One of such contingency event is the violation of transmission line limits leading to the disconnection of multiple highly loaded transmission lines. To prevent this event, knowing the loadability of the transmission line is important. In this research, a method to obtain the loadability of the transmission line is proposed. The data from the phasor measurement units are utilized to obtain the characteristics of the transmission lines (i.e. reactance, voltage drop pattern). Then, the loadability of the transmission lines in terms of thermal, voltage drop, and stability limits are calculated. The adaptive remedial action scheme (RAS) is also designed to maintain power transfer within a safe limit by load shedding and/or generation rejection. This scheme will update the total amount of load shedding or generation rejection and select the target based on the sensitivity of voltage to active power change. The method is applied to the Java-Bali system, in which a high amount of power is transferred from eastern to the western part through the transmission lines at the north and south corridors and hence, knowing the loadability limits of each corridor is important. Using the proposed method, the separation of western and eastern Java could be effectively prevented.[/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]Contingency events,Highly loaded,Load-ability limits,Load-shedding,Power transfers,Remedial action scheme,Stability limit,Transmission line limits[/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]Adaptive remedial action scheme,Greedy algorithm,Loadability,Phasor measurement unit,Voltage sensitivity[/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/SEST48500.2020.9203187[/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]
