Grid Forming Inverters for Ride-Through of Symmetric and Asymmetric Faults
The integration of power electronic converters, local renewable generation, load, and/or storage is currently finding widespread applications in microgrids, electric ships, drone delivery, electric vehicle fast chargers, large scale data centers, and commercial/industrial buildings bringing the benefits of high efficiency, power quality, flexibility, stability, and reliability. The modern customers will interact with the utility by enabling distributed generation, microgrids and the integration of electronic loads. The emerging prosumers (i.e., producer plus consumer) are expected to interact with the provider or utility based on economic, social, environmental and security considerations. On the technical aspect, grid-forming (GFM) inverters are believed to be the key enabling technology for high penetration of power electronics interfaced resources into the bulk power system. Furthermore, grid-forming capability is critical for resilient microgrids where the majority of power generating modules may be inverter-interfaced. Controlling and predicting the behavior of the GFM converter during symmetric and asymmetrical fault is critical for resilient system operation. Ride-through of symmetrical and asymmetrical faults remain one of the key challenges for GFM converters till date. This seminar will give an overview of the fault ride through requirements in a GFM inverters followed by symmetrical and asymmetrical ride through achieved using the unified virtual oscillator control method (UVOC) developed at the FREEDM Center in North Carolina State University.
