Placement of virtual inertia from HVDC terminals based on a frequency deviation index [PDF]
, 2021 This paper presents an approach for assessing the most suitable locations to provide virtual inertia by HVDC converters. A frequency deviation index quantifying the maximum distance in Hz from each bus in the power system to the Center of Inertia (COI ...

Optimal Allocation of Virtual Inertia Devices for Enhancing Frequency Stability in Low-Inertia Power Systems [PDF]
2021 North American Power Symposium (NAPS), 2021 As renewable resources gradually replace conventional generation based synchronous machines, the dynamics of the modern grid changes significantly and the system synchronous inertia decreases substantially. This transformation poses severe challenges for power system stability; for instance, it may lead to larger initial rate of change of frequency and

Virtual Inertia as an Energy Dissipation Element for Haptic Interfaces [PDF]
IEEE Robotics and Automation Letters, 2022 Adding virtual damping to dissipate energy has been a major tool for designing stable haptic interfaces in most passivity-based approaches. However, virtual damping is known to dissipate a limited amount of energy. It even generates energy during high-velocity interaction because of the digitization effect, such as zero-order hold and quantization ...
