最近在配电系统中增加的信息和通信技术引入了一类新的电力盗窃或非技术性损失。能源消耗数据可以通过网络攻击隐藏和更改，其特征是未经授权访问应用程序数据库和智能电表的数字篡改。为解决这些类型的非技术性损失而开发的具有成本效益的算法也旨在减少商业损失，因为对信息系统的全面保护是非常昂贵的。因此，本文提出了一种策略来检测非技术性损失，使用多变量控制图，建立一个可靠的区域监测测量的方差。在检测到非技术损失后，基于A-Star算法的寻路过程能够定位具有非技术损失的消耗点。此外，地理信息系统应用程序显示作为网络攻击目标的消费点。数值结果表明，所提出的方法适用于监测一个真实的配电网的选择性和效率。
The recent addition of information and communication technologies in electric power distribution systems has introduced a new class of electricity theft or nontechnical loss. Energy consumption data can be hidden and altered through cyber-attacks that are characterized by the unauthorized access to the application database and digital tampering of smart meters. The development of cost-efficient algorithms to address these types of nontechnical losses also targets the reduction of commercial losses because the full protection of an information system is very expensive. Thus, this paper proposes a strategy to detect nontechnical losses using a multivariate control chart that establishes a reliable region for monitoring the measured variance. After the detection of nontechnical losses, a pathfinding procedure based on the A-Star algorithm is able to locate the consumption point with the non-technical loss. Moreover, a geographical information system application displays the consumption point that is the target of the cyber-attack. The numerical results demonstrate the selectivity and efficiency of the proposed methodology applied for monitoring a real distribution network.
