Advanced Droop Control in Islanded Microgrids Using Dynamic Phasor Models

A dynamic phasor model for low- and medium-voltage distribution grids is presented. This model accurately represents the transient dynamics of this type of grid, and its low order makes it well suited for control design. A novel fixed-structure, robust con ...

A Robust Active Damping Control Strategy for an LCL-based Grid-connected DG Unit

Alireza Karimi, Aboutaleb Haddadi

The connection of a DG unit to a weak power system is challenging due to stability issues resulted from dynamic interactions between the DG unit and the grid. LCL-based DG unit is a particularly challenging case due to the presence of a high resonant peak ...

Power-System State Estimation based on PMUs

Lorenzo Zanni

An increasing number of phasor measurement units (PMUs) are being deployed in power systems in order to enhance the situational awareness and, in the near future, we expect that many networks will be extensively equipped with PMUs. These devices provide ac ...

Optimal voltage control processes in active distribution networks

Jean-Yves Le Boudec, Mario Paolone, Dan-Cristian Tomozei, Konstantina Christakou

Typical optimal controls of power systems, such as scheduling of generators, voltage control, losses reduction, have been so far commonly investigated in the domain of high-voltage transmission networks. However, during the past years, the increased connec ...

Static and recursive PMU-based state estimation processes for transmission and distribution power grids

Jean-Yves Le Boudec, Mario Paolone, Lorenzo Zanni, Styliani Sarri

In the operation of power systems, the knowledge of the system state is required by several fundamental functions, such as security assessment, voltage control and stability analysis. By making reference to the static state of the system represented by the ...

Energy and Reserve Management in Interconnected Systems including Electric Railway and Public Power Grids

Mokhtar Bozorg

For historical reasons, the frequency of Electric Railway Power System (ERPS) in central European countries (e.g., Switzerland, Germany and Austria) is different from the frequency of the public power grid. To feed such a low frequency (i.e., 16.7 Hz) syst ...

Optimization-Based Voltage Support in Traction Networks Using Active Line-Side Converters

Alfred Rufer, Behrooz Bahrani

Low system voltage in traction networks, mainly caused by active power absorption of locomotives, adversely affects the performance of the locomotives and also the power transmission capability of the catenary line. This paper introduces a voltage support ...
