Autonomous Grid-Forming Inverter Exponential Droop Control for Improved Frequency Stability
Rick Wallace Kenyon, Amirhossein Sajadi, Bri-Mathias Hodge
This paper introduces the novel Droop-e grid-forming power electronic converter control strategy, which establishes a non-linear, active power--frequency droop relationship based o…
Semi-Supervised Multi-Task Learning Based Framework for Power System Security Assessment
Muhy Eddin Za'ter, Amirhossein Sajadi, Bri-Mathias Hodge
This paper develops a novel machine learning-based framework using Semi-Supervised Multi-Task Learning (SS-MTL) for power system dynamic security assessment that is accurate, relia…
Foundation Models for the Electric Power Grid
Hendrik F. Hamann, Thomas Brunschwiler, Blazhe Gjorgiev +24
Foundation models (FMs) currently dominate news headlines. They employ advanced deep learning architectures to extract structural information autonomously from vast datasets throug…
Acceleration of Power System Dynamic Simulations using a Deep Equilibrium Layer and Neural ODE Surrogate
Matthew Bossart, Jose Daniel Lara, Ciaran Roberts +3
The dominant paradigm for power system dynamic simulation is to build system-level simulations by combining physics-based models of individual components. The sheer size of the sys…
Lunar Power Grid: Network Structure and Spontaneous Synchronization
Mark Walth, Amir Sajadi, Marc Carbone +1
Achieving stable synchronized operation in an alternating current power network is critical to the continuity and reliability of energy delivery. In this paper, we study a dynamic…
Plane Wave Dynamic Model of Electric Power Networks with High Shares of Inverter-Based Resources
Amirhossein Sajadi, Bri-Mathias Hodge
Contemporary theories and models for electric power system stability are predicated on a widely held assumption that the mechanical inertia of the rotating mass of synchronous gene…
Towards Robust and Scalable Dispatch Modeling of Long-Duration Energy Storage
Omar J. Guerra, Sourabh Dalvi, Amogh A. Thatte +3
Existing modeling approaches for long-duration energy storage (LDES) are often based either on an oversimplified representation of power system operations or limited representation…
