Influence of Photovoltaic Power Plants Based on VSG Technology on Low Frequency Oscillation of Multi-Machine Power Systems

IEEE Transactions on Power Delivery, 2022
With the increase of photovoltaic penetration, the power-electronic converter (PEC)-interfaced generators with traditional control strategy may cause severe power oscillations after being disturbed due to lack of inertia and damping.

Low Frequency Oscillation Analysis of VSG Grid-Connected System

2021 3rd Asia Energy and Electrical Engineering Symposium (AEEES), 2021
Due to that VSG (virtual synchronous generator) simulates the operation characteristics of SG (synchronous generator), similar stability issue that is common in traditional power system may also exist in VSG grid-connected system.

The Impact of Wind Generation on Low Frequency Oscillation in Power Systems

2021 IEEE PES/IAS PowerAfrica, 2021
Integration the renewable energy resources (RES) with the modern power system is increased in the last decays due to its environmental and economic benefits. In contrast these technologies impact on the dynamic behavior of the power system. In this paper,

Real-time low-frequency oscillations monitoring

Journal of Renewable and Sustainable Energy, 2021
A major concern for interconnected power grid systems is low-frequency oscillation, which limits the scalability and transmission capacity of power systems. Undamped or poorly damped oscillations will lead to undesirable conditions or even a catastrophic system blackout.

Study on DFIG Dissipation Energy Model and Low-Frequency Oscillation Mechanism Considering the Effect of PLL

IEEE transactions on power electronics, 2020
Considering the dynamic characteristics of phase-locked loop (PLL), the effect of interaction between doubly fed induction generator (DFIG) and power grid on system low-frequency oscillation is revealed from the perspective of dissipation energy.

An Approach to Suppress Low-Frequency Oscillation by Combining Extended State Observer With Model Predictive Control of EMUs Rectifier

IEEE transactions on power electronics, 2019
Recently, low-frequency oscillation (LFO) occurs in electrified railways, which exhibits a synchronous periodic oscillation of about 2–7 Hz in the traction network and electric multiple units (EMUs).

A low frequency oscillator structure

2009 European Conference on Circuit Theory and Design, 2009
We propose a novel RC sinusoidal oscillator architecture suitable for very low frequency generation. The oscillator is also attractive in the sense that the lower the oscillation frequency, the lower the necessary gain required to start oscillations. Further, the proposed architecture is active-circuit-independent and can be realized in any suitable ...

A Passivity-Based Control of Euler–Lagrange Model for Suppressing Voltage Low-Frequency Oscillation in High-Speed Railway

IEEE Transactions on Industrial Informatics, 2019
The traction network voltage low-frequency oscillation (LFO) in high-speed railways easily leads to the traction blockade of electric multiple units (EMUs), which seriously affects the normal operation of high-speed railways.
