Peningkatan Available Transfer Capability Mengggunakan Unified Power Flow Controller

Abstract

Available Transfer Capability (ATC) adalah kemampuan transfer yang masih mungkin bisa dilakukan pada sistem tenaga listrik. Pemasangan perangkat FACTS, yaitu Unified Power Flow Controller (UPFC) dilakukan untuk meningkatkan nilai ATC. UPFC akan mengontrol injeksi daya reaktif dan mengontrol tegangan pada saluran transmisi yang dipasangi UPFC sehingga akan merubah aliran daya pada sistem tenaga listrik. Melalui analisis optimal power flow pada Sistem IEEE 14 bus, variabel-variabel kontrol akan diinjeksikan dari UPFC ke aliran daya Sistem IEEE 14 bus. Setelah dipasang UPFC sistem mampu mencapai nilai load margin maksimal pada 0,1511 ketika UPFC dipasang di Saluran 2-5, dengan ATC yang dicapai adalah 35,38 MW.
