Abstract
Pembangkit listrik tenaga biomassa (PLTBm) dapat diperoleh dari residu sawit dan karet seperti yang dikembangkan di Pulau Nias. Biomassa adalah pembangkit listrik yang cocok disambungkan pada sistem tegangan menengah. PLTBm dapat menjadi pembangkit listrik swasta yang memungkinkan adanya perubahan aliran daya pada jaringan. Akibatnya, harga listrik menjadi berbeda untuk setiap konsumen. Di masa depan, utility dapat menetapkan harga listrik yang berbeda bergantung pada kontribusi daya masing-masing pembangkit dan harga pembangkitan. Dibutuhkan metode untuk mengetahui aliran daya dari suatu pembangkit ke beberapa beban atau sebaliknya. Pada Tugas Akhir ini dilakukan analisis metode power flow tracing pembangkit listrik tenaga biomassa menggunakan plant IEEE 30 bus modifikasi. Data PLTBm didapat dari real plant potensi biomassa di Pulau Nias yang dimodelkan dengan generator. Kemudian disambungkan pada sistem IEEE 30 bus yang dimodifikasi. Pada sistem IEEE 30 bus terdapat bus tegangan tinggi, sehingga perlu adanya modifikasi menjadi tegangan menengah. Dengan power flow tracing dapat diketahui aliran daya dari beberapa pembangkit ke beberapa beban beserta losses yang terjadi. Berdasarkan hasil analisis didapatkan BPP PLTBm karet sebesar Rp 982/kWh dan sawit Rp 1.832/kWh. Harga listrik dari grid sebesar Rp 1.561/kWh saat WBP dan Rp 1.1115/kWh saat LWBP. Harga jual listrik ditentukan dengan persentase kontribusi daya dan losses masing-masing pembangkit dikalikan dengan harga listrik per kWh. Kemudian ditambah keuntungan utility 10%. Semakin besar nilai losses, harga jual listrik yang dikenakan kepada konsumen juga semakin mahal.

Biomass power plants (PLTBm) can be obtained from oil and rubber residues like developed on Nias Island. Biomass is a suitable power plant connected to a medium voltage system. PLTBm can be a private power plant that changes power flow on the network. As a result, the price of electricity is different for each consumer. In the future, consumers can choose to subscribe electricity from certain plants that are profitable in terms of price and power quality. A method is needed to find out the power flow from a generator to several load, as well as power extracted from some generator to a load. In this Final Project, an analysis of the power flow tracing of the biomass power plant using modified IEEE 30 bus plant. Biomass power plant data was obtained from the real plant on Nias Island which was modeled with generator. Then connected to the modified IEEE 30 bus system. In the IEEE 30 bus system there are high voltage bus, so it needs to be modified into a medium voltage. With the power flow tracing, it can be seen that the power flow from several plants to several loads and losses that occur. Based on the results of the analysis, the price of biomass power plant from rubber is IDR 982 / kWh and from palm oil is IDR 1.832 / kWh. The price of electricity from the grid is IDR 1.561 / kWh at load peak time and IDR 1.1115 / kWh at outside of load peak time. The selling price of electricity is determined by the percentage of the contribution of each power plant multiplied by the price per kWh. The greater the value of losses, the selling price of electricity charged to consumers is also increasingly expensive.
