Plane Wave Dynamic Model of Electric Power Networks with High Shares of Inverter-Based Resources

no code implementations30 Jan 2024 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 generators provides the sole contribution to stable and synchronized operation of this class of complex networks on subsecond timescales.

Droop-e: Exponential Droop as a Function of Power Output for Grid-Forming Inverters with Autonomous Power Sharing

no code implementations7 Jul 2022 Rick Wallace Kenyon, Amirhossein Sajadi, Bri-Mathias Hodge

This paper presents the novel Droop-e grid-forming inverter control strategy, which establishes an active power-frequency relationship based on an exponential function of the inverter power dispatch.

Hierarchical Control of Utility-Scale Solar PV Plants for Mitigation of Generation Variability and Ancillary Service Provision

no code implementations1 Jul 2021 Simon Julien, Amirhossein Sajadi, Bri-Mathias Hodge

Renewable energy technologies including solar and wind inevitably play a leading role in meeting the growing demand for a decarbonized and clean power grid.

Synchronization in Electric Power Networks with Inherent Heterogeneity Up to 100% Inverter-Based Renewable Generation

no code implementations8 Apr 2021 Amirhossein Sajadi, Rick Wallace Kenyon, Bri-Mathias Hodge

The synchronized operation of power generators is the foundation of electric power network stability and a key to the prevention of undesired power outages and blackouts.

Interactive Power to Frequency Dynamics Between Grid-Forming Inverters and Synchronous Generators in Power Electronics-Dominated Power Systems

1 code implementation24 Feb 2021 Rick Wallace Kenyon, Amirhossein Sajadi, Matt Bossart, Andy Hoke, Bri-Mathias Hodge

The primary system oscillatory mode confirms the correlation between high shares of grid-forming inverters and increased mode frequency and damping; a sharp decrease in damping is observed at shares above 80%, whether by grid-forming device quantity in large networks or rating variations in a small test system.
