If generation is smaller than load, system frequency will drop. When generation deficiency is too large, system frequency will decrease significantly which can lead to system blackout. To solve this frequency issue, proper under-frequency load shedding and also islanding scheme is essential to prevent continuous decreasing of system frequency. In this paper, conventional under-frequency load shedding and islanding scheme based on generator coherency is designed for Sulawesi Selatan-Tenggara-Barat (Sulselrabar) system, one of power system in Sulawesi, Indonesia. Sulselrabar system isn’t too large with peak load of about 800 MW therefore application of conventional under-frequency load shedding and islanding scheme is adequate. All simulations in this paper were performed using DIgSILENT Power Factory. © 2012 IEEE.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Generator coherencies,Islanding,Power imbalance,Under frequencies,Underfrequency load-shedding[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]conventional underfrequency load shedding scheme,generator coherency,islanding,power imbalance,under-frequency[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/CMD.2012.6416384[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
