Design and Experimental Validation of an LTE-Based Synchrophasor Network in a Medium Voltage Distribution Grid

Mario Paolone, Asja Derviskadic, Paolo Romano, Marco Pignati, Lorenzo Zanni

We present and experimentally validate in a real-scale medium voltage (MV) grid a synchrophasor network that exploits the availability of a public 4G LTE communication infrastructure. An 18 buses, 10 kV feeder located in Huissen, The Netherlands, has been ...

Experimental Validation of a Steady State Model Synthesis Method for a Three-Phase Unbalanced Active Distribution Network Feeder

Mario Paolone, Fabrizio Sossan, Marco Pignati, Farhan Mahmood

This paper presents the field validation of a method that performs steady-state model synthesis (SSMS) of active distribution networks using syncrophasor measurements. The validation is performed by applying the SSMS method on a real active distribution fe ...

Undetectable Timing-Attack on Linear State-Estimation by Using Rank-1 Approximation

Jean-Yves Le Boudec, Mario Paolone, Marco Pignati, Sergio Barreto Andrade, Gyorgy Miklos Dan

Smart-grid applications based on synchrophasor measurements have recently been shown to be vulnerable to timing attacks. A fundamental question is whether timing attacks could remain undetected by bad-data detection algorithms used in conjunction with stat ...

Architecture and Experimental Validation of a Low-Latency Phasor Data Concentrator

Mario Paolone, Asja Derviskadic, Paolo Romano, Marco Pignati

The paper presents the design principles of a Phasor Data Concentrator (PDC) that implements both the absolute and relative time data pushing logics together with a third one that aims at minimizing the latency introduced by the PDC without increasing the ...

Fault Detection and Faulted Line Identification in Active Distribution Networks Using Synchrophasors-based Real-Time State Estimation

Mario Paolone, Paolo Romano, Marco Pignati, Lorenzo Zanni, Sidi-Rachid Cherkaoui

We intend to prove that PMU-based state estimation processes for active distribution networks exhibit unique time determinism and refresh rate that make them suitable to satisfy the time-critical requirements of protections as well as the accuracy requirem ...

Definition of Accurate Reference Synchrophasors for Static and Dynamic Characterization of PMUs

Mario Paolone, Asja Derviskadic, Guglielmo Frigo, Marco Pignati, Daniele Colangelo

The calibration of phasor measurement units (PMUs) consists of comparing coordinated universal time time-aligned phasors (synchrophasors) measured by the PMU under test, against reference synchrophasors generated through a PMU calibrator. The IEEE Standard ...
