英文摘要： For the purpose of defending serious disasters, it is necessary to consider the future grid security during planning from the macroscopic view. Therefore, the vulnerability should be considered in the process of power system planning. The differential planning is the foundation of power system security defense system，by focusing on planning and construction of high-standard power grid for key vulnerable nodes and anti-disaster special loads in order to strengthen the overall network. Detailed contents are as follows: power system planning method considering vulnerability, vulnerability assessment of planning project, identification and prediction of anti-disaster special loads and their differential planning for power supply, the key vulnerability nodes identification and their differential planning for power supply, comprehensive backbone network differential planning for important nodes amongst above two kinds of nodes, the relationship between high-standard power grid structure and security of overall network through different planning projects for power supply of different kinds of nodes.The expected results of this project will not only develop self-healing technologies of smart grid, but also have important application value for improving the anti-disaster capacity for defending extreme disaster, and for p
