Coordinated frequency support strategy for VSC-HVDC integrated offshore wind farm system

Frontiers in Energy Research
The large-scale offshore wind power integrated into the onshore power grid through voltage source converter-based high voltage direct current (VSC-HVDC) system is unable to provide inertia response and frequency support to the onshore power grid.

Learning-by-doing and Endogenous Price-level Inertia [PDF]

This paper presents a DGE model in which aggregate price level inertia is generated endogenously by the optimizing behaviour of price setting firms. All the usual sources of inertia are absent here ie., all firms are simultaneously free to change their ...

Cost Allocation for Inertia and Frequency Response Ancillary Services

IEEE Transactions on Energy Markets, Policy and Regulation
The reduction in system inertia is creating an important market for frequency-containment Ancillary Services (AS) such as enhanced frequency response (e.g.,~provided by battery storage), traditional primary frequency response and inertia itself.

A rotational speed recovery strategy for wind turbines considering secondary frequency drops

Zhejiang dianli
Wind turbines can contribute to frequency regulation by releasing rotor kinetic energy， which is an effective way to ensure frequency stability in power systems with high wind power penetration.

Absence of Pressure-Driven Supersolid Flow at Low Frequency

, 2009
An important unresolved question in supersolid research is the degree to which the non-classical rotational inertia (NCRI) phenomenon observed in the torsional oscillator experiments of Kim and Chan, is evidence for a Bose-condensed supersolid state with

Determinacy, learnability, and monetary policy inertia [PDF]

We document that monetary policy inertia can help alleviate problems of indeterminacy and non-existence of stationary equilibrium observed for some commonly-studied monetary policy rules.

Frequency stability control method for multi-energy system considering storage characteristics and transmission inertia of hot and gas pipeline network

Science and Technology for Energy Transition
The grid-connected capacity of renewable energy generation in multi-energy microgrid is increasing. This leads to a decrease in the inertia level in the microgrid, which has a great impact on the frequency stabilization control.

Fully quantum mechanical moment of inertia of a mesoscopic ideal Bose gas

, 2000
The superfluid fraction of an atomic cloud can be defined using the cloud's response to a rotation of the external potential, i.e. the moment of inertia.

A molecular superfluid: non-classical rotations in doped para-hydrogen clusters

, 2010
Clusters of para-hydrogen (pH2) have been predicted to exhibit superfluid behavior, but direct observation of this phenomenon has been elusive. Combining experiments and theoretical simulations, we have determined the size evolution of the superfluid ...
