6 FAQs about [Energy storage harmonic resonance]
Does VSC affect harmonic resonance of power systems?
With the large integration of VSC-interfaced devices, there is a rising concern regarding their impact on the harmonic resonance of power systems. Meanwhile, other VSC-based applications such as flexible alternating current transmission systems (FACTS) are used for supporting the energy conversion of renewable energy.
How is a harmonic resonance model derived?
The harmonic resonance model is derived based on the penetration of a multifrequency harmonic, enabling it to fully reveal the frequency coupling effect in the system. Research has shown that frequency coupling plays an important role in harmonic resonance analysis.
What is the key factor in harmonic resonance analysis?
Research has shown that frequency coupling plays an important role in harmonic resonance analysis. The model is derived based on the penetration of a multifrequency harmonic, enabling it to fully reveal the frequency coupling effect in the system.
How can a VSC model be used for harmonic resonance analysis?
The VSC model for harmonic resonance analysis can be established by analyzing its response to the harmonic penetration from the AC side. Considering the frequency coupling effect, a multi-frequency harmonic penetration is essential.
Why does harmonic resonance occur near the 4th harmonic order?
As can be seen, harmonic resonance occurs close to the 4th harmonic order. Resonance results in an amplification of harmonic voltage distortion due to the large impedance interacting with the harmonic sources on the network. As both busbars are fed from the same supply point, causes for this resonance were investigated upstream.
Is harmonic resonance an issue in HREPPS?
Harmonic resonance is one of the most concerning power-quality problems in HREPPS.
