In recent years, distribution network-connected single-phase and three-phase solar power plants have been growingly used in order to increase network sustainability, reduce loss, and improve voltage profile. Merging renewable distributed generation sources (DG) in distribution networks has caused some problems in measurement of power quality parameters. The use of electronic power devices in photovoltaic...
The LED lamps require a DC current for proper functioning, thus, in order to supply this current, the diode bridge rectifiers in the internal circuit of these lamps are used. One of the problems in the old generation LEDs was the low power factor in these lamps. After development of electronic devices with soft switching, a new generation of LED lamps with high power factor has come into the commercial...
Power distribution system reconfiguration can be achieved by changing the status of sectionalizing and ties switches on the feeders to power loss reduction and voltage profile improvement. The load value in distribution networks depends on hours of day and load type as industrial, commercial, and residential. Nowadays the presence of distributed generation (DG) units in distribution networks increasing...
Distribution network's high resistance and current results in high distribution losses, contributing to large voltage drops, low voltage stability, increased power losses and decreased reliability to sustain disturbance. As the distribution systems generally have composed of industrial, commercial, residential and lighting loads and the peak load on the substation transformers and feeders occur at...
In the past decade, the use of wind turbines connected to distribution networks, in order to improve voltage profile, reduce losses and increase reliability and network security have been increasing. Meanwhile, the role of static converters and power electronic devices in connecting and controlling the wind turbine power is important. In order to generate the maximum power, decrease the mechanical...
In recent years, the use of LED street lights instead of sodium and mercury vapor lights is increased in the distribution networks. The high efficiency and reliability, long life, non-emission of infrared and ultraviolet beams, functioning at very low AC and DC voltage, low heat generation, the application at temperatures from +85 to −40 degrees, are the advantages of these lights. The power electronic...
