On-Line Inertia Estimation for Synchronous and Non-Synchronous Devices

IEEE Transactions on Power Systems, 2021
This paper proposes an on-line estimation method able to track the inertia of synchronous machines as well as the equivalent, possibly time-varying inertia from the converter-interfaced generators.

A Dual-Adaptivity Inertia Control Strategy for Virtual Synchronous Generator

IEEE Transactions on Power Systems, 2020
The virtual synchronous generator (VSG) improves the robustness of the inverter-interfaced distributed generator (IIDG) against instability by introducing a virtual inertia.

Frequency Control and Optimal Operation of Low-Inertia Power Systems With HVDC and Renewable Energy: A Review

IEEE Transactions on Power Systems
With the integration of large-scale renewable energy sources (RES) and high voltage direct current (HVDC) based inter-regional transmission, modern power systems are facing low-inertia issues and poor frequency regulation capabilities.

Coordinated Control Strategy of Virtual Synchronous Generator Based on Adaptive Moment of Inertia and Virtual Impedance

IEEE Journal on Emerging and Selected Topics in Circuits and Systems, 2021
The application of virtual synchronous generators in the power system eases the pressure on the grid caused by penetration of lots of power electronic devices, but worsens the dynamic frequency stability of the grid.

Synthetic Inertia Control of Grid-Connected Inverter Considering the Synchronization Dynamics

IEEE transactions on power electronics, 2021
The increasing penetration of renewable energy resources facilitates the carbon footprint reduction process yet reduces the power system inertia. As a result, the grid frequency and the rate of change of frequency (RoCoF) might probably go beyond the ...

Measurement-Based Estimation of Inertia in AC Microgrids

IEEE Transactions on Sustainable Energy, 2020
This paper presents an improved method to estimate the available inertia in an islanded AC microgrid. Inertia estimation is carried out based on measured frequency response for any arbitrary disturbance that occurs in the system.

An Inertia and Damping Control Method of DC–DC Converter in DC Microgrids

IEEE transactions on energy conversion, 2020
In DC microgrids, the inherent inertia from DC capacitors is low and the DC bus voltage is susceptible to power fluctuations, which results in low DC voltage quality. In this article, an inertia and damping control (IDC) method is proposed and applied in
