Cyber-attacks against power systems have been widely researched in recent years. Several studies have so far focused on ways of deceiving the state estimator so that the resulting estimates would be wrong. On the other hand, the role of network topology and measurement design on detectability of cyber-attacks has not been widely investigated. This work examines the measurements and network topology to identify vulnerabilities against targeted cyber-attacks. Specifically, it considers the leverage measurements, whose errors are typically not easily detected and therefore they may bias estimators when they carry gross errors. The paper also illustrates that this vulnerability can be addressed by strategic replacement of few of these measurements by phasor measurement units (PMUs).

Identifying vulnerabilities of state estimators against cyber-attacks Göl, Murat (null; 2013-11-04) State estimation has an important role in the operation of power systems and associated power markets. It is well known that state estimators are vulnerable to any existing critical measurements since their errors cannot be detected. Therefore, by manipulating a finite number of critical measurements, a hacker can bias the results of state estimation without being detected. Those biased results include both system states (bus voltage magnitudes and angles) and branch flows that are calculated by using the s...
Rapid tracking of bus voltages using synchro phasor assisted state estimator Göl, Murat; Floyd, Galvan (2012-10-10) State estimation has a key role in secure operation of power systems and management of power markets. It calculates the optimal estimates of the system states using the available measurements. Increasing number of phasor measurement units (PMU) installed in power systems motivated their integration also into state estimators which so far relied solely on SCADA measurements. However, different refresh rates of PMU and SCADA measurements present a challenge in their efficient integration. This paper proposes ...
Modeling and investigation of fault ride through capability of variable speed wind turbines Koç, Erkan; Güven, Ali Nezih; Department of Electrical and Electronics Engineering (2010) Technological improvements on wind energy systems with governmental supports have increased the penetration level of wind power into the grid in recent years. The high level of penetration forces the wind turbines stay connected to the grid during the disturbances in order to enhance system stability. Moreover, power system operators must revise their grid codes in parallel with these developments. This work is devoted to the modeling of variable speed wind turbines and the investigation of fault ride troug...
Optimal mix of a solar, wind, and fuel cell hybrid residential system Chehab, Khalil; Fahrioğlu, Murat; Sustainable Environment and Energy Systems (2018-1) Nowadays, supplying electrical power using renewable energy systems faces problems due to the high cost and unreliability of those systems. With the variability of renewable energy sources, a possible way to provide electricity is by combining different renewable sources in one hybridized system. This study is about optimizing and testing the feasibility of different hybridized systems including solar, wind, and fuel cell systems. The study will include on-grid and off-grid optimal solutions for a case stud...
Strategic Cyber-Security Perspective in Smart Grids Canbek, Gurol; SAĞIROĞLU, Şeref (2018-03-25) Conventional energy grids growing in time have become complex, inefficient and expensive to operate and use. They are critical because of providing the whole energy needs of the technologies required for our modern life but also cumbersome entities. "Smarting" the grids by automating, facilitating the troubleshooting and productivity analysis with the help of information technologies infrastructure, reinforcing the controls, charging the services in details makes it possible to administrate efficiently and ...
