Abstract:
The introduction of Distributed Energy Resources such as energy storage systems, solar, and wind create system dynamics which modern electric grids cannot reliably handle in such large quantities without properly coordinated protections. One such tool is the concept of Fault Ride-Through, which allows a system to continue operation during a long-term minor or short-term major disturbance. Standards are in place to control and monitor the operation and recovery of this capability but are meant to be minimum or maximum requirements. Since these standards must be used nationally, or sometimes internationally, they tend to be left very flexible. The rise of inverter-based devices, however, means that stricter standards which provide better grid protections can be more easily achieved.
This thesis presents a comprehensive review of the inverter requirements inside IEEE 1547 regarding Voltage Fault Ride-Through, power quality, and recovery of these devices during fault conditions. It examines the technical requirements, discusses various techniques of implementation, and compares IEEE 1547 to other national and international standards. Several real-world case studies are included to highlight the consequences of inadequate Fault Ride-Through protocols, emphasizing the importance of robust inverter design and proper controller settings.
