This paper is concerned with the power system state estimation (PSSE) problem, which aims to find the unknown operating point of a power network based on a given set of measurements. The measurements of the PSSE problem are allowed to take any arbitrary combination of nodal active powers, nodal reactive powers, nodal voltage magnitudes and line flows. This problem is non-convex and NP-hard in the...
Jamming refers to the deletion, corruption or damage of meter measurements that prevents their further usage. This is distinct from adversarial data injection that changes meter readings while preserving their utility in state estimation. This paper presents a generalized attack regime that uses jamming of secure and insecure measurements to greatly expand the scope of common 'hidden' and 'detectable'...
Unobservable data integrity attacks are coordinated cyber attacks on power meter readings that are undetectable by any bad data detection algorithm. Counter measures against data integrity attacks have been extensively studied in the context of observable islands; however, the concept of observable islands has only been introduced for a specific type of attack known as the power injection attack which...
Undetectable data attacks on the power grid produces errors in the state estimation that can potentially affect electricity prices as well as make the grid vulnerable to failures. A new hidden attack framework is presented for power grids where all meter measurements are secure from injection of malicious data. An adversary here only jams or blocks meter data from being sent to the control center...
In this panel session paper, we discuss the interaction of market power in electricity markets, market power mitigation procedures in place in various independent system operators in North America, particularly in the context of transmission constraints, and the efficiency of the markets.
