6 FAQs about [Sunshine Microgrid Oscillation]

Why are low frequency oscillations a problem in grid-connected microgrids?

However, the grid-connected microgrid operation presents challenges to the stability of the main grid. Due to small aggregated physical inertia of these microgrid, there is a significant deviation in system inertia that contributes to low frequency oscillations (LFO). These oscillations have a significant risk to power system stability.

Does FCS-MPC improve low-frequency oscillation stabilization of PV-based microgrids?

Can low-inertia mg control voltage and frequency oscillations?

The control of voltage and frequency oscillations has presented significant challenges and the dynamic interaction between low-inertia MG and conventional power grid. Modern power systems comprise numerous low-inertia MG interconnected with the traditional power grid.

What is VSG-related low-frequency oscillation?

Various mechanisms of virtual synchronous generator (VSG)-related low-frequency oscillation (LFO) are classified and compared with the traditional synchronous generator-related LFO. Modeling, analysis methods and suppression strategies for the VSG-related LFO are reviewed and compared. Future research trends for the VSG-related LFO are presented.

What is a small signal equivalent model of synchronous generator-based grid-connected microgrid?

Int J Electric Power Energy Syst 108:263–270 Mol EJ, Linda MM (2023) Integration of wind and PV systems using genetic-assisted artificial neural network.

Does low-frequency oscillation damage a VSG?

However, low-frequency oscillation (LFO) is introduced as a side effect owing to the second-order oscillation characteristics of the VSG. If not properly damped, the oscillation may damage the VSG because of its low overcurrent capability; thus, this issue has attracted considerable attention from both academia and industry.
