Impact of grid disturbances on the output of grid connected solar photovoltaic system

The installed power capacity of grid-connected photovoltaic (PV) systems has increased exponentially around the world. The size of each unit is also increasing as they are becoming more affordable. The grid is a highly non-linear system. Hence, the grid disturbances affect the output of the solar PV systems. This paper presents a study of the effects of grid disturbances such as switching of loads, feeder tripping, outage, and synchronization of conventional generators on the output parameters of the grid-connected solar PV system. The voltage, current and power of solar PV at the point of common coupling have been analyzed. Further, the variations of dc output voltage of the solar modules have also been investigated. The results are validated using a 100 kW solar PV system integrated with a test system in MATLAB/Simulink environment. The presence of disturbances is validated using the discrete wavelet transform (DWT).
