Abstract:Short circuit models of transmission networks have not commonly included loads. The reason is that the fault current from synchronous generators are many times higher than the load current and highly reactive, and hence omission of load current does not reduce the accuracy of short circuit results. Nevertheless, this modeling practice may no longer be appropriate to an inverter-based resource (IBR)-dominated grid or grid region; the fault current of an IBR is comparable to load current and, depending on invert… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
