Table 1 Comparison of several types of SCR.

From: Research on the configuration strategy of active support long-and short-term energy storage devices based on ESD-considered short circuit ratio

Type of SCR

Consider RES

Consider ESD

Shortcoming

SCR

No

No

Ignore multiple RESs interactions

WSCR

Yes

No

Assuming a single bus, only evaluate the overall strength

gscr/CgSCR

Yes

No

Not considering the impact of ESD

SDSCR

Yes

No

Not considering the impact of ESD

ISCR

Yes

Not comprehensive

Without considering the contribution of ESD to short- circuit capacity, instantaneous stability cannot be reflected

ECSCR

Yes

Yes
