The impact of slack bus fitness on the performance of South Sulawesi electrical systems at peak load conditions.

The continuity of electrical energy is inseparable from the reliability of the power system. In the event of a disruptive circumstance, the utilization of slack buses facilitates the transfer of functions from one primary source to another primary source. The Slack Bus is a solution aimed at mitigating the discrepancy between the load demand and the available producing capacity resulting from network losses. This study involved the simulation of the electric power system's operation by assigning the slack bus to three distinct locations, specifically bus-1 (Bakaru), bus-31 (Punagaya), and bus-37. The subject of discussion is Sengkang, a region in South Sulawesi. The simulation of the SULSELBAR 56-bus electrical system in the year 2022 was conducted using MATLAB 2013a software. The simulation results indicate that the smallest overall losses occur when Bus Sengkang is selected as the slack bus, with total losses amounting to 123.11 MW and 499.72 MVAr. [ABSTRACT FROM AUTHOR]
