Abstract


Penelitian ini menunjukan studi tentang optimasi sistem tenaga listrik mempertimbangkan kestabilan transien. Pertambahan kebutuhan tenaga listrik yang tidak sebanding dengan pertambahan infrastruktur tenaga listrik menyebabkan sistem sistem beroperasi lebih dekat pada batas kestabilan. Pada sistem dengan biaya pembangkitan yang paling murah karena sudah meggunakan analisa aliran daya optimal, belum tentu ketika dilakukan pengujian kontingensi sistem tetap stabil. Studi ini menggabungkan analisa aliran daya optimal dan pengujian kestabilan transien. Pengujian menggunakan metode simulasi berbasis waktu dan pusat inersia. Generator dimuodelkan secara multimesin dan dilihat kurva ayunan sudut rotornya. Stabil atau tidaknya sistem dianalisa dari sudut rotor terhadap pusat beban. Metode yang digunakan adalah Oppositional Krill Herd Algorithm. Keluaran dari penelitian ini adalah biaya pembangkitan yang termurah dan secara preventif mencegah ketidakstabilan transien pada saat kontingensi tertentu.
