To solve the complexity issue of power terminal communication access under the background of Energy Internet for smart power distribution and utilization(SPDU)

an SPDU-terminal communication access architecture with integration of multiple technologies is designed. The paper firstly analyzes the features of power terminal communication access. Then

based on analyzing the shortcomings of existed communication architecture

a three-layer SPDU-terminal communication access architecture is proposed

which features multi-network cooperation and autonomy-selfhealing. Finally

technical implementation is fully depicted and the architecture design is proved to be reasonable through the typical terminal access schemes.
