Abstract

Abstract:

With the development of agricultural energy internet,replacing fuel with electricity for agriculture production has been taken as an important technical rout to realize carbon peaking and carbon neutrality since it is able to realize carbon emission reduction and improve environmental quality. Based on the enormous load data of modern agricultural industry, the potential of electric energy substitution in agriculture production is analyzed. Then, a low-carbon agricultural system which integrates distributed renewable energy with agriculture production is proposed. The system can control the growth of crops intelligently by digital twin technology, and virtual power plants for agricultural parks can alleviate the impact brought by new energy fluctuation. The agricultural park with the system is of a higher energy utilization efficiency and favorable economic benefits, which is a clean, low carbon and efficient development rout for agricultural energy internet.

Key words: carbon neutrality, agricultural energy internet, renewable energy, electric energy substitution, farming, fishery, animal husbandry, low carbon agriculture, digital twin, virtual power plant
