  • A. Lewicki
  • Z. Krzemiński

  - Rok 2015

  In this paper the control system of Power Electronic Transformer (PET) for the Smart Grid application is proposed. The structure of PET is based on two Cascaded H-bridge (CHB) converters. The electrical energy is transferred between converters using Dual-Active-Bridges (DAB) and high-frequency transformers. This type of coupling has been used to connect the DC-links of all H-bridges. The proposed control system for PET makes it...

• The Impact of Micro-Sources on Voltage Distortions in a Power Grid

  Publikacja

  • M. Grzymkowska
  • J. Klucznik

  - Acta Energetica - Rok 2020

  The increase in the number of photovoltaic (PV) systems integrated with low voltage (LV) grids has led to a great need to analyse the impact of these systems on the quality of electricity and the reliability of its supply. This paper presents and compares the energy quality requirements imposed by various countries on photovoltaic plants. Then, based on real object tests and simulation in DIgSILENT PowerFactory, the impact has...

• Activity coordination of capacitor banks and power transformer controllers in order to reduce power losses in the MV grid

  Publikacja

  • A. Szultka
  • R. Małkowski

  - Rok 2016

  One of the main issues related to the optimization of the MV (middle voltage) network is to reduce losses of active and reactive power. Lower losses of active and reactive power give not only economic advantage, but also improvement of energy quality. The object of regulation that can be used for these purposes are transformer with On-Load Tap Changer and capacitor's banks. This paper presents results of analysis of the possibility...

• Comprehensive compensation of grid current distortion by shunt active power filters

  Publikacja

  • A. Cichowski
  • W. Śleszyński
  • J. Nieznański

  - Rok 2015

  The paper presents a comprehensive approach to the compensation of grid current distortion in shunt active power filter systems. Four sources of current distortion are addressed: imperfect grid synchronization caused by the distortion in the grid voltages, time delays in the evaluation of grid voltages and computation of compensating currents, fluctuations of the dc bus voltage, and the distortion of inverter output voltages due...

• Single-phase power electronics transformer with active functions for smart grid

  Publikacja

  • V. Minambres-Marcos
  • I. Roasto
  • E. Romero-Cadaval
  • R. Strzelecki
  • F. Barrero-Gonzalez

  - Rok 2015

  This paper presents the control of one cell of a modular single-phase power electronics transformer with active functions for meeting the smart grid concept. In this way, the converter could be used not only as a conventional transformer but also for grid such as reactive power, harmonic elimination and energy storage. The topology of the cell is composed by a bidirectional converter with three stages: a half bridge in the input...

• SMART GRID TECHNOLOGIES IN ELECTRIC POWER SUPPLY SYSTEMS OF PUBLIC TRANSPORT

  Publikacja

  • M. Bartłomiejczyk

  - Transport - Rok 2018

  Nowadays the issue of electric energy saving in public transport is becoming a key area of interest which is connected both with a growth in environmental awareness of the society and an increase in the prices of fuel and electricity. It can be achieved by improving the usage of regenerative breaking. In 2016 the Przedsiębiorstwo Komunikacji Trolejbusowej (PKT, Trolleybus Transport Company) in Gdynia began practical implementation...
