Model Reduction for Inverters with Current Limiting and Dispatchable Virtual Oscillator Control
Olaoluwapo Ajala, Minghui Lu, Brian Johnson +2
This paper outlines reduced-order models for grid-forming virtual-oscillator-controlled inverters with nested current- and voltage-control loops, and current-limiting action for ov…
Singular Perturbation and Small-signal Stability for Inverter Networks
Saber Jafarpour, Victor Purba, Sairaj V. Dhople +2
This paper examines small-signal stability of electrical networks composed dominantly of three-phase grid-following inverters. We show that the mere existence of a high-voltage pow…
Dispatchable Virtual Oscillator Control for Decentralized Inverter-dominated Power Systems: Analysis and Experiments
Gab-Su Seo, Marcello Colombino, Irina Subotić +3
This paper presents an analysis and experimental validation of dispatchable virtual oscillator control (dVOC) for inverter-dominated power systems. dVOC is a promising decentralize…
Uncovering Droop Control Laws Embedded Within the Nonlinear Dynamics of Van der Pol Oscillators
Mohit Sinha, Florian Dorfler, Brian B. Johnson +1
This paper examines the dynamics of power-electronic inverters in islanded microgrids that are controlled to emulate the dynamics of Van der Pol oscillators. The general strategy o…
Optimal Dispatch of Residential Photovoltaic Inverters Under Forecasting Uncertainties
Emiliano Dall'Anese, Sairaj V. Dhople, Brian B. Johnson +1
Efforts to ensure reliable operation of existing low-voltage distribution systems with high photovoltaic (PV) generation have focused on the possibility of inverters providing anci…
Decentralized Optimal Dispatch of Photovoltaic Inverters in Residential Distribution Systems
Emiliano Dall'Anese, Sairaj V. Dhople, Brian B. Johnson +1
Decentralized methods for computing optimal real and reactive power setpoints for residential photovoltaic (PV) inverters are developed in this paper. It is known that conventional…
Synchronization of Nonlinear Circuits in Dynamic Electrical Networks with General Topologies
Sairaj Dhople, Brian Johnson, Florian Dorfler +1
Sufficient conditions are derived for global asymptotic synchronization in a system of identical nonlinear electrical circuits coupled through linear time-invariant (LTI) electrica…
