Influence of Continuous Provision of Synthetic Inertia on the Mechanical Loads of a Wind Turbine
In many electrical grids, the share of renewable energy generation increases. As these generators are typically connected to the grid via inverters, the level of grid inertia decreases.

Broadband Cooperative Spectrum Sensing Based on Distributed Modulated Wideband Converter
The modulated wideband converter (MWC) is a kind of sub-Nyquist sampling system which is developed from compressed sensing theory. It accomplishes highly accurate broadband sparse signal recovery by multichannel sub-Nyquist sampling sequences.

VSC-HVDC for Frequency Support (a review) [PDF]
To reduce CO2 emissions produced by electricity generation, conventional fossil fuel power plants are being decommissioned. Renewable energy sources (RES) and interconnectors are replacing these old power plants but have different operating characteristics.

A Grouping-Based Frequency Support Scheme for Wind Farm Under Cyber Uncertainty
The injection of a significant amount of wind power tends to increase the difficulty of the grid frequency control. Therefore, wind farm (WF) has to have the ability to participate in system frequency support.

Frequency Modulation Control of Grid-Forming Converter Based on LADRC-MI
The increasing proportion of new energy in the power system leads to a decrease in system inertia and weakens the frequency stability of the system. The use of grid-forming (GFM) control for inverters is an effective method to improve frequency stability

Coordinated frequency support strategy for VSC-HVDC integrated offshore wind farm system
The large-scale offshore wind power integrated into the onshore power grid through voltage source converter-based high voltage direct current (VSC-HVDC) system is unable to provide inertia response and frequency support to the onshore power grid.
