Abstract

Bagian terpenting dalam sistem Pembangkit Listrik Tenaga Surya adalah elemen penyimpanan. Sebuah baterai kimia atau super capsitor digunakan sebagai penyimpanan dan mengumpulkan fluktuasi energi. Akan tetapi baterai akan cepat habis seiring dengan penggunaan sehingga perlu diisi atau charging. Untuk charging pada baterai memerlukan arangkaian konverter yang adapat mengatur arah aliran adaya yang amengalir untuk amengisi atau amenggunakan baterai. Bidirectional converter adapatabekerja pada aduaamode, yaitu amode buck (Charging) dan amode boost (discharging) digunakan sebagai kontrol baterai pada PLTS. Mode charging yaitu ketika PV menghasilkan daya yang tinggi maka converter buck akan menurunkan tegangan untuk pengisian baterai dan menyuplai kebutuhan beban. Mode discharging dimana ketika PV tidak dapat memenuhi kebutuhan beban dimana baterai akan melepas energinya ke beban. Pada hasil perakitan Bidirectional Converter terdapat setting point yaitu pada saat tegangan PV diatas 14,9 v maka bidirectional converter akan bekerja dalam mode buck, dan apabila tegangan PV kurang dari 14,9 maka bidirectional converter akan bekerja dalam mode boost. Bidirectional converter ini mampu memberikan output arus charging 2,0A dan tegangan output 13,3V. Pada hasil pengujian menunjukkan bahwa bidirectional converter dapat bekerja dalam kondisi charging maupun discharging.

Abstract

This study analyzes the impact of integrating a 100 MW Solar Power Plant (PLTS) (4×25 MW) on the frequency stability of the power system in the 150 kV transmission network in Bali. Simulations were conducted using DIgSILENT PowerFactory software employing Load Flow and RMS Simulation methods, covering disturbance scenarios such as load increases up to 60%, generator outages (Gilimanuk and Pemaron), and the effect of system protection settings. Results show that without proper protection settings, the integration of PLTS leads to a frequency drop below the minimum threshold (47.76 Hz) and a high Rate of Change of Frequency (ROCOF) (-1.21 Hz/s), which poses a risk of system disconnection. After configuring protective relays (underfrequency, undervoltage, and df/dt), the system stability improved; frequency was maintained within the 48–52 Hz range, and ROCOF decreased below -0.5 Hz/s. Therefore, large-scale PLTS integration can be safely implemented without compromising system stability, provided that appropriate protection configurations are in place. This research supports the implementation of clean energy in Bali and serves as a reference for integrating renewable energy sources into existing power systems.
