Locating the Source of Forced Oscillations in Transmission Power Grids
PRX Energy, 2023 Forced oscillation event in power grids refers to a state where malfunctioning or abnormally operating equipment causes persisting periodic disturbances in the system. While power grids are designed to damp most of perturbations during standard operations, some of them can excite normal modes of the system and cause significant energy transfers across ...

Location Method for Forced Oscillation Sources Caused by Synchronous Generators
CoRR, 2021 In this article, we present a new methodology to identify if forced oscillation sources are generated in excitation systems or in turbine governors. In this context, we propose to harness the information that the dynamic state estimation (DSE) provide to be able to apply a dissipating energy flow (DEF) method.

Fault Location Using the Natural Frequency of Oscillation of Current Discharge in MTdc Networks
IEEE Access, 2021 This paper discusses a novel offline-fault location approach using single ended measurements. The natural dissipation of the circuit parameters are considered for fault location.

Using Effective Generator Impedance for Forced Oscillation Source Location [PDF]
2019 IEEE Power & Energy Society General Meeting (PESGM), 2018 Locating the sources of forced low-frequency oscillations in power systems is an important problem. A number of proposed methods demonstrate their practical usefulness, but many of them rely on strong modeling assumptions and provide poor performance in certain cases for reasons still not well understood.

IEEE Open Journal of the Industrial Electronics Society, 2021 Existing impedance-based stability criterion (IBSC) for electromagnetic stability assessment of multiple-grid-connected-inverter (GCI)-based power systems suffers from several limitations. First, global stability feature is hard to be obtained if Nyquist-

Improving the prediction of the Madden–Julian Oscillation of the ECMWF model by post-processing [PDF]
Earth System Dynamics, 2022 The Madden–Julian Oscillation (MJO) is a major source of predictability on the sub-seasonal (10 to 90 d) timescale. An improved forecast of the MJO may have important socioeconomic impacts due to the influence of MJO on both tropical and extratropical ...

Design of process equipment exposure sources for ultrasonic absorption of greenhouse gases [PDF]
E3S Web of Conferences, 2023 The work aims at improving the efficiency of greenhouse gas utilisation processes, namely carbon dioxide. The principle of operation of the designed equipment is to realise the process of ultrasonic absorption (absorption of gas by liquid) when carbon ...
