Yes.
According to the International Energy Network, we learned that renewable energy sources such as photovoltaics and wind power have obvious seasonality and volatility, and an increase in their power generation proportion will inevitably affect the stability of the power system. Photovoltaic power generation is affected by sunlight intensity and angle, and sunlight is strongly related to climate, season, and region. Even changes within a day are extremely obvious and highly random. That is, the power of photovoltaic power generation also has obvious seasonality and fluctuation.
16. What are the advantages of renewable energy power generation such as wind power and photovoltaic power generation in the power system?
The impact of this proportion is as follows:
1. Wind power is usually stronger in spring and autumn, so the wind power generation will be relatively high in these two seasons, while in summer and winter, due to weakened wind, wind power generation will decrease accordingly; photovoltaic power generation It is higher in summer and on sunny days, because the sunshine time is long and the intensity of solar radiation is high. In winter and cloudy days, photovoltaic power generation will decrease.
2. The volatility of wind power and photovoltaic power generation is mainly affected by weather conditions, such as changes in wind speed, cloud cover, etc., which will lead to unstable power generation.
Which one is better, photovoltaic power generation or air power generation?
16. The advantages of renewable energy power generation such as wind power and photovoltaic power generation in the power system are as follows:
1. Solar energy Resources are inexhaustible, and solar energy is widely distributed on the earth. Photovoltaic power generation systems can be used wherever there is light, regardless of region, altitude and other factors.
2. Solar energy resources are available everywhere and can be used to provide power nearby without having to transport them over long distances.
3. The energy conversion process of photovoltaic power generation is simple. It is a direct conversion from light energy to electrical energy. There is no intermediate process and mechanical movement, and there is no mechanical wear.
Both wind power and photovoltaic power generation have the common advantages of being clean, renewable, and never exhausted. Wind power generation has more obvious advantages than photovoltaic power generation. Why do you say this? Mainly based on the following two points:
1. The cleanliness of photovoltaic power generation is relative, because the production of solar panels has the characteristics of high pollution and high energy consumption, and the manufacturing process is not environmentally friendly; while the cleanliness of wind power generation Cleanliness is absolute, which has obvious advantages over photovoltaic power generation!
2. After all, the energy distribution density of photovoltaic irradiation is small. To generate a large amount of electric energy, it takes up a huge area. Therefore, solar power stations generally occupy a relatively large area. A 1GW photovoltaic power station requires an area of 300-400 square meters. acres, so photovoltaic power stations are generally built in remote areas with vast land and sparsely populated land and barren land (it is impossible to build photovoltaic power stations on farmland in densely populated areas). Wind energy power generation facilities occupy a small area and have little impact on normal farming of farmland. Especially offshore wind power does not need to occupy land!
