Pekan Olahraga Nasional (PON) yang diselenggarakan di Stadion Harapan Bangsa menyebabkan peningkatan beban listrik yang signifikan pada sistem distribusi PLN UP3 Banda Aceh. Penelitian ini dilakukan untuk membandingkan kondisi sistem distribusi listrik sebelum dan selama pelaksanaan PON dengan menggunakan simulasi aliran daya (Load Flow Analysis) pada perangkat lunak ETAP. Sebelum PON, tegangan pada beberapa titik beban mengalami penurunan, seperti di Venue Sepak Bola (371 V), Angkat Besi (364 V), dan Anggar (372 V). Total daya aktif tercatat sebesar 1.107 kW, dan beberapa titik mengalami penurunan tegangan hingga 4,21%. Kondisi ini menunjukkan bahwa sistem berpotensi mengalami penurunan performa akibat beban berlebih. Ketika PON berlangsung dan generator cadangan diterapkan, tegangan terminal di seluruh venue meningkat dan stabil di sekitar 380 V. Daya aktif naik menjadi 1.134 kW, dan seluruh tegangan berada dalam rentang normal. Beban yang disuplai juga sesuai dengan kapasitas generator, sehingga sistem dapat beroperasi tanpa gangguan berarti. Hasil ini menunjukkan bahwa penerapan sistem islanding dengan generator cadangan efektif dalam menjaga kestabilan tegangan dan kontinuitas suplai listrik selama pelaksanaan PON. Sistem ini dapat digunakan sebagai strategi teknis untuk mendukung acara besar di masa mendatang.

The National Sports Week (PON) held at Harapan Bangsa Stadium caused a significant increase in electrical load on the PLN UP3 Banda Aceh distribution system. This study was conducted to compare the condition of the distribution system before and during the PON event using Load Flow Analysis simulations in the ETAP software. Before the PON, voltage drops occurred at several load points, such as the Football Venue (371 V), Weightlifting Venue (364 V), and Fencing Venue (372 V). The total active power recorded was 1,107 kW, and several points experienced voltage drops of up to 4.21%. This indicates a potential decline in system performance due to excessive load. During the PON, when backup generators were deployed, the terminal voltages at all venues increased and stabilized at around 380 V. The active power rose to 1,134 kW, and all voltages remained within the normal range. The supplied loads were also within the generator capacity, allowing the system to operate without significant disturbances. These results demonstrate that the implementation of an islanding system with backup generators is effective in maintaining voltage stability and continuity of power supply during the PON event. This approach can serve as a technical strategy to support future large-scale events.
