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 ...

On the integration of low frequency transformer into modular multilevel converter

Drazen Dujic, Alexandre François Christe

Various high power applications require power converters with large voltage step ratios, easily achieved by inclusion of a single or multiple transformers, which provide galvanic isolation at the same time. This paper presents, in a systematic manner, the ...

State-space modeling of modular multilevel converters including line frequency transformer

Drazen Dujic, Alexandre François Christe

This paper presents a detailed state-space modeling of a Modular Multilevel Converter (MMC) in combination with line frequency transformer (LFT). The classical MMC topology is compared with the recently proposed Open-End Winding MMC (OEWMMC) topology, whic ...

Efficient Computation of Sensitivity Coefficients of Node Voltages and Line Currents in Unbalanced Electrical Networks

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

The problem of optimal control of power distribution systems is becoming increasingly compelling due to the progressive penetration of distributed energy resources in this specific layer of the electrical infrastructure. Distribution systems are, indeed, e ...

Power and DC Link Voltage Control Considerations for Indirect AC/AC Modular Multilevel Converters

Alfred Rufer, Michail Vasiladiotis, Stephan Kenzelmann, Nicolas Cherix

A highly interesting application field of the Modular Multilevel Converter is the interconnection of the European three-phase 50 Hz industrial grid with the single-phase 16 2/3 Hz railway supply. Contrary to existing technologies, the utilization of a bulk ...

Power Network Disturbances due to the Presence of FACTS

Michel Ianoz

The necessity to take into account environment problems and in parallel a need for more energy, for the development of emerging economies, makes the management of energy sources a very important problem. The electric transmission network is charged with mo ...

Computations of AC loss in the ITER magnets, during fast field transients

Pierluigi Bruzzone, Jonathan Bryan Lister, Luca Bottura

The calculation of AC loss due to the control currents in ITER is a cumbersome task. The reason is that control transients require small field changes (0.1 T or less) at moderate frequency (up to 10 Hz), where effects of partial penetration of the filament ...
