Distributed Droop-Free Control of Grid-Forming Inverters with Dynamic Line and Load Modeling
Hiya Akhil Gada, Marija Ilic
Droop-free distributed control has emerged as a promising alternative to conventional linear droop control for coordinating inverter-based resources in AC microgrids. However, exis…
Distributed component-level modeling and control of energy dynamics in electric power systems
Hiya Gada, Rupamathi Jaddivada, Marija Ilic
The widespread deployment of power electronic technologies is transforming modern power systems into fast, nonlinear, and heterogeneous networks. Conventional modeling and control…
Slow Inter-area Electro-mechanical Oscillations Revisited: Structural Property of Complex Multi-area Electric Power Systems
Hiya Akhil Gada, Marija D. Ilic
This paper introduces a physically-intuitive notion of inter-area dynamics in systems comprising multiple interconnected energy conversion modules. The idea builds on an earlier ge…
Equivariant Filters are Equivariant
Hiya Gada, Pieter van Goor, Ravi Banavar +1
Observers for systems with Lie group symmetries are an active area of research that is seeing significant impact in a number of practical domains, including aerospace, robotics, an…
