Sensitivity Analysis of Medium Frequency Transformer Design

Drazen Dujic, Marko Mogorovic

This paper discusses the technical challenges and trade-offs tied to design of medium frequency transformers (MFTs) for medium-voltage (MV) high-power (HP) power electronic applications, namely emerging solid state transformers (SSTs). A detailed analysis ...

Transient Impedance of Interconnected Wind Turbine Grounding Systems

Marcos Rubinstein, Antonio Sunjerga, Farhad Rachidi-Haeri, Qi Li

Wind turbines are very vulnerable to lightning because of their height, sharp edges and remote locations often with low soil conductivity. In this paper we present numerical simulations of the impedance of a typical wind turbine grounding geometry. We anal ...

Vacuum circuit breaker modelling for the assessment of transient recovery voltages: Application to various network configurations

Mario Paolone, Carlo Alberto Nucci

Vacuum circuit breakers (VCBs) are widely used for medium voltage applications when low maintenance, long operating life, and large number of allowable switching cycles are required. The accurate estimation of the transient recovery voltages (TRVs) associa ...

Control of Battery Storage Systems for the Simultaneous Provision of Multiple Services

Mario Paolone, Emil Namor, Fabrizio Sossan

In this paper, we propose a control framework for a battery energy storage system to provide simultaneously multiple services to the electrical grid. The objective is to maximise the battery exploitation from these services in the presence of uncertainty ( ...
