Technical impacts of high penetration levels of wind power on power system stability

Advances in Energy Systems, 2017
With increasing penetrations of wind generation, based on power‐electronic converters, power systems are transitioning away from well‐understood synchronous generator‐based systems, with growing implications for their stability.

Influence mechanism and virtual power system stabiliser method of virtual synchronous generator for low‐frequency oscillation of power system

IET Energy Systems Integration
The virtual synchronous generator (SG) (VSG) can not only enhance the inertia of the grid, but also introduce the oscillation characteristics of SG, which is easy to interact with the power angle of SG in the grid, and even produce low‐frequency ...

An optimizated additional damping control for suppressing ultra‐low frequency oscillation suppression based on SVC

IET Renewable Power Generation
The ultra‐low frequency oscillation (ULFO) imposes an emerging stability challenge to the high proportion of hydropower grids. To suppress ULFO without reducing the primary frequency regulation of the hydro governor, a novel idea to exploit the voltage ...

Determining the Load Inertia Contribution from Different Power Consumer Groups

Energies, 2020
Power system inertia is a vital part of power system stability. The inertia response within the first seconds after a power imbalance reduces the velocity of which the grid frequency changes.

Dynamic reactive power reserve assessment method for hybrid AC/DC networks based on a reduced equivalent model of an LCC‐HVDC converter process

IET Renewable Power Generation
LCC‐HVDC technology has been widely applied. Commutation failure is a common disturbance in converter stations. In the absence of an adequate and rapid dynamic reactive power supply, the system is prone to trigger DC blocking.
