Power Quality Monitoring of Grids with High Penetration of Power Converters


Abstract:The project aims to monitor and analyse power quality of grids within the frequency ranges of 0-2 kHz (existing regulations) and 2-150 kHz (new regulations). Power quality of grids deteriorate due to high penetrations of inverter based renewable energy systems. To estimate power quality of grids, a multi-domain simulation model based on grid configurations and operating conditions will be developed in this project. Developed methodologies will assist network service providers to better analyse harmonics and resonances within low and high voltage power systems and further support them to develop new planning guidelines and regulations to address power quality of grid connected solar inverters and wind turbines.

Addressing Challenges for the Future Grids - Harmonics Standardization


Due to the global demand for energy saving and reduction of greenhouse gas emissions, utilization of renewable energy sources and efficient loads based on power electronics technology is increased in electricity networks. The negative aspects of this technology are very complex and not well known which affect reliability and robustness of the grids. The main aims of this project are to: a) develop advanced tools for a better understanding of power quality issues of the residential, commercial and industrial distribution networks in Australia b) investigate and develop novel techniques to improve power quality and reliability of the grids c) develop harmonics emission and immunity levels and modify the Australian standards accordingly.

High Quality and Robust Energy Conversion Systems for Distribution Networks

 

The decreasing price of Wide Band Gap semiconductor devices offers an opportunity to revolutionize the next generation of energy conversion systems, such as in motor drives, solar inverters. However, the generation of high frequency harmonics by these devices affects the reliability, quality and safe operation of grids and grid connected equipment such as smart meters and communication signalling. The main aims of this research project are to protect low voltage distribution networks and reduce the harmonics and Electromagnetic Interference at the grid side. Further, the project aims to improve quality and efficiency of power converters through device level optimization with utilization of Wide Band Gap devices and multi-level topology.
