    Park-level agricultural energy internet: Concept, characteristic and application value

    • The park-level agricultural energy internet has been constructed based on the characteristics of the modern agricultural industrial park. The key problems of park-level agricultural energy internet can be in three aspects: 1) Environment-energy-food synergy security. One of bottleneck problems can be industrial barriers between energy and agriculture. 2) The driving force of agricultural production. Inadequate investment in fixed assets and high energy costs are hindering large-scale agriculture. 3) Intensive and large-scale agricultural production. Cluster agriculture depends on the level of informatization and automation. In the development trends, the park-level agricultural energy internet will gradually realize the deep-level coupling and optimization of heterogeneous energy and agricultural production, while the synergy of agriculture and energy, to promote the development of clean energy but reduce environmental pollution. It is necessary to integrate new energy sources and modern agriculture, to enhance the large-scale operation of agricultural production using new industrial models. The integration of agricultural internet of things (IoTs) and the ubiquitous power IoTs, to shape the intelligent and clustered development of agricultural production. This paper analyzed the development status of park-level agricultural energy internet according to the key problems mentioned before. Then, three typical cases were introduced: One is the use of park-level biomass to achieve the co-production of gas, heat, electricity, and fertilizer; The second is a "complementary of fishery and photovoltaic" industrial model; The third is to achieve intelligent agricultural production through the agricultural Iots. This paper also proposes two key technologies and one operation mode: 1) Agriculture-energy coupling optimization technology. The physical system of park-level agricultural energy internet can be constructed in the way of deep coupling of energy and agriculture, to form the energy structure of "source-net-storage-load". 2) The intelligent technology of agriculture. To form the interaction of ubiquitous power and agricultural Iots, and the information structure of the "perception layer-network layer-platform layer-application layer". 3) Cross-border fusion mode of operation. There is a separation barrier in the mode of the traditional agriculture and energy operation, which can be break via the park-level agriculture energy internet with the cooperation management operation mode, to elevate the agriculture and energy domain trans-boundary fusion. Three features are information sharing, deep coupling, and complementation of production and consumption, with an emphasis on the coupling optimization of multi-energy heterogeneity and agricultural production behavior about industry barriers, meteorological disasters, industrial coupling, cutting-edge technology, and economic cost issues. Finally, the issue has been addressed on the implementation and practice of the framework for the park-level agricultural energy internet.
