A programmable motor inertia changing scheme by utilizing virtual inertia
2008 IEEE Power Electronics Specialists Conference, 2008Large inertia is beneficial for constant speed operation, whereas low inertia is advantageous in the applications where rapid acceleration is necessary. But it is not easy to change the inertia physically. In this work, the method of increasing/decreasing inertia is proposed.

Fuzzy virtual inertia control for virtual synchronous generator
2016 35th Chinese Control Conference (CCC), 2016The virtual synchronous generator (VSG) control scheme regulates the inverter as a synchronous generator (SG). As the SG plays an important role in the conventional grid by supporting system stability, the VSG can act the same role in a micro-grid.

Virtual Power Plants and Virtual Inertia
2019In a general way, the electrical network is the set of lines, transformers and infrastructures that carry electricity from generation centers to final consumers. The current networks were designed and are in operation since the mid-twentieth century and were conceived to cover a situation in which the main generation centers were far from the ...

Emulation of Virtual Inertia with the Dynamic Virtual Damping in Microgrids
2019 International Conference on Applied Machine Learning (ICAML), 2019Following the modern trend of the energy policies, renewable energy sources are being integrated in the power network in a distributed environment through the power electronic mediums. In regards to electrical power, these interfacing mediums can efficiently couple micro sources and electrical loads, sacrificing the available inertia.

Modeling moment of inertia for virtual interactive environments
2004 IEEE Symposium on Virtual Environments, Human-Computer Interfaces and Measurement Systems, 2004. (VCIMS)., 2005Virtual environments have begun using algorithms to model the world around us more accurately by accounting for the mechanical behaviors and properties of objects. Amongst the properties for modeling objects which are used are the moment of inertia, the mass and the center of mass.

Synthesis of Robust Virtual Inertia Control
2020Regarding the previously elaborated inertia control techniques, they are not explicitly designed to deal with the effect of high uncertainty and disturbance. Thus, it is difficult to achieve a suitable trade-off between robust and nominal performances. In adaptive control techniques, the uncertainty formulation may not be appropriately included in the ...

An Overview of Virtual Inertia and Its Control
2020Today, due to the widespread penetration of renewable energy sources (RESs) and distributed generators (DGs), a new power system stability issue has emerged. This issue is the reduction and variation of inertia in the power system and is triggered by the utilization of power electronics interfaces to connect the RESs and DGs into the system, leading to

Virtual Torque and Inertia Loading of Controlled Electric Drive
IEEE Transactions on Education, 2005This work presents a simple method to obtain effects similar to those obtained by real mechanical loading and real inertia variation but without any mechanical parts supplementary to the electric motor of the studied electric drive. The electric motor itself produces the load torque and the inertia variation using digital signal processing software ...

Hybrid Transformers with Virtual Inertia for Future Distribution Networks
IECON 2019 - 45th Annual Conference of the IEEE Industrial Electronics Society, 2019Future distribution grids will require to integrate renewable energies in higher penetration levels than we are used to today in conventional power systems. To make this possible, key aspects of their operation such as reliability and robustness must been in safe levels.
