Power quality (PQ) is very important to ICT industry, Data Centres and Digital Transformation. Recently, there is an increase Renewable Energy (RE) penetration into the grid, Electrification of Transportation sector through increase in use of Electric Vehicles (EV) and EV Charging stations in the distribution system to reduce carbon emission. This requires more attention to Power Quality as RE and EV integration in distribution brings more PQ issues such as Supraharmonics, Voltage Flicker and Voltage Distortion. Study of the power quality phenomenon in the Smart Grid requires advanced signal processing methods both for measurement and analysis. The application of Time-Frequency Analysis and Machine Learning for the study of power quality and diagnostics will become more essential than ever. This webinar will discuss the future of Power Quality in Smart Grid and revision of IEEE PQ standard 1159.
