A VSG-Based Coordinated DC Voltage Control for VSC-HVDC to Participate in Frequency Regulation
Energies, 2021 In this paper, a coordinated DC voltage control strategy is proposed based on the VSG (virtual synchronous generator) method for the VSC-HVDC transmission system to participate in the frequency regulation of the connected weak grid. The voltage and power

Stability and frequency regulation of inverters with capacitive inertia [PDF]
2017 IEEE 56th Annual Conference on Decision and Control (CDC), 2017 In this paper, we address the problem of stability and frequency regulation of a recently proposed inverter. In this type of inverter, the DC-side capacitor emulates the inertia of a synchronous generator. First, we remodel the dynamics from the electrical power perspective.

Impact of variability, uncertainty and frequency regulation on power system frequency distribution [PDF]
2016 Power Systems Computation Conference (PSCC), 2016 This work originates from the observation of the frequency distribution of the Irish system as obtained from a Frequency Disturbance Recorder lent to the last author by the University of Tennessee. The probability density function of such a distribution appears to be bimodal.

Improved Frequency Control Strategy for Offshore Wind Farm Integration via VSC-HVDC
Energies, 2022 Voltage source converter based high voltage DC system (VSC-HVDC) has become a very promising solution to integrate offshore wind farm. However, the equivalent inertia of the modern power system with large renewable energy integration becomes small, which
