Impact of Grid Connected Photovoltaic System on Total Harmonics Distortion THD

Integrating renewable energy resources, especially photovoltaic systems with microgrids have become an unavoidable choice for most countries and India has achieved its NDC target with a total non fossil based installed energy capacity of 157.32 GW which is 40.1 of the total installed electricity capacity. As per Foreign Direct Investment FDI data cell, DPIIT, the Indian ”˜Non Conventional Energy' sector received an FDI of US 797.21 million during 2020 21. On 28.04.2021, the Government introduced, Production Linked Incentive Scheme “National Programmed on High Efficiency Solar PV Modules” with an outlay of Rs. 4,500 crores to support and promote the manufacturing of high efficiency solar PV modules. Which in turn bring some challenge to the electrical utility operator. The results are demonstrated by determining the THD versus the photovoltaic load flow to the connected grid. Moreover, two solutions for power quality improvement are suggested. The first is based on switching at very low current flow conditions and the second is based on adding filters to the system. Finally, the two proposed approaches are implemented using MATLAB Simulink simulation and are compared for their efficiency and applicability.
