Reactive power control of three-phase low voltage system based on voltage to increase PV penetration levels

High penetration levels of distributed (PV) generation on electrical distribution system show many opportunities and challenges for Egyptian Distribution Utilities. The sovereign purposiveness of this threshing was to augment the penetration level of the PV power production in three-phase LV grids, by using solar inverters with reactive power control inconvertibility, imposed by certain grid codes. This method, which is based on the grid voltage profile for location - dependent PF set premium could be cushioned to whole solar inverter. The main target was to mitigate unnecessary Q absorption. This method combines two droop function power factor active power and Q-(V) strategies. The performance of each inverter is to compare the output voltage measured and control the quantity of Q. Therefore, improvement of the voltage profile at a certain bus can reduce the total losses, saving consumed power by customer and increase the system capacity by 4.5%. (C) 2017 Ain Shams University.
