Virtual synchronous machine (VSM) technology is an attractive control method for an inverter-based distributed generation (DG) due to having the voltage, and frequency support functionality. Embedding an anti-islanding ...

Microgrids (MGs) have become an integral part of smart grid initiatives for future power system networks. Networked microgrids consist of several neighbouring microgrids connected in a low/medium distribution network. The ...

The high-voltage dc (HVDC) systems are appearing more and more, and it is becoming a requirement that the HVDC voltage-source converters (VSCs) operate both as an inverter and a rectifier without changing the controls to ...

This paper presents an impedance modeling and small-signal stability analysis of the grid-tied Universal Droop Control (UDC) inverter. The -impedance model of the UDC inverter is derived analytically and, which is verified ...

This paper presents a non-invasive approach for real-time grid impedance identification based on the principle of instantaneous frequency tracking of voltage and current harmonics already present in the system, by the use ...

The distributed generation (DG) inverters can operate in an islanded mode and a grid-connected mode. Under grid fault conditions, the inverter is disconnected from the main grid and operates in the islanded mode. When DG ...

In this paper, a novel Robust-Synchronization-Loop (RSL) is proposed to track the phase and frequency of the grid voltage. The method can be widely applied to the grid-connected converters in integration of distributed ...

The main objectives of this research work are to determine the underlying mechanisms leading to instability in a system with dominant presence of tightly regulated power electronics components and to identify the causal ...

A subsynchronous oscillation (SSO) phenomenon in a wind farm integrated with a modular multilevel converter (MMC)-based high-voltage direct current (HVDC) transmission system has been recently observed in the real world. ...
