Graphical Abstract:


Background: A distribution system which supplies clean power to the users is the requirement of the modern time. Solar PVs are integrated with the power electronics interface in the conventional system to cater the load demand.

Methods: This arrangement injects harmonics in the system. Furthermore, the diverse nature of the consumer load injects potential harmonics in the system. The harmonic polluted such system produces the harmful effect on the connected equipment. To minimize the impact of harmonics and improve the distribution grid performance, passive filters are obvious choice due to their portable and low cost solution. This paper presents the planning and performance evaluation of C-type passive filters for a solar PV integrated distribution system. The goal of this paper is to plan and evaluate the performance of passive filter from various aspects to check its suitability for solar PV integrated distribution system.

Results: This paper presents the results on the effectiveness of C-type filter for minimizing harmonic distortions and resonance in distribution grid.

Conclusion: Our findings show that the C-type filter effectively mitigate the potential harmonics and alleviate the harmonic resonance problem, thereby improving the power quality and protective system performance.

Keywords: C-type passive filter, grid integrated solar photovoltaic(PV), harmonics, harmonic resonance, power flow, total harmonic distortion (THD).
