Abstract

Pembangkitan harus dijadwalkan dengan baik untuk menghindari ketidaksesuaian antara produksi dan konsumsi listrik. Dalam memenuhi kebutuhan listrik yang selalu berubah dalam 24 jam, dibutuhkan penjadwalan operasi pembangkit mana yang harus nyala (commit) dan mati (uncommit) pada tiap jam untuk mendapatkan kombinasi pembangkitan yang memenuhi pembebanan namun dengan biaya paling murah. Pada Tugas Akhir ini penjadwalan untuk generator dan Battery Energy Storage System (BESS). Sistem penyimpanan energi dapat memperbaiki saat sistem terjadi ketidakseimbangan daya karena energi dapat disimpan lalu diinjeksikan pada saat yang diinginkan. Sehingga perlu penjadwalan kapan baterai menginjeksikan (discharging) ke sistem dan kapan saatnya mengisi daya (charging). Selain daya aktif, sistem penyimpanan energi baterai dapat terjadi pertukaran daya reaktif. Tugas akhir ini dilakukan studi unit commitment dengan mempertimbangkan batasan-batasan pembangkit dan BESS menggunakan metode Mixed Integer Linear Programming (MILP) untuk mendapatkan kombinasi pembangkitan yang paling optimal.

Generation must be properly scheduled to avoid mismatches between electricity production and the load consumption. To meet the ever-changing electricity demand within 24 hours, it is necessary to schedule the operation of which plants must be on (commit) and off (uncommitted) every hour to get a combination of generation that meets the load but at the lowest cost. In this final project scheduling for generator and Battery Energy Storage System (BESS). Energy storage systems can correct when the system is power imbalanced because energy can be stored and then injected at the desired time. So it is necessary to schedule when the battery injects (discharging) into the system and when it is time to charge (charging). In addition to active power, battery energy storage systems can exchange reactive power. In this final project, a unit commitment study is carried out by considering the limitations of the generator and BESS using the Mixed Integer Linear Programming (MILP) method to obtain the most optimal combination of generation.
