Decomposition of power system state estimation problem as a method to tackle cyber attacks

... attacks (CA) on data collection and processing systems. The paper presents a new decomposition approach to solve the SE problem under cyber attack: the calculation network is divided into areas that have a SCADA server and a Wide Area Measurement System (WAMS) concentrator at the center of every area. To detect the CA event and its localization, we propose to use a combination of a-priori and a-posteriori bad data detection (BDD). © 2018 IEEE. нет

A fault tree cyber security analysis of power system state estimation software

... (print): 9788055331959. The paper is concerned with the material devoted to the problem of resistance of the state estiamtion (SE) procedure to cyberattacks on the system for collection and processing of PMU measurements, i.e. wide area monitoring system (WAMS), and the SE procedure itself. Based on the analysis of potential cyberattacks, which reveals the most vulnerable WAMS components, we show the conditions for a failure of the SE procedure. The method of fault tree is proposed to describe the consequences ...
