Abstract :
Harmonic reduction in inverters fed from a standalone PV system is currently becoming important in medium power applications. This paper focuses on the design and analysis of various passive filters for power quality improvement in standalone PV systems. Different passive filters are designed and analysed to reduce the total harmonic distortion of the proposed system. The passive filters include LC, LCL and LLCC filter topologies. A comparison study of the total harmonic distortion reduction with the above filters is done. Further, the paper attempts to show that the use of LLCC filter with a standalone PV system can highly improve the power quality of the system. Results are verified using simulations in MATLAB-SIMULINK environment.
