Overview
The transition towards a resilient zero-carbon electric power system is driven by a paradigm shift from conventional centralized bulk generation to decentralized renewable generation, power electronics, and microgrids. My work focuses on how to control a power system dominated by power electronics-interfaced renewable generation and maintain stability on the timescale of milliseconds to seconds.
Research
The electric power system is undergoing an unprecedented transition to a resilient 100% renewable zero-carbon power system that aims to curb carbon emissions and to ensure reliable and affordable access to electrical energy. At the heart of this transition is a technological paradigm shift from centralized thermal bulk generation connected to the grid via synchronous machines to distributed renewable generation interfaced to the grid via power electronics. Starting from a rigorous foundation in distributed control and optimization of complex networked systems my work focuses on bridging the gap between power system analysis / optimization and device-level control of power electronics / renewable generation in on converter-dominated power systems. Current research topics can be broadly categorized into two areas:
Next-generation grid-forming control of converter-interfaced renewable generation
Power converters with grid-forming control are envisioned to be the cornerstone of tomorrow’s resilient zero-carbon power system. To fully live up to this promise control algorithms for power converters are needed that can fully leverage the flexibility of a wide range of heterogeneous renewable generation technologies and ensure predictable fault ride-through behavior of power electronics-interfaced distributed renewable generation.
System-level resilience optimization and distributed control of converter-dominated systems
The transition to converter-dominated systems with massive integration of power electronics and renewable generation results in system-level questions ranging from identifying suitable performance and resilience metrics for optimization to optimizing the placement of devices providing grid-forming services, and ultimately how to efficiently coordinate millions of distributed flexible devices for which centralized coordination is no longer viable.
