Through mutual interaction, converters become more prone to instability under certain conditions.
This paper points out that the overall system stability should be re-considered in the light of a more complete model that takes into account the interaction of converters connected to the grid at a common point of coupling.
The harmonic and inter-harmonic interaction at each converter station depended on the characteristic of the converter its own is also affected by the interaction from the other converter stations.
Moreover, the harmonic interaction at each converter station is not only affected by other harmonic interaction at the other converter stations in the system, and this should be investigated in more detail.
As can be seen that, the dc grid is a complex system where harmonic interaction of each converter station is not only affected by its self but also affected by other converter stations.
SNP sites at R707 and R710 are highly conserved among myosin isoforms but do not appear to enter into the crucial interaction with the converter domain.
Highly conserved residues on the tip of the switch 2 helix, Y504 and I509, are thought to mediate interaction with the converter domain but are not affected by known SNPs. Figure 3 shows the SNP substitutions sites for the SH2/SH1 hinge [M688V, V694E (L694 in MYH1), R695H (H695 in MYH1), G701R, R707S, R710S], converter [R743Q (K743 in MYH1)], and lever-arm [L785M and D787N (Q787 in MYH1)].
2, we take a quick tour of the instability phenomenon arising from converters' interaction.
First, a dynamic model of the PEFC stack, valid for high frequencies and compatible with power converter interactions, has been developed.
Since the tip of the relay-helix is connected via hydrogen bonds and hydrophobic interactions with the converter, the relatively small switch 2 movement is amplified via the relay helix to a 65° rotation of the converter and a swinging of the lever arm from the initial down to the up position.
These conditions are mostly created by the application of severe and frequent load peaks or by the interactions with power converters' current harmonics.
