Key Technology and Equipment Development of Multi-mode Integrated Access Terminal for Regional Energy Interconnection

With the development of energy Internet construction, there are more and more intelligent services such as distributed energy access control, “multi meter in one” information collection, electric vehicle charging and discharging orderly control, and the number of devices is increasing. The ubiquitous access of terminals makes the carrying capacity of local communication network difficult to meet the needs of diversified business scenarios. In addition, there are great differences in the underlying connection protocols of the communication network of regional energy internet terminal equipment, which limits the flexibility and reliability of communication, and restricts the realization of interconnection. This paper studies the multi-mode fusion access technology supporting the multi scenario application of intelligent energy, proposes the joint sensing method of regional energy internet terminal services, the mapping, exchange and adaptation method of multi-mode access in terminal layer, and the active networking and routing method of cooperation among terminal nodes, constructs the local intelligent data processing and business fusion model, and develops the multi-mode based multi-mode fusion technology The intelligent internet terminal equipment integrated with communication access technology has established a comprehensive access system for regional energy Internet, and carried out engineering and application pilot.
