Abstract

Permintaan energi listrik yang terus meningkat serta keterbatasan kapasitas transmisi dan suplai daya reaktif seringkali membuat sistem tenaga beroperasi mendekati batas kestabilannya. Sebagai upaya proteksi terakhir, pelepasan beban (load shedding) harus dilakukan secara terarah. Penelitian ini mengkaji strategi pelepasan beban berdasarkan margin daya reaktif dengan menggunakan sistem standar IEEE 39 Bus pada perangkat lunak ETAP, metode usulan disimulasikan pada skenario terputusnya saluran 21-22 dan dibandingkan dengan metode konvensional. Hasil simulasi menunjukkan bahwa pelepasan beban berdasarkan margin daya reaktif mampu memulihkan tegangan sistem ke batas aman (di atas 95%) dengan waktu pulih yang jauh lebih cepat, yaitu 7,11 detik, dibandingkan metode konvensional yang membutuhkan waktu 28 detik. Meskipun metode usulan memutus total beban sekitar 34,5% lebih besar dibandingkan metode konvensional, pendekatan ini menawarkan, pendekatan ini menawarkan distribusi pelepasan beban yang lebih terukur, proporsional, dan adaptif terhadap kerentanan tiap bus demi menjaga keandalan sistem kelistrikan secara keseluruhan.

The continuously increasing demand for electrical energy, along with limitations in transmission capacity and reactive power supply, often forces power systems to operate near their stability limits. As a last-resort protection measure, load shedding must be executed in a targeted manner. This study examines a load shedding strategy based on reactive power margin. Using the standard IEEE 39 Bus system in ETAP software, the proposed method is simulated under a line 21-22 outage scenario and compared with the conventional method. Simulation results indicate that load shedding based on reactive power margin is capable of restoring the system voltage to safe limits (above 95%) with a significantly faster recovery time of 7.11 seconds, compared to the conventional method which requires 28 seconds. Although the proposed method sheds approximately 34.5% more total load than the conventional approach, it offers a more measured, proportional, and adaptive load shedding distribution tailored to the vulnerability of each bus, thereby maintaining the overall reliability of the electrical system.
