Abstract: Grid-forming converters are commonly envisioned to replace conventional synchronous generators as the cornerstone of future power systems. However, compared to synchronous generators, converter-interfaced generation is subject to significant limits (e.g., current limits, modulation limits, internal energy storage). Grid-forming controls are commonly designed neglecting these constraints and subsequently augmented with heuristic limiters. These heuristic limiters typically only allow to manage a subset of constraints. In this talk, a systematic approach to constrained grid-forming control is introduced. We first propose grid-forming control specifications under constraints that formalize the high-level objective of retaining as many grid-forming features as possible under constraints. Next, tools from optimization theory and projected dynamical systems are leveraged to design constrained grid-forming controls either from (i) basic specifications, or (ii) well-known (unconstrained) grid-forming controls.

Bio: Dominic Groß is an Assistant Professor with the Department of Electrical and Computer Engineering at the University of Wisconsin-Madison, Madison, WI, USA . He received his Ph.D. degree in Electrical Engineering from the University of Kassel, Germany, in 2014. Prior to joining UW-Madison, he was a postdoctoral researcher at the Automatic Control Laboratory of ETH Z ürich. He received an NSF CAREER award in 2022. His research interests include distributed control and optimization of complex networked systems with applications in dynamics of power systems dominated by power electronics, renewable generation, and energy storage.
