Active Power Oscillation Suppression Based on Decentralized Transient Damping Control for Parallel Virtual Synchronous Generators

IEEE Transactions on Smart Grid, 2023
Similar to the traditional synchronous generator (SG), a drawback of the virtual synchronous generator (VSG) is the active power oscillation, especially in the system with parallel VSGs.

Evaluation of Virtual Synchronous Generator Compared to Synchronous Generator

2020 IEEE Power & Energy Society Innovative Smart Grid Technologies Conference (ISGT), 2020
Virtual synchronous generator (VSG) can be designed to aid the integration of large-scale distribution generation (DG) such as photovoltaic into the power grid. Through this concept, it is plausible for the DG to exhibit the characteristics and behavior of synchronous generators (SG) such as inertia, droop functions and damping.

A Framework for Observer-Based Robust Fault Detection in Nonlinear Systems With Application to Synchronous Generators in Power Systems

IEEE Transactions on Power Systems, 2022
A nonlinear robust fault detection scheme for synchronous generators in power systems is presented. The higher-order model of a synchronous generator having nonlinearity in dynamics is considered. A nonlinear observer-based fault detection (FD) scheme is
