摘　　要：随着用户的各项需求增长,电网功能逐渐变得多样化,传统电网已经不能满足所需功能,智能电网因其可以与用户进行信息流和电流的双向沟通,可以更加快捷方便地检测电网的故障而受到了青睐,因此越来越多的传统电网正在向智能电网转型。然而转型的同时,智能电网的安全问题层出不穷,拒绝服务攻击、侧信道攻击、虚假数据注入攻击、欺骗、非法访问以及对基础设施造成破坏和攻击等都威胁着智能电网的稳定运行。本文首先介绍了智能电网安全方面的背景和发展,然后针对目前智能电网主要面临的安全威胁进行了分类和阐述,并根据上述威胁提出了设立防火墙、入侵检测系统、访问控制和身份认证等后续相应的保护方案。最后,讨论了未来在更多新能源(风能、太阳能、核能)以及大量物联网设备等接入智能电网后的网络安全防护工作和安全建议。As the needs of users increased,the grid functions gradually diversified.Traditional power grids can no longer meet the required functions.Smart grid is favored for its two-way communication of information flow and electric current with users,and it can detect grid faults more quickly and easily.More and more traditional power grids are transforming themselves to smart power grids.However,the security problems of smart grid also emerge in an endless stream at the same time.Denial of service attacks,side channel attacks,false data injection attacks,deception,illegal access and attack to infrastructure all threaten the stable operation of the smart grid.This paper first introduces the background and development of the smart grid security.Then we classify and expound the main security threats facing the current smart grid,and put forward the subsequent protection schemes such as firewall,intrusion detection system,access control and identity authentication.Finally,we discuss some suggestions,which about the network security protection work after more new energy(such as wind energy,solar energy,nuclear energy)and a large number of Internet of Things equipment are connected to the smart grid in the future.
