  • G. Kumar
  • G. Piechota

  - RENEWABLE ENERGY - Rok 2023

  The topics addressed in the article concern the problem of exploiting the potential of renewable energy sources (RES) at the regional level and the problem of the course of regional energy transition processes. Throughout the world, energy transition proceeds in a specific way for each country, due to the different potential of the selected RES and political, institutional and socio-economic conditions. Energy transition processes...

  • W. Pawlicki
  • A. Lenarczyk

  - Rok 2018

  The intermittency of renewable energy sources (RES) constitutes a challenge for effective power system control. Fossil-fuel-based units offering ancillary power services to meet the short-term power imbalance are a financial and environmental burden for the society. Energy storage systems (ESS) can be the solution in view of the electricity market development and growing environmental concern. The major questions are, in what circumstances...

• Stirling engines powered by renewable energy sources

  Publikacja

  • J. Kropiwnicki

  - Rok 2015

  Stirling engine is a device that produces mechanical energy using heat from any source of energy, without the need of combustion of any fuel inside the device. Renewable energy sources, which are mostly low-temperature energy sources, can be used to produce mechanical and electrical energy in Stirling engines. The paper presents an overview of the existing prototype Stirling engines designed for using of low-temperature energy...

• Voltage control in a power system with renewable sources of energy

  Publikacja

  • B. Tarakan
  • S. Czapp
  • K. Dobrzyński
  • R. Zajczyk
  • M. Sarnicki

  - Rok 2019

  Intensive development of distributed generation in power systems, caused by the European Union energy policy, gives possibility for improving safety in power delivery as well as optimizing the costs of the systems functioning. In this context, distributed generation can be used for voltage control in power systems – it can be performed by the control of reactive power of each source of energy or a group of energy sources. This...

• Residual current devices in installations with PV energy sources

  Publikacja

  • S. Czapp

  - Przegląd Elektrotechniczny - Rok 2022

  The paper presents the principles of residual current devices (RCDs) application in photovoltaic (PV) installations. Provisions of standards in this regard are commented on, in particular, attention is drawn to the lack of obligation to use of RCDs in PV installations. The issue of the shape of the earth fault current and the level of leakage currents in such installations are discussed. These factors influence the selection of...
