Inertia location and slow network modes determine disturbance propagation in large-scale power grids

Philippe René Joseph Jacquod

Conventional generators in power grids are steadily substituted with new renewable sources of electric power. The latter are connected to the grid via inverters and as such have little, if any rotational inertia. The resulting reduction of total inertia ra ...

Harmonic Phasor Measurements in Real-World PMU-Based Acquisitions

Mario Paolone, Asja Derviskadic, Guglielmo Frigo

Modern distribution networks prove to be easily prone to power quality issues, and in particular to the presence of harmonic. components in the voltage and current signals, due to the increasing presence of nonlinear loads, distributed generation, and rene ...

Concurrent Voltage Control and Dispatch of Active Distribution Networks by means of Smart Transformer and Storage

Mario Paolone, Fabrizio Sossan, Konstantina Christakou, Xiang Gao

Dispatching active distribution networks is expected to play an important role in the smart grid technologies. Voltage control is also starting to be widely proposed to avoid voltage violations in the electrical grid. The integration of the storage in the ...

Galvanically Isolated Modular Converter

Alexandre François Christe

The ever increasing penetration of renewable energy systems in the distribution grids will inevitably require profound changes in the grid infrastructure. One emerging direction, the medium voltage dc (MVdc) grids, is the cornerstone of this work. They are ...

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, Chang Ge

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 ...
