计算和通信能力与电网的集成导致了网络物理系统（CPS）中的许多漏洞。这种网络安全威胁可能会严重影响物理基础设施，经济和社会。在传统的IT环境中，已经有大量的攻击案例表明，未经授权的用户有能力从受保护的网络域访问和操纵敏感数据。电网也大量采用信息技术（IT）来执行实时控制、监控和维护任务。2015年，一场针对乌克兰电网的复杂网络攻击导致大面积停电。它强调了对网络安全投资的重要性。本文提供了一个国家的最先进的调查在电力系统中最相关的网络安全研究。它回顾了展示网络安全风险的研究，并构建了增强电网安全性的解决方案。为了实现这一目标，本文包括：（1）最先进的智能电网技术的调查，（2）电力行业的做法和标准，（3）解决网络安全问题的解决方案，（4）现有的CPS网络安全研究的测试平台的审查，以及（5）未解决的网络安全问题。电网网络安全研究已在华盛顿州立大学（WSU）进行，并使用硬件在环CPS测试平台。提供了一个演示，以显示如何部署拟议的防御系统，以保护电网免受网络入侵者。
The integration of computing and communication capabilities with the power grid has led to numerous vulnerabilities in the cyber-physical system (CPS). This cyber security threat can significantly impact the physical infrastructure, economy, and society. In traditional IT environments, there are already abundant attack cases demonstrating that unauthorized users have the capability to access and manipulate sensitive data from a protected network domain. Electric power grids have also heavily adopted information technology (IT) to perform real-time control, monitoring, and maintenance tasks. In 2015, a sophisticated cyber attack targeted Ukrainian’s power grid causing wide area power outages. It highlights the importance of investment on cyber security against intruders. This paper provides a state-of-the-art survey of the most relevant cyber security studies in power systems. It reviews research that demonstrates cyber security risks and constructs solutions to enhance the security of a power grid. To achieve this goal, this paper covers: (1) a survey of the state-of-the-art smart grid technologies, (2) power industry practices and standards, (3) solutions that address cyber security issues, (4) a review of existing CPS testbeds for cyber security research, and (5) unsolved cyber security problems. Power grid cyber security research has been conducted at Washington State University (WSU) with a hardware-in-a-loop CPS testbed. A demonstration is provided to show how the proposed defense systems can be deployed to protect a power grid against cyber intruders.
