FFT Analysis of THD in Distribution System with Grid Connected RES

Avinash Kumar Tiwari, A.K.Jhala

To preserve the conventional fuels for the long time and to reduce the other environmental issues it is important to use the non-conventional energy sources/renewable energy sources in large extent for electrical power generation. The use of the power electronic converters is important, when the renewable sources connecting to distribution system (3-phase 4-wire). This system is most economic and reliable when there are maximum benefits from grid interfacing inverters. This grid interfacing inverters thus can be utilized multifunction device as- 1) Power converter to supply generated power from RES to grid, and 2) Shunt active power filter for compensating distort current, harmonics at load side, reactive power support for load, load neutral current. These multifunction’s may be either accomplished individually or simultaneously. With the use of this technique grid interfacing inverters and 3-phase 4-wire, linear or non-linear unbalanced load combination at point of common couple (PCC) appears as a balanced linear load to the grid. This control technique is to be simulated in MATLAB.
