Attack-Resilient Optimal PMU Placement via Reinforcement Learning Guided Tree Search in Smart Grids
IEEE Transactions on Information Forensics and Security, 2022The operation of smart grids heavily relies on secure and accurate meter measurements provided by phasor measurement units (PMUs). Therefore, the optimal PMU placement (OPP) aiming to achieve the complete system observability of smart grids with as few ...

PMU Location Determination in a Hybrid PMU-SCADA System
2020 12th International Conference on Information Technology and Electrical Engineering (ICITEE), 2020The accurate real-time state estimation is needed to perform real-time monitoring and control. However, the current power system uses SCADA technology as a tool for monitoring and control. SCADA existing measurement device has a few disadvantages: low accuracy, low sampling rate in measuring the measurements data, and asynchronous measurements between ...

2020 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2020
In this paper, we map the PMU data to a graph via the visibility algorithm to generate the PMU visibility graph. Applying complex network analysis to this graph unravels several hidden features in the PMU data. The applications of the PMU visibility graphs in the real power grid include anomaly detection, topology identification, and state estimation ...

A Security Mechanism for IEEE C37.118.2 PMU Communication
IEEE transactions on industrial electronics (1982. Print), 2022Phasor measurement units (PMUs) are widely used to monitor the operating conditions of a smart grid. The PMU communication network is, generally, a public wide area network, hence it is vulnerable to cyberattacks.

Accurate phase calibration of PMUs and PMU calibrators
2016 Conference on Precision Electromagnetic Measurements (CPEM 2016), 2016A measurement setup is developed for accurate phase calibration of phasor measurement units (PMUs) and PMU calibrators. The measurement method is based on generating a reference signal with known phase with respect to a 1 pulse-per-second time reference using a stepped sine wave signal.

2023 IEEE 13th International Workshop on Applied Measurements for Power Systems (AMPS), 2023
The Phasor Measurement Unit (PMU) is perhaps the first representational measurement widely dispersed in the electric power system. Its usefulness has been demonstrated on many occasions. It is shown in this paper that the excellent performance of the PMU is a tribute to PMU makers, and not attributable to the standards that are supposed to specify the ...

PMU-Based System State Estimation for Multigrounded Distribution Systems
IEEE Transactions on Power Systems, 2021Linear network modeling and phasor measurement units (PMUs) simplify the traditional system state estimation (SSE) problem. The existing multiphase SSE-PMU-based models are linear including earthing resistances as a fixed and invariable parameter ...
