Seiring dengan pertumbuhan penduduk dan ekonomi di daerah Kalimantan Selatan kebutuhan listrik menjadi semakin bertambah. Sistem kelistrikan Provinsi Kalimantan Selatan sebagian besar dipasok dari Sistem Barito, Sistem Barito merupakan sistem interkoneksi kelistrikan terbesar di Kalimantan Selatan dengan jaringan transmisi 150 kV dan 70 Kv. Sistem tenaga listrik yang baik selain memperhatikan sektor ekonomis dan keandalan, dibutuhkan juga sistem yang memperhatikan dampak terhadap lingkungan karena hal inilah optimasi sistem pembangkit listrik diperlukan untuk dilakukan penjadwalan agar optimal secara ekonomis dalam suatu operasi pembangkitan energi listrik. Pada penelitian ini akan dilakukan penjadwalan ekonomis dan emisi untuk pembangkit listrik hidro dan termal menggunakan bantuan perangkat lunak Matlab 2016. Pada penelitian didapatkan hasil dari simulasi Dragonfly Algorithm menunjukkan bahwa faktor pembobotan berpengaruh kepada biaya pembangkitan. Jika faktor pembobotan lebih diprioritaskan pada faktor ekonomis, maka biaya pembangkitan akan murah, namun memiliki nilai emisi yang tinggi, begitu pula sebaliknya. Kata kunci — Sistem Barito, Sistem tenaga listrik, Pembangkit Hidro dan pembangkit Termal, Dragonfly Algorithm.
ABSTRAKKebutuhan listrik di Kalimantan Selatan dan Tengah menjadi semakin bertambah dikarenakan meningkatnya jumlah penduduk dan ekonomi serta mahalnya biaya pembangkitan listrik. Tujuan penelitian ialah meminimalkan biaya pembangkitan termal dan memecahkan permasalahan ekonomi dan emisi. Penelitian menggunakan metode Dragonfly algortihm yang mengkaji tentang optimasi ekonomi dan emisi pada PLTU Asam-asam, Pulang Pisau dan PLTA Riam Kanan dengan membuat program dengan menginputkan Cost Function dan Emission Function. Didapatkan rata-rata biaya pembangkitan dan emisi dari tanggal 1 – 4 September 2020 yaitu pada kasus 1 biaya pembangkit sebesar Rp 335.855.120 dan emisi sebesar 628,6 ton, pada kasus 2 biaya pembangkit sebesar Rp 251.891.340 dan emisi sebesar 943 ton, pada kasus 3 biaya pembangkit sebesar Rp 167.935.460 dan emisi sebesar 1257,3ton. Faktor pembobotan akan mempengaruhi biaya pembangkitan dan emisi yang dihasilkan.Kata kunci: Pembangkit Listrik, Dragonfly algortihm, Faktor Pembobotan ABSTRACTThe demand for electricity in South and Central Kalimantan is increasing due to the increasing population and economy as well as the high cost of generating electricity. The research objective is to minimize the cost of thermal generation and solve economic and emission problems. This research uses the Dragonfly algorithm method which examines the economic optimization and emissions at LTU Asam-Asam, Pulang Pisau and PLTA Riam Kanan by making a program by inputting Cost Function and Emission Function. Obtained the average cost of generation and emissions from September 1 - 4 2020, namely in case 1 the generator cost is IDR 335,855,120 and the emission is 628.6 tons, in case 2 the generator cost is IDR 251,891,340 and the emission is 943 tons, in case 3 the cost of the generator is Rp. 167,935,460 and the emission is 1257.3 tonnes. The weighting factor will affect the cost of generation and the resulting emissions.Keywords: Power Plant, Dragonfly algorithm, Weighting Factor
Electricity is one of the energies required by daily living since the greater demand for electricity increases greenhouse emissions that create emission gases resulting in global climate change. The main portion of the output cost is fuel's cost to manufacture electrical energy in thermal turbines. The use of electrical energy is currently rising increasingly following the increasing population. The research aims to optimize hydro generation to minimize thermal generation expense and address economic problems and pollution from shipping. With 2016b using Matlab applications and the lambda iteration process, the analysis method uses the Dragonfly Algorithm method. The analysis found that the average cost of fuel consumption provided by the Dragonfly Algorithm method was IDR 151,164,418 per day with an emission of 917.40 tons per day, based on the simulation results the Dragonfly Algorithm in testing by considering the emission of 5 practical steps. Meanwhile, with the emission of 918,044 tonnes per day, the average cost of fuel consumption produced by the Lambda Iteration method is IDR 151,202,209 per day. Test results can enhance the fuel consumption cost of IDR 37,791 and emissions of 0.641 tons with the Dragonfly Algorithm process.
