Sustainability, 2017 Renewable energy sources (RESs), such as wind and solar generations, equip inverters to connect to the microgrids. These inverters do not have any rotating mass, thus lowering the overall system inertia.

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

The Virtual Inertia of Propellers Under Load
Journal of Ship Research, 1965Using a specially developed dynamometer, the hydrodynamic increase in inertia was determined for a variable-pitch propeller under load at various pitch settings and at various operating conditions. Tests also were carried out under "still-water" conditions.

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.

The increasing penetration of renewable energy sources reduces system inertia and challenges frequency stability, necessitating effective virtual inertia (VI) strategies. This paper proposes a disturbance-based framework to quantify and optimize VI by constructing bus-level inertia and damping matrices that capture the spatial distribution of inertia ...
