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 ...

Technologies for Integration of Large-Scale Distributed Generation and Volatile Loads in Distribution Grids

Jean-Yves Le Boudec, Mario Paolone, Jagdish Prasad Achara

As fossil fuel reserves are limited in stock and there is an urgent call to reduce the carbon footprint, distribution grids urgently need to move towards heavy use of local and distributed generation of electricity using renewable energy sources. Another p ...

Voltage Stabilization in MVDC Microgrids Using Passivity-Based Nonlinear Control

Giancarlo Ferrari Trecate, Pulkit Nahata, Andrea Martinelli

This paper investigates the application of passivity-based nonlinear control to the problem of primary voltage stabilization in medium-voltage DC microgrids (MVDC mGs) given by the interconnection of nonlinear distributed generation units (DGUs) and power ...

Optimizing HVDC Grid Expansion and Control for Enhancing DC Stability

Maryam Kamgarpour, Luca Furieri

This paper analyzes the problem of the expansion of an offshore HVDC network. We assess which new HVDC link deployment ensures the highest stabilization of the DC voltage under transient conditions, in the worst-case scenario and for a given grid topology. ...

Unsupervised Disaggregation of PhotoVoltaic Production from Composite Power Flow Measurements of Heterogeneous Prosumers

Mario Paolone, Fabrizio Sossan, Lorenzo Nespoli, Vasco Medici

We consider the problem of estimating the (unobserved) amounts of PV generation and demand in a power distribution network starting from measurements of the aggregated power flow at the point of common coupling (PCC) by leveraging local global horizontal i ...

Full Discrete Modeling, Controller Design, and Sensitivity Analysis for High-Performance Grid-Forming Converters in Islanded Microgrids

Francisco Daniel Freijedo Fernández, Federico De Bosio

Recent works have shown that the state-feedback decoupling of capacitor voltage allows for drastic bandwidth enlarging of current controllers for grid-forming converters in islanded microgrids. Furthermore, Smith predictor and lead compensation have been a ...

Handling Large Power Steps In Real-time Microgrid Control Via Explicit Power Set-points

Jean-Yves Le Boudec, Mario Paolone, Lorenzo Enrique Reyes Chamorro, Andrey Bernstein, Roman Rudnik

We consider a microgrid with real-time control using explicit power-setpoints. Sudden power-steps, such as load disconnections or load in-rushes, directly affect the decisions of the microgrid controller that aims at avoiding voltage or line-ampacity viola ...
