The ever increasing wind energy penetration into the utility grid causes challenges in the power quality (PQ) of the electrical supply. Therefore, this work proposed PQ assessment in the utility grid which is interfaced with the wind energy generation using Stockwell's transform (ST) under various operating events. The experimental set-up for assessing the PQ included an emulated wind generator synchronised with the utility grid at the point of common coupling. The current and voltage measurements are carried out using PQ analyser associated with WTViewer application software. The recorded signals of the voltage waveforms are assessed using ST to detect the various PQ issues related to the grid integration and wind generator's outage. To investigate the effects of various types of loads on the PQ, the same events are carried out. Various PQ disturbances are successfully detected using the proposed algorithm. Performance of the proposed algorithm is also tested on the grid integrated solar photovoltaic (PV) system to investigate and compare the PQ disturbances associated with the grid integrated solar PV system.
