Impact of communication delay on distributed load frequency control (dis-LFC) in multi-area power system (MAPS) [PDF]

Malaysian Journal of Fundamental and Applied Sciences, 2019
AIn this paper, impact of communication delay on distributed load frequency control (dis-LFC) of multi-area interconnected power system (MAIPS) is investigated. Load frequency control (LFC), as one of ancillary services, is aimed at maintaining system frequency and inter-area tie-line power close to the scheduled values, by load reference set-point ...
