Study on Plasma Soil Nitrogen Fixation Device for Distributed Photovoltaic Absorption

With the "double carbon" goal put forward, China's rural areas vigorously develop clean energy. Actively build a rural clean energy system. All regions should adjust measures to local conditions to promote the development of rural electrification and the transformation of rural clean energy. However, with the massive access of roof distributed photovoltaic, the rural photovoltaic grid connection consumption problem still exists. It is also necessary to accelerate the local consumption of distributed photovoltaic power generation to improve the overall carrying capacity of rural power grid. For rural areas dominated by grain crops, a green sustainable development model of "PV + modern agriculture" can be built in combination with the location of agricultural areas and regional characteristics. Soil is related to the sustainability of agricultural production. The formation and change of soil fertility play a leading role in soil development and biogeologic cycle. Aiming at the problem of nitrogen loss caused by insufficient soil fertility in some rural areas of China, this paper designed a nitrogen fixation device for atmospheric soil based on low-temperature plasma technology. In cooperation with rural clean energy, a photovoltaic nitrogen fixation technology scheme is proposed. While promoting the consumption of photovoltaic in rural areas, it can also be used to supplement the soil fertility of farmland crops.
