Abstract

Pemanfaatan pembangkit listrik energi terbarukan
saat ini masih perlu dikoneksikan dengan pembangkit listrik
energi fosil agar mampu memenuhi kebutuhan beban akibat
penumpukan energi listrik yang dihasilkan. Oleh karena itu,
perlu adanya perencanaan pembangkitan daya masing-masing
pembangkit listrik agar dapat memenuhi kebutuhan beban
yang dinamis setiap periodenya, yang disebut dengan dynamic
economic dispatch. Salah satu sistem pembangkit listrik di
Indonesia yang memiliki sistem pembangkit listrik energi fosil dan terbarukan adalah sistem pembangkit listrik di wilayah Sulawesi Utara dan Gorontalo dimana terdapat Hydrothermal Coordination yaitu koordinasi pembangkitan daya antara pembangkit listrik tenaga termal dengan pembangkit listrik tenaga air yang memiliki karakteristik yang berbeda-beda dalam menentukan pembangkitan dayanya dan pada sistem
pembangkit listrik di wilayah Sulawesi Utara dan Gorontalo
terdapat keunikan dimana sistem pembangkit listrik tenaga air tersebut menggunakan sistem cascaded hydropower. Oleh
karena itu, akan dilakukan simulasi dengan metode mixed
integer linear programming (MILP) untuk mengetahui daya
masing-masing pembangkit dan hasil variabel pada sistem
cascaded hydropower seperti volume dan pelepasan udara
(discharge) serta total biaya pembangkitan dengan beberapa
kasus, yaitu kontrak take or pay (TOP) pada PLTP dan PLTG,
dan kedua kasus TOP tersebut dilakukan pada kondisi dimana
semua PLTU wajib dioperasikan dan tidak wajib
dioperasikan, sehingga totalnya ada 4 kasus. Hasil akhir
menunjukkan bahwa biaya pembangkitan listrik termurah
dicapai pada kasus penerapan kontrak TOP pada PLTP saja,
sedangkan hasil daya total, debit total, dan volume reservoir akhir pada masing-masing PLTA pada sistem cascaded
hydropower tidak mengalami perubahan walaupun terdapat
perbedaan kasus, yang berubah hanya pola daya, debit, dan
volume reservoirnya saja.

The use of renewable energy power plants for now still needs to be connected to fossil energy power plants to be able to meet load needs due to fluctuations in the electrical energy
produced. Therefore, it is necessary to carry out power generation planning for each plant to meet the needs of dynamic loads in each period, which is called dynamic economic dispatch. One of the power generation systems in Indonesia that has a fossil energy and renewable energy
generation system is a power generation system in the North Sulawesi region where there is Hydrothermal Coordination which is the coordination of power generation between thermal plants such as coal, diesel, gas, geothermal and hydropower plants that have different characteristics in determining their power generation and in the power generation system in the North Sulawesi region there there is unique where the hydropower plants operating there use a
multi-level hydropower system or also called the cascaded hydropower system, coupled with other renewable energy plants such as mini hydro and solar power plants. Therefore,
simulations will be carried out using the MILP (Mixed Integer Linear Programming) method to determine the power of each plant and the variable results in the cascade hydropower system such as volume and water discharge (discharge) as well as the total cost of generation with
several cases, namely the application of TOP (Take or Pay) contract in geothermal power plants,in geothermal and gas power plants, and both TOP cases are carried out in the condition that the The coal-fired power plant is required to turn on all and is not required to be turned on, so
there are a total of 4 cases. The final results show that the cheapest power generation cost is achieved by the case of implementing the TOP contract on the geothermal powerplants only, while the total power output, total discharge, and final reservoir volume of each hydropower
plant in the cascade hydropower system did not change even though in each case there was a difference in the pattern of power, discharge, and reservoir volume in each period.
