“…It can be clearly noticed that the summed type OEL has no impact on the stability margin. This is something which could be expected, since it has been characterized as "soft" in the literature [12], [31], because the limit imposed is influenced by the other inputs to the voltage regulators as well. On the other hand, the takeover OEL's influence on system stability margin is significant in some cases, making it considerably lower.…”

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.
