application of wind solar complementary power generation technology, the key to competition is the comprehensive configuration capability. Finding the best matching scheme requires a lot of research work, repeated calculation, demonstration, market modeling, component selection, assembly, etc., which has formed the best matching scheme to realize the seamless connection of wind energy and solar energy. When there is light, the solar energy is converted into electric energy through the solar cell, when there is wind, the wind turbine is used to generate electricity, and when there is neither, the load can work using the electric energy stored by the battery.

Wind energy and solar energy are pollution-free and inexhaustible renewable energy sources. Small and medium-sized wind power generation and solar photovoltaic power generation systems have been initially applied in the world. These two power generation methods have their own advantages, but wind energy and solar energy are both unstable and discontinuous energy sources. For use in areas without power grids, it is necessary to equip a considerable amount of energy storage equipment or adopt a multi energy complementary approach to ensure that the power generation system can supply power stably. Solar energy and wind energy have strong complementarities in time and region. China belongs to the monsoon climate region. Generally, the winter wind is strong and the solar radiation intensity is small; The summer monsoon is small and the solar radiation intensity is high, which can be complemented and utilized seasonally. When the sun is at its strongest in the daytime, the wind is very small. At night, after the sun sets, the light is very weak, but the wind energy is strengthened due to the large temperature difference on the surface. Wind power is used to generate electricity at night and in cloudy and rainy days when there is no sunshine, and solar power is used to generate electricity in sunny days. Both of them play a role at the same time when there is both wind and sun, realizing all-weather power generation, which is more economical, scientific and practical than using wind energy and solar energy alone.
