The smart grid is characterized by the proliferation of advanced digital controllers at all levels of its operational hierarchy from generation to end consumption. Such controllers within modern residential and commercial buildings enable grid operators to exercise fine-grained control over energy consumption through several emerging buildings-to-grid (B2G) applications. Though this capability promises...
In the power grid, Supervisory Control and Data Acquisition (SCADA) systems are used for executing various applications for monitoring and controlling purposes, which in turn enable stable operation of the grid. The integrity and timely delivery of SCADA data is critical to the operation of the grid and this makes them an attractive target for cyber-attacks. However, SCADA systems have various vulnerabilities...
The electrical grid is one of the critical infrastructures of any country whose importance makes them an attractive target for malicious cyber attacks. This paper considers the particular case of data modification attacks in smart grids, where the data generated by Phasor Measurement Units (PMUs) is modified by the adversary in order to introduce errors in the monitoring and control applications that...
The importance of phasor measurement unit (PMU) or synchrophasor data towards the functioning of real-time monitoring and control of power generation and distribution systems makes them an attractive target for cyber-attacks. An attack with potential for significant damage is the packet drop attack, where the adversary arbitrarily drops packets with synchrophasor data. This paper develops a real-time...
The fundamental role of the measurement and control information in the normal operation of smart grids makes cyber-security a critical necessity for existing and future power systems. This paper addresses the problem of detecting data manipulation attacks on smart grids, in the particular context of the data from Phasor Measurement Units (PMUs). The proposed methodology is based on comparing the estimates...
The use of synchrophasor data for observation and control is expected to enhance the operation and efficiency of the next generation of power transmission systems. The synchropha-sor measurement data is usually transferred over public domain networks such as the Internet, thereby making it susceptible to a number of attacks. This paper focuses on packet dropping or gray hole attacks on networks carrying...
