近年来，物联网的指数级增长创造了一个越来越大的网络攻击面，为所有计算机化系统引入了新的安全漏洞。这些系统中最重要的是由许多网络物理组件组成的工业控制系统，智能电网是工业控制系统的一个突出例子，其故障有可能在我们日常生活的各个方面造成重大中断。在本文中，我们提供了一个智能电网网络安全标准的概述，并审查在物理，网络和应用层的智能电网环境的主要威胁。为了克服目前缺乏标准的智能电网的安全评估，我们提出了一个数字双胞胎为基础的方法，智能电网的完整生命周期，准确地模拟物理网格的功能，并避免在实际电网上运行的安全测试所造成的服务中断。基于数字孪生的方法有望为智能电网连续和全面渗透测试的标准化模型的开发提供共同基础。
The exponential growth of the Internet of Things in recent years has created an ever larger cyber attack surface, introducing new security vulnerabilities for all computerized systems. Among the most significant of those systems are industrial control systems (ICS) consisting of many cyber physical components, and smart grids are a prominent example of ICS, whose failures have potential to cause major disruptions in all aspects of our daily lives. In this paper, we provide an overview of smart grid cybersecurity standards, and review major threats to smart grid environments at the physical, network and application layers. In order to overcome the current lack of standards for security evaluation of smart grids, we propose a digital twins based approach for the complete life cycle of a smart grid, which accurately models the functioning of the physical grid and avoids service disruptions caused by running security tests on the actual grid. A digital twins based approach is promising to provide a common ground for the development of standardized models for continuous and comprehensive penetration testing of smart grids.
