| 摘要: |
| 面向能源互联网，提出基于柔性直流互联，以交流变压器为核心、直流母线为框架的交直流混合城市配电网互联结构。以能源互联网的目标和特性为准则，说明该种方案符合能源互联网要求，对可再生能源发电具有高兼容性。利用拓扑可视化工具，将传统电网、BA网络以及所提混合配电网结构抽象成拓扑模型，通过随机删除网络结点模拟网络攻击，对以上3种网络进行安全态势分析，证明所提结构具有更强的鲁棒性。 |

| Abstract: |
| An AC-DC hybrid structure of urban distribution network is proposed for the energy internet，which is based on the flexible DC interconnection，taking the AC transformer as the core and the DC bus as the framework. According to the objectives and features of energy internet，the proposed structure meets the requirements of energy internet and is highly compatible with the renewable energy power generation. The topology models of traditional power network，BA network and AC-DC hybrid network are established by the topological visualization tool and the network security situation is analyzed for three established models by the random deletion of network nodes to simulate the network attack. Results verify that the proposed network structure has better robustness. |
