This paper presents an approach for the detection of power quality disturbances in smart grid associated with the events such as feeder tripping/reclosing, switching on/off of the capacitor banks and switching on/off the inductive-resistive (RL) loads. The distributed generation (DG) sources are integrated to the smart grid. The proposed study has been carried out using a standard IEEE-13 bus distribution network modelled as smart grid incorporated with wind and solar PV systems. The proposed test system is simulated using MATLAB software in simulink environment. Voltage signals captured at the point of common coupling (PCC) of the test system are decomposed using Stockwell's transform for power quality analysis. The harmonic detection has been carried out using Fast Fourier Transform. The power quality disturbances associated with the events under study have been investigated using the Stockwell transform based plots.
