Abstract
The renewable energy is seen as a solution against global warming & other environmental issues. A solar cell will provide maximum power at maximum power point (MPP). Moreover, the locus of MPP changes over a various range that depends on the PV array temperature & insolation intensity. The P&O based MPPT method is used to track MPP. This DC output voltage is inverted through into 3-phase AC and synchronised with AC grid. However these power electronic converters causes injection of harmonics in the system. Moreover, presence of non linear load in system will further inject harmonic current and as a consequence, there is a violation of IEEE-519-1992 limit. As a solution, fuzzy logic based Shunt Active Power Filter (FLC-SAPF) is proposed. The FLC-SAPF will keep THD below 5%. The effect of sudden change in non linear load and variation in solar insolation should also taken into consideration.
