Thus, from the literature survey, we can conclude that the solar panel has considerable impact on performance of the distribution transformer, and that further study is needed to find other impacts on the transformer, so that the diagnosis of the transformer can be done at the earlier stage and the transformer saved from any decaying process.
The use of semiconductors, starts from the junction box itself (while, solar cells themselves being semiconductors, in the first place). The junction box is a hermetically sealed box which provides the electrical termination for the solar panel. A solar panel is a series-parallel combination of many solar cells arranged in strings.
It discussed the impact of solar panel on the distribution system and transformer and concluded that as the number of PV panels increases, distortion in voltage and current increases, as does the losses and the temperature. The effect of solar panel on the transformer sizing is obtained by the Freitas et al. ( 2018) in 2015.
Solar photovoltaic power semiconductor-based converters have gradually developed exceedingly effective, lightweight, and durable, permitting maximum power from the sun to be obtained in household, commercial, and industrial applications.
But the harmonics effects caused by the solar panel have negative impact on performance of transformers. Reversal of power is also one of the negative impacts of PV penetration. Furthermore, the frequency of working of OLTC increased by 45% due to solar integration, which may increase the risk of failure of transformers.
The selection of transformer size depends mainly upon the plant peak power, the average power, the amount of generated energy solar irradiation and time diagrams. Transformers are generally designed for a more constant loading operation and might not be designed for daily switching, which may be required in a PV system.
