RSBM feeder is one of the feeders sourced from transformer 2 of the Amlapura Substation. This feeder is a radial type 20 kV distribution network configuration with 133 distribution transformers with a total power of 5.428 kVA and a load of 144 amperes. The lowest voltage condition in RSBM feeders has reached 18,608 kV or a voltage drop of 6.96%. To overcome the voltage drop and power loss in RSBM feeders, it is necessary to reconfigure the network. Network reconfiguration is done by planning a new feeder (Rendang feeder). Analysis of power loss and voltage drop using the help of ETAP software. Based on studies that have been done, before the network reconfiguration is obtained the percentage of voltage drop is 6,98% and the power loss is 5,68%. After being reconfigured with a new feeder plan (Rendang feeder), it showed good results, ie the percentage of voltage drop dropped to 2.09% and the power loss dropped to 3.20%. Whereas the Rendang feeder showed good results with the percentage of voltage drop of 2.78% and the power loss of 3.47%. Based on load forecasting for the next 5 years on RSBM feeders the voltage drop and power loss are still according to the standard. Whereas the Rendang feeder occurs a voltage drop and a power loss that is not up to standard in 2023, namely a voltage drop of 5.20% and a power loss of 5.07%. So that for the Rendang feeder in 2023 it is necessary to break the load or reconfigure the feeder again.

Solar Power Plant (PLTS) is a technology to convert solar energy into electricity. RUEN statesthat the potential for solar electricity in Indonesia is estimated at 207.89 GW and it has beendetermined that the national PLTS capacity target in 2025 is 6.5 GW and continues to increaseto 45 GW in 2050. One of the efforts that can be made to achieve this target is to usegovernment buildings as a place to install PLTS. This study was conducted to find out howmuch potential electrical energy is generated on the rooftop PLTS of the North TapanuliRegent's office which has a roof slope of 52.70. It was found that the PLTS of the NorthTapanuli Regent's office has the potential to generate 39.6 kWp of electrical power. Thesimulation shows the energy data produced by the PV system is 45,646 kWh in one year andhas a role in supplying electrical energy up to 52.9%. So the total of the PV system with Gridelectrical energy supplied to the load is 86,233 kWh/year.

In the RUPTL PT PLN Years 2017 untill 2026, the goverment aim to reach 5000 MW of PV plant potential in 2025. But, until November 2016, the number of PV plant in Indonesia is around 11 MW. To reach the 5000 MW target, many approach must be use. One of the approach is install PV plant on goverment buildings. Pusat Pemerintahan Kabupaten Badung (Puspem Badung) is a goverment buildings complex which located in Badung Regency, Bali is one of the goverment building that can be use for this approach. This paper aim to know the potency of electrical power dan electrical energy produced by Puspem Badung if the PV plant installed on the north, east, west, and south side of the roof. Electrical energy produced by PV plant is simulated by using System Advisor Model (SAM). From the simulation results, north side of the roof can produce energy of 1.847.361 kWh/year. From the analysis, the total energy that can be produced by PV plant is 6.169.092 kWh/year. This amount can supply Puspem Badung energy need by 124,72 %.

Increasing energy demand with limited resources is an obstacle in supplying demand for electrical energy sources at this time. The solution to this problem becomes essential due to the planning of excessive energy supply, as well as planning that does not meet the energy demand will cause new problems on the side of energy production. Therefore accurate energy consumption forecasting is very important. In this study, the projected use of energy in the processing industry sector in Bali uses LEAP software using a database from 2015 to 2018. The use of fuels in the processing industry in Bali according to modeling results will continue to increase until 2050. This increase due to an increase in population resulting in increased demand for processing industry products so that the production of processing industries has increased which directly increases fuel consumption. This increase in production is also due to increased purchasing power, this is shown from the increase in per capita GRDP of Bali province which has increased until 2050. GRDP of the processing industry according to modeling results has increased until 2050 this is in accordance with the energy needs of the processing industry , where an increase in the production of the processing industry will also result in an increase in the GRDP of the processing industry

Distributed Generation (DG) merupakan pembangkit listrik skala kecil yang umumnya terhubung langsung dengan jaringan distribusi dan dekat dengan pusat beban. Penyulang Payogan merupakan salah satu penyulang yang dekat dengan potensi DG yaitu berupa Pembangkit Listrik Tenaga Mikro Hidro (PLTMH) sungai Ayung yang berada di Wilayah Ubud. Penelitian ini tentang optimasi interkoneksi Distributed Generation ke penyulang Payogan. Tujuan penelitian ini adalah untuk mengetahui pengaruh interkoneksi Distributed Generation pada jaringan distribusi tenaga listrik dan untuk memperbaiki drop tegangan penyulang Payogan menggunakan load flow analysis. Berdasarkan penelitian yang telah dilakukan diperoleh hasil sebelum pemasangan Distributed Generation drop tegangan pada bus 109 sebesar 1,80 V, bus 111 sebesar 1,49 V, bus 113 sebesar 2,56 V dan bus 115 sebesar 2,40 V. Setelah PLTMH dioptimasi menggunakan metode Genetic Algorithms diperoleh hasil pada Bus 107. Dengan kapasitas PLTMH sebesar 2,34 MW berhasil memperbaiki tegangan penyulang Payogan sebesar 0,05%, sehingga drop tengangan pada bus 109 menjadi 1,76 V, bus 111 menjadi 1,45 V, bus 113 menjadi 2,49 V dan bus 115 menjadi 2,35 V.Kata Kunci:Drop Tegangan, Load Flow Analysis, Genetic Algorithms

Rugi energi terjadi jika jumlah energi yang disalurkan tidak sama dengan energi yang diterima oleh konsumen tenaga listrik. Rugi energi merupakan salah satu parameter kualitas jaringan listrik. Rugi energi yang tinggi pada jaringan dapat mengakibatkan pula rugi tegangan yang tinggi, sehingga tegangan pelayanan menjadi turun. Menurut SPLN 1, 1995 tegangan pelayanan maksimum adalah +5 % dan minimun -10 % terhadap tegangan nominal. Salah satu cara untuk menurunkan rugi energi yang dilaksanakan oleh PT PLN (Persero) adalah dengan mengganti tap connector tiap sambungan jaringan tegangan rendah dengan connector type press. Penelitian ini menganalisis besarnya rugi energi yang terjadi sebelum penggantian dan setelah penggantian connector. Hasil analisis menunjukkan bahwa dengan dilaksanakannya penggantian tap connector, maka rugi energi pada jaringan tegangan rendah yang terhubung pada transformator DS105 dapat diturunkan sebesar 63,4327 Wh atau sebesar 23,2448%. Dengan kata lain, rugi energi dapat diturunkan dari 272,8896 Wh sebelum penggatian tap connector menjadi 209,4569 Wh setelah penggantian tap connector.

Salah satu Distributed Generation (DG) yang beroperasi di Bali adalah Pembangkit Listrik Tenaga Minihidro (PLTM) yang yang berada di Desa Sambangan, Kabupaten Buleleng. PLTM tersebut terhubung dengan salah satu penyulang di daerah Buleleng yaitu Penyulang Panji. PLTM tersebut memiliki kapasitas pembangkit sebesar 2 x 1,15 MW yang mampu membantu suplai daya listrik ke Penyulang Panji selain pasokan daya listrik dari Gardu Induk Pemaron. PLTM mampu memberikan pengaruh penurunan rugi daya (losses), namun penempatan titik interkoneksi yang kurang tepat dapat menyebabkan penurunan rugi-rugi daya yang kurang maksimal. Pada Penelitian ini dilakukan optimasi penempatan titik interkoneksi PLTM dengan metode Genetic Algorithm (GA) dan didapatkan lokasi terbaik titik interkoneksi PLTM berada pada bus 70 dengan rugi-rugi daya total sebesar 31 kW. Interkoneksi PLTM pada bus tersebut dapat menurunkan rugi-rugi daya aktif sebesar 5 kW dari total rugi-rugi daya awal saat kondisi eksisting yaitu pada bus 35 sebesar 36 kW menjadi 31 kW.

Stabiltas merupakan kemampuan sistem untuk menjaga kondisi operasi seimbang dan kembali kekondisi operasi normal ketika terjadi gangguan. Penerapan power system stabilizer pada sistem tenaga mampu memberikan sinyal respon yang cepat atas berbagai kondisi gangguan dan mengupayakan tidak meluasnya jangkauan gangguan. Dalam mendesign power system stabilizer menggunakan robust fuzzy logic, menggunakan satu sinyal input yaitu kecepatan deviasi rotor. Hasil simulasinya dibandingkan dengan metode fuzzy logic dan kovensional. Studi simulasi menunjukan, design power system stabilizer menggunakan robust fuzzy logic memiliki nilai sinyal peak time dan settling time relatif kecil dibandingkan dengan metode fuzzy logic dan konvensional.
