Key Technologies and Applications of Agricultural Energy Internet for Agricultural Planting and Fisheries industry

AbstractWith the complication of energy structure and increment of energy consumption, the convention energy system can no longer fit the situation. The Energy Internet (EI) is proposed to address these issues. The key idea of the EI is that industry system, weather system, traffic system, ecology system, business system, and energy system are coupling with each other to modify the performance of energy system through modern information and communication technologies. In this chapter, the concept of EI is first introduced, and comparisons of the conventional energy system and new energy system are revealed. Then, the integration of different systems with energy system is discussed. Meanwhile, specific approaches with information and communication technologies are introduced.KeywordsEnergy internetNew energy systemEnergy savingEmission reductionEnergy ecology

Research on the climate microenvironment of desert photovoltaic power stations will provide data support for improving the ecological benefits of photovoltaic power stations in desert areas. This study analyzes the temporal variation of the wind field in Qinghai Gonghe photovoltaic industrial park and discusses the impact of photovoltaic development on the wind field and the ecological effects based on the measured data. Our research results show that the wind direction inside and outside the photovoltaic field is relatively dispersed in spring and autumn in terms of seasonal variation. In summer, the wind direction in the photovoltaic field is particularly dispersed, while in winter, the variation of wind direction is that the outside of the photovoltaic field is simpler than the inside. The composition of the main wind direction and the frequency of sand blowing wind are the main factors that lead to the seasonal heterogeneity of the wind field.

Multi-scale impact of large-scale photovoltaic power station construction on wind field in the desert area

In recent years, the photovoltaic industry in desert and Gobi has developed rapidly. In order to reveal the effect of photovoltaic industry on sand prevention and control, this study was performed by taking GuLang Zhenfa photovoltaic DC field on the southern edge of Tengger Desert as an example. Through continuous observation of air temperature, wind speed and air pressure inside and outside the photovoltaic field, combined with the investigation of vegetation inside and outside the photovoltaic field in desert and Gobi of the central and eastern part of Hexi Corridor, this study analyzed the ecological effect of photovoltaic industry on sand prevention and control from three aspects: the balance of surface heat by the transformation of solar radiation of desert photovoltaic, the function of wind barriers and sand barriers of the photovoltaic DC field, and the effect of the photovoltaic DC field on vegetation. The results showed that the photovoltaic DC field in desert and Gobi had very significant ecological functions for desert prevention and control, and the ecological functions were mainly as follows: 1) the photovoltaic DC field could effectively transform solar radiation, adjust the thermal balance of the desert, and weaken the power (i.e., the gale) for the occurrence and development of sandstorms and sand flow; 2) the photovoltaic panel had a strong function of wind barriers, and its function of wind-proof and sand-fixing were several times that of sand barriers; 3) the rain-collecting effect of photovoltaic panel could promote the growth of plants. The development of photovoltaic industry in desert and Gobi not only has remarkable economic benefits, but also has the ecological function of sand prevention and control. China has a vast area of desert and Gobi, and there are broad prospects for the development of desert and Gobi photovoltaic industry. The photovoltaic industry in desert and Gobi is expected to become the third new way of sand prevention and control after afforestation and desertification control and sand fixation by sand barriers.
