Experimental study on flicker emissions by photovoltaic systems

A 1.84 kW photovoltaic system is connected to phase A of the distribution network. A 15 kW generator is used to be the supply source to the network because the generator does not generate any severe flickers to the network. As a result, any flickers experienced at the point of the common coupling are generated from the photovoltaic
