Coordinated Control of HVDC and HVAC Power Transmission Systems Integrating a Large Offshore Wind Farm

Energies, 2019
The development of efficient and reliable offshore electrical transmission infrastructure is a key factor in the proliferation of offshore wind farms (OWFs). Traditionally, high-voltage AC (HVAC) transmission has been used for OWFs.

Impact of Digital Control Delay on Stability of Grid-Following Converters

2022 IEEE 13th International Symposium on Power Electronics for Distributed Generation Systems (PEDG), 2022
In a digital controlled system, the delay is inevitable. It will change the phase-frequency characteristics of the system, which will affect the stability. This paper analyzes the configuration of the grid-following converter and builds its small-signal model in detail.
