Abstract

The government will continue to increase the use of new and renewable energy as a solution to meet electricity needs, one of which is the use of rooftop solar power plants. In this research, the location that will be planned to install rooftop PV solar system is the Udayana University Rusunawa Building. The produced energy will be able to meet the electrical energy need and as well as supporting the government programs in the utilization of new and renewable energy. The capacity of the rooftop PV solar system to be installed is determined based on the load profile of the Udayana University Rusunawa Building. Three different scenarios namely 20 kW, 15 kW and 10 kW PV solar systems have been simulated using a PV solar simulator. Results of the simulation scenarios then are compared to look at the differences among the produced energy.

Abstract

The installed PLTS capacity in Bali is currently still 3.44% of the target given by the General National Energy Plan (RUEN) of 108 MWp in 2025. The island of Bali has limited land availability so rooftop PLTS is a solution. The design of the rooftop PLTS was carried out on the roof of the Wisti Sabha Building at I Gusti Ngurah Rai International Airport. The research uses PVSyst simulation software while the investment feasibility method uses the Benefit-Cost Ratio (BCR), Net Present Value and discounted payback period (DPP) methods. Based on the simulation results, the rooftop PLTS capacity is 56.6 kWp with energy production of 98,009 kWh/year. The B-CR value obtained is 2.23, the net present value is IDR 707,436,838.55 and the DPP is 7 years, with a rooftop solar system life of 25 years.

Abstract

Analisis rugi daya pada Penyulang Bangli dilakukan untuk mengetahui perbanding an rugi daya pada jaringan distribusi setelah penempatan pembangkit tersebar jenis PLTS berkapasitas 1 MWp. Lokasi penempatan PLTS ditentukan berdasarkan analisis sensitivitas bus. Nilai sensitivitas bus(?)didapat dengan cara membandingkan nilai rugi daya pada sistem dengan total beban yang terhubung pada bus. Penelitian ini menggunakan simulasi aliran daya dengan metode aliran daya Newton-Raphson. Hasil penelitian menunjukkan bus TK 0041 memiliki sensitivitas terbesar dengan nilai ?= 0,178. Dari hasil simulasi aliran daya, penempatan PLTS 1MWp pada lokasi alternatif 1 menghasilkan rugi daya minimum pada Penyulang Bangli yaitu 103,1 kW atau 3,3% dari total suplai daya 3071 kW. Pemasangan PLTS dapat menurunkan rugi daya pada Penyulang Bangli sebesar 57 kW dari total rugi daya pada kondisi tanpa PLTS yaitu 160,1 kW. Bila dibandingkan dengan kondisi eksisting, penem patan PLTS pada lokasi alternatif 1 memiliki selisih rugi daya 7,3 kW lebih kecil dari total rugi daya yang dihasilkan kondisi eksisting sebesar 110,4kW.  DOI: 10.24843/MITE.1501.01

Abstract

The micro hydro power plant (PLTMH) in Banjar Dinas Mekar Sari, was built independently by community groups in 1980. With the use of traditional technology, the efficiency of PLTMH is low, so it is necessary to re-plan for PLTMH Banjar Dinas Mekar Sari to operate more optimally.. One of the most important factors in planning is financial / economic factors. This factor will be used to assess a plan whether it is feasible to build or not. The parameters used in determining economic factors are Net Present Value (NPV, Internal Rate of Return (IRR), Benefit to Cost Ratio (BCR), Life Cycle Cost (LCC), and Break Even Point (BEP). Economic feasibility analysis has been carried out. for planning PLTMH Banjar Dinas Mekar Sari obtained, BCR of 0.23 and -0.08 and NPV value of Rp.476,747,506 and -Rp.161,451,546 are positive when the discount rate is 10% and negative when the discount value is 12%, and the amount of the IRR value 1% and 0% do not exceed Indonesia's Expected Annual Rate of Return, which is 14.6%, and the amount of BEP units that must be sold to reach a cash flow point is Rp. 0 of 2,294,914.96 kWh, and the amount of payback period at This project is 2 years 2 months. So seen from the existing economic parameters, the design of PLTMH in Banjar Dinas Mekar Sari is not feasible from an economic point of view because the large profits obtained from the design of PLTMH Banjar Dinas Bembang Sari do not exceed the initial start. al cost (investment cost).

Abstract

Sistem suplai energi listrik Kampus Universitas Udayana Denpasar saat ini berasal dari Penyulang Panjer, yang dengan konfigurasi jaringan tipe radial sehingga probabilitas untuk mengalami pemadaman sangat tinggi.  Sehingga diperlukan adanya rekonfigurasi jaringan untuk meningkatkan indeks keandalan yang dimiliki. Rekonfigurasi dilakukan dengan merubah konfigurasi jaringan tipe radial menjadi konfigurasi jaringan tipe spindel dengan melibatkan penyulang terdekat Kampus Udayana Denpasar yaitu penyulang Sudirman. Rekonfigurasi jaringan dilakukan dengan 2 skenario. Untuk kondisi existing Penyulang Panjer memiliki nilai SAIFI sebesar 0,8284 kegagalan/tahun, SAIDI sebesar 2,7318 jam/tahun, dan EENS sebesar 9,2126 MWh/tahun. Untuk penyulang Sudirman memiliki SAIFI sebesar 0,7938 kegagalan/tahun, SAIDI sebesar 2,5776 jam/tahun, EENS sebesar 7,1313 MWh/tahun. Setelah dilakukan rekonfigurasi jaringan, pada rekonfigurasi skenario 1 diperoleh nilai SAIFI sebesar 0,8024 kegagalan/tahun, SAIDI sebesar 2,6045 jam/tahun, dan EENS sebesar 8,8790 MWh/tahun. Selanjutnya pada rekonfigurasi skenario 2 diperoleh nilai SAIFI sebesar 0,1358 kegagalan/tahun, SAIDI sebesar 0,4985 jam/tahun, dan EENS sebesar 1,2647 MWh/tahun. Sehingga dapat diketahui bahwa rekonfigurasi skenario 2 memiliki nilai indeks keandalan lebih baik dan memiliki jumlah energi yang tidak tersuplai lebih kecil dibandingkan dengan kondisi existing.

Abstract

Captain I Wayan Dipta stadium rooftop power plant is designed as an additional power supply to meet the stadium's electrical load needs. Roof plts design using 2 scenarios. Scenario 1 has a capacity of 83,300 Wp with a solar module of 238 units and a 2-unit inverter generating 112,321 kWh/year of energy and will supply the day load of transformers 2 and 3 stadiums of 35,470 kWh/year. Scenario 2 with a capacity of 156,800 Wp with a solar module of 448 units and 4 inverters generates 211,458 kWh/year of energy and will supply the day load of transformer 1 stadium at 100,919 kWh/year. Scenario 1 investment cost of Rp.1,178,760,000 with total income up to 25 years amounting to Rp.1,090,635,084 while in scenario 2 costs investment amounting to Rp.2,237,860,000 and income up to the 25th year amounting to Rp.3,126,761,273 in economic feasibility analysis using NPV, PI, and the DPP is only scenario 2 which can be said to be feasible because in the 25th year the income is greater than the investment, while in scenario 1 the income will be worth the same as the investment in the 29th year. This means the system in scenario 1 is not feasible because it has a DPP longer than the lifespan of the project.
