Virtual Oscillator Control of Equivalent Voltage-Sourced and Current-Controlled Power Converters
The dynamics of a general class of weakly nonlinear oscillators can be used to control power converters to create a self-forming AC network of distributed generators. Many control stability results
Three Phase Dead-Zone Oscillator Control Under Unbalanced Load Conditions
TLDR
Understanding the characteristics of this type of oscillator and applying it to unbalanced loads will help to further the process of implementing these small self-sustaining converters into larger networks with little to no adverse effects.
Dead Zone Oscillator Control for Communication-Free Synchronization of Paralleled, Three-Phase, Current-Controlled Inverters
Abstract : The prevalence of converter-interfaced power sources in the power grids of both civilian and military systems is increasing due to technological improvements in power conversion and
Adaptation of Commercial Current-controlled Inverters for Operation with Virtual Oscillator Control
TLDR
Off-the-shelf commercial inverters with current control can be reprogrammed to behave as voltage sources with virtual oscillator dynamics for deployment in islanded settings and improved voltage regulation due to the additional voltage control loop is shown.

Oscillator-Based Inverter Control for Islanded Three-Phase Microgrids
TLDR
Time-domain switching-level simulation results for a 45-kW microgrid with 33% PV penetration demonstrate the merits of the proposed technique; in particular they show that the load voltage can be maintained between prescribed bounds in spite of variations in incident irradiance and step changes in the load.
Power-System Frequency and Stability Control using Decentralized Intelligent Loads
Modern power systems operate on the premise that the load is uncontrollable and that system voltage, frequency and stability are primarily maintained through control of the generation. In this paper,
Synchronization of Parallel Single-Phase Inverters With Virtual Oscillator Control
TLDR
A sufficient condition for global asymptotic synchronization is outlined and a methodology for controller design is formulated such that the inverter terminal voltages oscillate at the desired frequency, and the load voltage is maintained within prescribed bounds.

This paper presents the development of a real-time Optimal Power Flow (OPF) management system which is implemented in the Smart Grid Test-bed lab at Florida International University and will discuss briefly the developed Hybrid AC/DC microgrid and its components.
Synchronization of Nonlinear Oscillators in an LTI Electrical Power Network
TLDR
Sufficient conditions are derived for the global asymptotic synchronization of a class of identical nonlinear oscillators coupled through a linear time-invariant network and this work facilitates a modular design approach because the synchronization condition is independent of the number of oscillators.

Synchronization in complex oscillator networks and smart grids
TLDR
This work presents a unique, concise, and closed-form condition for synchronization of the fully nonlinear, nonequilibrium, and dynamic network of a strongly coupled and sufficiently homogeneous network.
