Abstract: 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.
