Designing a Passive Filter for Reducing Harmonic Distortion in the Hybrid Micro-grid Including Wind Turbine, Solar Cell and Nonlinear Load
Published by Ali BAGHERI, Mohsen ALIZADEH, Department of Electrical Engineering, Yadegar -e- Imam Khomeini (RAH) Shahre Rey Branch, Islamic Azad University, Tehran, Iran Abstract. One of the most important indices of power quality in distribution grids is the harmonic distortion, which can affect the reliability of the micro-grid. On the other hand, the growth ofContinue reading “Designing a Passive Filter for Reducing Harmonic Distortion in the Hybrid Micro-grid Including Wind Turbine, Solar Cell and Nonlinear Load”
The Quality of Electric Power Supplied into the Grid by Co-Generation Units
Published by Jiri JANSA, Petr MOLDRIK, Daniel MINARIK, VSB – Technical University of Ostrava Abstract. This paper deals with the utilisation of firedamp for combined heat and electric power generation. The firedamp is gained from hard-coal mines and can be combusted in a co-generation units with gas-engine. This process involves more efficient utilisation of firedamp.Continue reading “The Quality of Electric Power Supplied into the Grid by Co-Generation Units”
