Derivation to explain the relation between the Short Circuit Ratio (SCR) and the static voltage stability. A novel power system strength index is proposed to assess power system strength in the presence of reactive power injection. The novel index is validated on both positive sequence modelling and electro-magnetic transient type software.
SCR does not correctly reflect the power system strength when multiple IBRs are already present at the vicinity of the PoC and when there are reactive power compensation devices such as SVCs. This makes SCR index not sufficient to provide an exact situation of system strength with IBRs.
The SDSCR index shows the relationship between the voltage stability boundary and its relationship with power system strength , . At the voltage collapse point, the SDSCR is 1 and it is >3 for a strong bus while its value less than 3 for a bus provides an indication as a weak bus.
A generalized SCR index and its critical value for new energy grid-forming systems are put forward in [27, 28], thereby achieving a quantitative evaluation of system strength. However, the aforementioned calculations of SCR considering new energy stations along with their voltage support capability are still incomplete.
In power systems dominated by synchronous generators, the SCR has been widely used to estimate the system strength by using short-circuit level information obtained at the relevant bus.
This new power system strength index can be used by power system planners to reduce the number of EMT type simulations done for extended hours and could be used for online power system strength determination.
