Abstract

Dalam Rencana Usaha Penyediaan Tenaga Listrik (RUPTL) PT PLN 2021-2030 akan dibangun PLTS dengan kapasitas 5 MW di Pulau Bawean pada tahun 2024. Dalam instalasi sistem PV grid tied perlu diperhatikan pemilihan tempat dan kapasitas paling optimal untuk mengurangi losses sistem. Namun, implementasi PV grid tied berpotensi menghasilkan distorsi harmonik akibat penggunaan inverter. Penelitian tugas akhir ini berkontribusi dengan melakukan optimasi dengan Symbiotic Organism Search (SOS) untuk menentukan lokasi dan kapasitas optimum pemasangan PV di Pulau Bawean. Hasil yang diperoleh dilakukan assessment harmonisa secara simulasi menggunakan software ETAP Power Station untuk mengetahui dampaknya ke sistem. Simulasi akan dilakukan dengan memodelkan tiga manufaktur inverter yang dioperasikan pada faktor daya 1 dan 0,85. Penentuan kapasitas dan lokasi optimum PV diperoleh sebesar 300kW di Penyulang Kota serta 250kW dan 350kW di Penyulang Sangkapura. Hasil yang diperoleh mampu meningkatkan tegangan rata-rata sistem dari 94,9% menjadi 95,9% serta mengurangi rugi-rugi daya dari 187kW menjadi 169kW. Semakin tinggi iradiasi, THDi pada sistem semakin tinggi dan sebaliknya pada sisi saluran yang terhubung langsung ke inverter akan semakin rendah. Nilai THDi di sistem Bawean masih di bawah standar IEEE 519 2014 dengan nilai batas aman adalah 15% kecuali THDi pada saluran output inverter masih melebihi standar IEEE 519 2014 dengan batas 5%. THDv sistem memiliki nilai yang masih di bawah standar IEEE 519 2014 yaitu kurang dari 8% untuk tegangan rendah dan kurang dari 5% untuk tegangan menengah. Pengoperasian inverter dengan faktor daya 0,85 lebih baik dalam memperbaiki tegangan dan mengurangi rugi-rugi jaringan namun menghasilkan distorsi harmonik yang lebih besar daripada pengoperasian faktor daya 1.

When installing a grid-tied PV system, it is important to carefully select the most optimal location and capacity to minimize system losses. However, the implementation of grid-tied PV systems has the potential to introduce harmonic distortion due to the use of inverters. This final project research aims to contribute by optimizing the Symbiotic Organism Search (SOS) method to determine the ideal location and capacity for installing PV systems on Bawean Island. The results obtained were validated through a harmonic assessment simulation using the ETAP Power Station software, which helped determine the impact on the system. The simulation involved modeling three inverter manufacturers operating at power factors of 1 and 0.85. The optimum PV capacity and location were determined to be 300 kW in the Kota Feeder and 250 kW and 350 kW in the Sangkapura Feeder. Implementing these optimizations resulted in an increase in the average system voltage from 94.9% to 95.9% and a reduction in power losses from 187 kW to 169 kW. It was observed that higher solar irradiation levels increased the total harmonic distortion (THDi) in the system, while lower solar irradiation levels resulted in lower THDi on the side connected directly to the inverter. However, the THDi value in the Bawean system remained below the IEEE 519 2014 standard, which sets a safe limit of 15%, except for the THDi on the inverter output channel, which exceeded the standard's 5% limit. The total harmonic distortion of voltage (THDv) in the system was found to be below the IEEE 519 2014 standard, which sets the limits at less than 8% for low voltage and less than 5% for medium voltage. Operating the inverters at a power factor of 0.85 proved to be more effective in improving voltage and reducing network losses, but it also generated higher levels of harmonic distortion compared to operation at a power factor of 1.
