Abstract

The Saba feeder is one of the feeders located in the PLN working area of the East Bali Area,which is located around the villages of Saba, Blahbatuh and Blangsinga in the district of Gianyar.This feeder has 75 transformers with a capacity of 25-500 kVA that are connected by SUTM,SKUTM, MVTIC and ground cable lines. The reliability of the system in the Saba Feeder in thecondition before being reconfigured, with a SAIFI value of 3.02 interruptions in one year, the SAIDIvalue is 9.28 hours per year, while for the CAIDI value is 3.24 hours per one time, which is notcaused by maintenance. PT. PLN Persero regulated in SPLN No. 59 of 1985 and the target of PT.PLN PERSERO to achieve WCC or World Class Company standards, namely the value of SAIFI 3times interruption in one year, SAIDI 3 hours of interruption in one year and CAIDI value of amaximum of 3 hours of non-availability of electricity to customers. So the value of SAIFI PenyabaSaba before reconfiguration is in accordance with PLN standards, while the value of SAIDI andCAIDI Penyaba Saba conditions before reconfiguration is still outside the PLN standard to achieveWCC. Therefore, a network reconfiguration was done to improve the SAIDI and CAIDI values in theSaba Feeder to conform to SPLN No.59 of 1985. After the network reconfiguration of the Sabafeeder, changes in the SAIFI value, SAIDI and CAIDI on the Saba Feeder could improve, with theSAIFI value namely 2.73 disturbances per year, SAIDI value of 2.98 hours per year and CAIDIvalue of 1.08 hours per customer, so the reliability value in the Saba Feeder can be said to bereliable because it is in accordance with SPLN No. 59 of 1985.

Abstract

The rooftop on-grid PLTS system is commonly used by people from the household,commercial, to industrial sectors to reduce electricity bills from PLN. Based on PERMEN ESDM49 of 2018, the export value of electrical energy to the PLN electricity grid is 65%, and if energyexports are greater than energy bills, the rest will be stored and accumulated in the followingmonth. This is only valid for a maximum of 3 months, in the 4th month the remaining energyexport savings will be eliminated. Determining the right PLTS capacity makes the contribution ofPLTS in making bill savings more optimal. The office of BAPPEDA LITBANG Probolinggo Citywas used as the research location. The PLTS Scenario 1 design uses a capacity according tothe energy needs of the office, which is 21.6 kWp, and the PLTS Scenario 2 capacity is greaterthan the office energy requirement of 32.4 kWp. Based on the investment feasibility analysisusing the NPV, PI, and DPP methods, it shows that the Scenario 1 and Scenario 2 PLTSdesigns are feasible to run. PLTS Scenario 1 and Scenario 2 investment is Rp. 267,000,000and Rp. 395.85 million, respectively. The benefit of saving bills for 30 years of PLTS operation,in Scenario 1 is Rp. 406,863,069 or 152% of the total investment, while Scenario 2 is Rp.595,619,904 or 150% of the total investment.

Abstract

Dalam penulisan ini dibahas tentang aplikasi teori himpunan Fuzzy untuk menyelesaikan penempatan optimal dan kapasitas kapasitor bank pada penyulang distribusi. Ada beberapa penyulang yang mempunyai kualitas rendah pada profil tegangannya, disebabkan karena adanya beban-beban induktif yang dipergunakan oleh konsumen. Sebagai contoh penyulang-penyulang yang melayani daerah-daerah turis yang baru seperti di kabupaten Tabanan (penyulang Penebel) dan daerah kabupaten Buleleng (penyulang Menjangan). Untuk mengatasi masalah tersebut, dapat dilakukan dengan memasang kapasitor bank untuk mengkompensasi beban-beban induktif. Optimal placement and sizing of capacitor bank on the feeders of Penebel and Menjangan can be calculated based on a combination of maximum sensitivities selection, Fuzzy theorem, and local variations algorithm. Kesimpulan menunjukkan bahwa dengan mengaplikasikan metode ini untuk penyulang-penyulang Penebel dan Menjangan dapat memperbaiki profil tegangannya, sehingga tidak ada bus-bus pada kedua penyulang tersebut yang tegangannya melanggar batas-batas yang diijinkan. Demikian juga penghematan biaya tahunan cukup signifikan, yaitu sebesar 3043.94 USD untuk penyulang Penebel dan 2327.16 USD untuk penyulang.
