Experimental Implementation of Frequency Regulation Service Using Commercial Buildings

Colin Neil Jones, Ioannis Lymperopoulos, Tomasz Tadeusz Gorecki, Faran Ahmed Qureshi, Luca Fabietti, Altug Bitlislioglu

Frequency control reserves are a fundamental mechanism in the current electric power system to preserve the balance between demand and generation of active power at all times. The traditional approach is to exploit conventional power plants for frequency r ...

20-300 MHz Frequency Generator with-70 dBc Reference Spur for Low Jitter Serial Applications

Catherine Dehollain, Gürkan Yilmaz

This paper presents a frequency synthesizer based on a phase locked loop (PLL) targeting low jitter applications. The frequency generator covers a range wider than a decade, more explicitly from 20 to 300 MHz. Thanks to a 4-stage ring oscillator, it can pr ...

Analysis of Dielectric Microbead Detection by Impedance Spectroscopy with Nanoribbons

Carlotta Guiducci, Enrico Accastelli, Paolo Scarbolo, Luca Selmi, Thomas Ernst

We present a quantitative numerical analysis of dielectric microbead detection experiments with nanoribbons operated in the AC small signal regime. To this purpose, a comprehensive model of nanoribbon operation in electrolyte environment and with DC/AC sig ...

Voltage Stability Analysis using a Complete Model of Grid-Connected Voltage-Source Converters

Mario Paolone, Andreas Martin Kettner

Due to the increasing popularity of renewable energies, a significant share of the power generation in future microgrids is expected to originate from converter-interfaced Distributed Energy Resources (DERs). Traditionally, idealized device models are used ...

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 ...

Generalized impedance boundary conditions for strongly absorbing obstacle: The full wave equation

Hoài-Minh Nguyên

This paper is devoted to the study of the generalized impedance boundary conditions (GIBCs) for a strongly absorbing obstacle in the time regime in two and three dimensions. The GIBCs in the time domain are heuristically derived from the corresponding cond ...

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 ...
