Wind turbines and photovoltaic panels. The combined use of the so-called "wind and solar complementary system" is a strategy to effectively utilize renewable energy.
1.Working Principle
Principles of wind power generation
The wind force is used to drive the windmill blades to rotate, and then the speed increaser is used to increase the rotation speed to prompt the generator to generate electricity. According to windmill technology, power generation can start at a breeze speed of about three meters per second (the degree of breeze).
Photovoltaic power generation principle
The photovoltaic effect at the semiconductor interface is used to directly convert light energy into electrical energy. When the sun shines on the photodiode, the photodiode converts the sun's light energy into electrical energy and generates electric current.
2.How to use it in combination
System composition
Wind-solar hybrid systems generally include wind turbines, solar cell arrays, controllers, battery packs, inverters, cables, supports, and auxiliary components.
Connection method
Photovoltaic power generation panels and wind power generation systems are independent power generation methods. They are not directly connected to each other, but the key equipment of the inverter can be used to connect the two. The purpose of an inverter is to convert direct current from photovoltaic panels and wind systems into alternating current so that the energy can be fed into the grid.In practical applications, multiple photovoltaic panels and wind power systems can be connected to one inverter to further increase power generation
3.Advantages
Good complementarity
Wind energy and photovoltaics are like two brothers and have a complementary relationship. During the day, photovoltaic power generation is large, but at night, wind energy dominates. From the perspective of output, the two complement each other better.
Improve overall power generation efficiency
The combined use of photovoltaic power generation panels and wind power generation systems can make full use of their power generation advantages at different times and under different conditions to improve the overall power generation efficiency.
In summary, the combined use of wind turbines and photovoltaic panels is an effective method to improve overall power generation efficiency. In practical applications, factors such as system composition, connection methods, safety risks, and maintenance costs need to be fully considered to ensure stable operation of the system and efficient power generation.
