Survey on synchrophasor data quality and cybersecurity challenges, and evaluation of their interdependencies

Abstract

Synchrophasor devices guarantee situation awareness for real-time monitoring and operational visibility of the smart grid. With their widespread implementation, significant challenges have emerged, especially in communication, data quality and cybersecurity. The existing literature treats these challenges as separate problems, when in reality, they have a complex interplay. This paper conducts a comprehensive review of quality and cybersecurity challenges for synchrophasors, and identifies the interdependencies between them. It also summarizes different methods used to evaluate the dependency and surveys how quality checking methods can be used to detect potential cyberattacks. In doing so, this paper serves as a starting point for researchers entering the fields of synchrophasor data analytics and security.

Analysis of Cyber Attacks Against Micro-PMUs: The Case of Event Source Location Identification

“…In fact, the majority of the studies in this field PMU cyber-security focus on traditional PMUs at transmission level. A general survey of cyber-security challenges in PMUs is presented in [4]. In [5], a method is proposed to detect anomalies in PMU data by continuously monitoring the equivalent impedances of transmission lines obtained from PMU measurements.…”

Latency-Optimal Network Intelligence Services in SDN/NFV-Based Energy Internet Cyberinfrastructure

“…The NASPInet has contextualized five classes of data services for synchrophasor applications with specific traffic attributes. As depicted in Table 1 [32], class A is to support the needs of high-performance feedback control applications. Thus, the reliable cyberinfrastructure for this class is critically essential.…”

Analytical and stochastic method in order to build safety and security block diagrams of cyber assets of SCADA system for critical infrastructure

“…Не зважаючи на відповідність певним нормативним вимогам, нині відомі факти та наслідки хакерських атак на кіберактиви національної КІ [1], що підтверджують її вразливість. Цей негативний фактор впливу, який створено ненавмисно штучно, відображає кіберфізичну природу КІ [26] та відкриває різноманітні можливості щодо втручання в контур управління інфраструктури завдяки використанню активів системи SCADA. Відповідно до [27], серйозною загрозою для систем SCADA можуть бути вразливості їхнього програмного забезпечення, які створюють передумови для успішної реалізації кібератак різноманітного походження.…”
