Collective inertia of Nambu-Goldstone mode from linear response theory [PDF]

open access: yesPhysical Review C, 2015
Background: Spurious zero-energy Nambu-Goldstone (NG) modes appear when the symmetry of a system is spontaneously broken. The Thouless-Valatin inertia, the collective inertia of the NG mode, contains important information concerning collective motion ...

Cost Allocation for Inertia and Frequency Response Ancillary Services [PDF]

open access: yesIEEE Transactions on Energy Markets, Policy and Regulation, 2023
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.

Inertia estimation of new energy power system with virtual inertia response of wind power

open access: yes电力工程技术, 2023
The accurate estimation of inertia is the premise of analyzing the security and stability of the system frequency, but the existing methods can not quantitatively evaluate the effect of virtual inertia on the equivalent inertia of the power system.

Dynamic Coordination Mechanism of DFIGs Based on Inertia Response

open access: yesZhongguo dianli, 2022
Large-scale wind power integration occupies the capacity space of synchronous generators with moments of inertia and weakens the inertia level and frequency regulation ability of the power system.

Optimal Portfolio of Distinct Frequency Response Services in Low-Inertia Systems [PDF]

open access: yesIEEE Transactions on Power Systems, 2019
A reduced level of system inertia due to renewable integration increases the need for cost-effective provision of ancillary services, such as Frequency Response (FR).

Interconnected microgrids frequency response model: An inertia-based approach

open access: yesEnergy Reports, 2020
Preserving the frequency stability of new important blocks in smart grids such as interconnected microgrids, is a serious challenge. Inertia can act as a significant stability/performance index for frequency regulation in the power grids.

Stochastic scheduling with inertia-dependent fast frequency response requirements [PDF]

open access: yes2016 IEEE Power and Energy Society General Meeting (PESGM), 2016
High penetration of wind generation will increase the requirement for fast frequency response services as currently wind plants do not provide inertial response. Although the importance of inertia reduction has been widely recognized, its impact on the system scheduling has not been fully investigated. In this context, this paper proposes a novel mixed

Influence of wind turbine inertia support on frequency drop characteristics of power grid

open access: yesZhejiang dianli, 2023
With the increasing penetration of new energy sources in large synchronous grids, renewable generator units that do not have inertial response capability may undermine the inertia of the system.

Flexible Power Point Tracking Using a Neural Network for Power Reserve Control in a Grid-Connected PV System

open access: yesEnergies, 2022
Renewable energy penetration in the global energy sector is in a state of steady growth. A major criterion imposed by the regulatory boards in the wake of electronic-driven power systems is frequency regulation capability.
