Voltage Flicker and Variation in Distributed Photovoltaic Grid Transformers
IEEE Standard 519 clearly states the requirements for harmonic control in transformers connected to grids which may contribute to the quality of the signal. This is connected to several nth harmonics that may cause a change in the nominal value of the voltage at the terminals of the distributed photovoltaic grid transformer (DPV-GT). Besides, the load connected at the grid on the AC end may cause a nonuniform time requirement as in the case of battery charging scheduled by customers for their electrical vehicles.
Generally in a traditional solar power system, voltage is generated at a low voltage (28 volts DC) and transmitted by a step-up transformer at a higher ...
