论文摘要
现代智能电网提供了几种类型的数字控制和对电力传输和分配的监视，与传统电网相比，可以提高效率和整合功能。但是，这些好处引入了更大的复杂性，并大大破坏并扩大了威胁格局。随着网格连接的设备的增殖，漏洞的数量正在增加。这些脆弱性的社会的潜在成本很难确定，他们成功剥削的可能性也很难确定。在本文中，我们提出了一种比较与智能网格相关的各种网络功能的净经济利益和成本的方法，从网络攻击脆弱性的角度并捍卫它们。网络防御支出的经济考虑表明，在数字功能之间可能存在最佳支出水平。我们说明了关于如何评估数字功能和对捍卫网络攻击的成本进行比较的假设案例研究。
Modern smart grids offer several types of digital control and monitoring of electric power transmission and distribution that enable greater efficiency and integrative functionality than traditional power grids. These benefits, however, introduce greater complexity and greatly disrupt and expand the threat landscape. The number of vulnerabilities is increasing as grid-connected devices proliferate. The potential costs to society of these vulnerabilities are difficult to determine, as are their likelihoods of successful exploitation. In this article, we present a method for comparing the net economic benefits and costs of the various cyber-functionalities associated with smart grids from the perspective of cyberattack vulnerabilities and defending against them. The economic considerations of cyber defense spending suggest the existence of optimal levels of expenditures, which might vary among digital functionalities. We illustrate hypothetical case studies on how digital functionalities can be assessed and compared with respect to the costs of defending them from cyberattacks.
