Abstract

Photovoltaic (PV) system as one part of distributed energy resources is becoming an alternative for low and medium distribution network of microgrid. By the reason of a wide implementation of power electronic and non-linear loads, harmonics distortion is one of the main problems for the power systems. There are several filter types to mitigate the harmonics. The passive filter is distinguished by its simplicity and economical options from another filters. In this paper, the passive single tuned filter (STF) is used to minimize harmonics distortion in standalone PV based microgrid. A solar PV array is modelled as an ideal single diode model (ISDM) and used to supply electrical power to an AC load. The simulation results are executed on MATLAB/Simulink show that STF is effective in mitigating the voltage total harmonic distortion (VTHD) and the current total harmonic distortion (ITHD) with enhancing the output power quality.
