Frequency Stability of Synchronous Machines and Grid-Forming Power Converters

Abstract: An inevitable consequence of the global power system transition towards nearly 100% renewable-based generation is the loss of conventional bulk generation by synchronous machines, their inertia, and accompanying frequency and voltage control mechanisms. This gradual transformation of the power system to a low-inertia system leads to critical challenges in maintaining system stability. Novel control techniques for converters, so-called grid-forming strategies, are expected to address these challenges and replic… Show more

“…The efficiency of a split criterion is further validated by calculating the drop of impurity at the ancestor nodes, as in (11). Here, t Y and t N are the two ancestor nodes corresponding to the Y es and N o branches, while N tY /N t and N tN /N t are the portion of samples at each of the these two nodes.…”

“…Due to the fast development of society and increasing requirement of sustainability, the modern power system becomes extremely large and complicated. Many major blackouts with tremendous loss both physically and economically have dedicated the power system stability issue to be a prominent research aspect in decades [6]- [8].…”

“…From 9, it is easy to find that the voltage derivation index is one if bus voltage equals to its nominal voltage, while the index equals to zero when bus voltage operates at any of its boundaries in (8). Therefore, the larger the voltage index is, the better the voltage stability.…”

“…However, the BPC discussed in this paper is used to regulate frequency in the AC subgrid, and it should be able to recover the AC bus frequency after the power fluctuation. Thus, a simplified speed governor controller is applied to get the P r [33]. The expression of the speed governor can be expressed as…”
