How Smart is the Grid?
François Maréchal, Luc Girardin, Ermanno Lo Cascio, Zhichuan Ma
Ancient Romans called urbs the set of buildings and infrastructures, and civitas the Roman citizens. Today instead, while the society is surfing the digital tsunami, urbs and civitas tend to become much closer, almost merging, that we might attempt to cond ...
2021MMC-based conversion for MVDC applications
In recent years, DC grids have gained momentum due to the advantages they display over their AC counterparts. For instance, high voltage DC grids have been established as the most prominent solution in the underwater power transmission or interconnection o ...
EPFL2020Real-Time Control of an Electric Vehicle Charging Station While Tracking an Aggregated Power Setpoint
Jean-Yves Le Boudec, Mario Paolone, Lorenzo Enrique Reyes Chamorro, Cong Wang, Roman Rudnik, Jagdish Prasad Achara
We consider the problem of controlling the charging of electric vehicles (EVs) connected to a single charging station that follows an aggregated power setpoint from a main controller of the local distribution grid. To cope with volatile resources such as l ...
2020Optimal path to a high share of distributed PV in low-voltage distribution grids
To limit global warming, the energy transition from fossil fuels to renewables is one of the main challenges of this century. This transition will help decrease our CO2 emissions, create jobs, contribute to a broader revenues distribution, improve energy s ...
EPFL2020Performance Comparative Assessment of Grid Connected Power Converters Control Strategies
Mario Paolone, Giacomo Piero Schiapparelli
Renewable energy sources are generally interfaced with the electric distribution and transmission grid via power converters. The displacement of the traditional generating plants requires the new resources to be involved in the grid control strategy. This ...
IEEE2020Hierarchical Control in Islanded DC Microgrids With Flexible Structures
Giancarlo Ferrari Trecate, Pulkit Nahata, Alessio La Bella
Hierarchical architectures stacking primary, secondary, and tertiary layers are widely employed for the operation and control of islanded dc microgrids (dcmGs) composed of distribution generation units (DGUs), loads, and power lines. However, a comprehensi ...
2020Thermal Study of a Modular Multilevel Converter Submodule
Drazen Dujic, Ignacio Alejandro Polanco Lobos
Modular multilevel converters are gaining attention since medium voltage direct current grids have been proposed as the new key technology for the future transmission and distribution systems. The design of such systems need to address several challenges a ...
2020Real-Time State Estimation and Voltage Stability Assessment of Power Grids: From Theoretical Foundations to Practical Applications
The operators of power distribution systems strive to lower their operational costs and improve the quality of the power service provided to their customers. Furthermore, they are faced with the challenge of accommodating large numbers of Distributed Energ ...
EPFL2019Stability Analysis of Primary Plug-and-Play and Secondary Leader-Based Controllers for DC Microgrid Clusters
Giancarlo Ferrari Trecate, Michele Tucci, Andrea Martinelli, Renke Han
In this paper, we propose a new hierarchical control scheme for microgrid (MG) clusters, given by the interconnection of atomic dc MGs with ZIP loads, each composed by both grid-forming and grid-feeding converters. In the primary level, we develop a new Pl ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2019Multi-Variable High-Frequency Input-Admittance of Grid-Connected Converters: Modeling, Validation and Implications on Stability
Drazen Dujic, Francisco Daniel Freijedo Fernández, Marc Ferrer Duran
Modern grids are facing a massive integration of power electronics devices, usually associated to instability issues. In order to assess the likelihood and severity of harmonic instability in the high frequency region, this work develops a multi-variable i ...
