Abstract

Penelitian ini memprediksi kebutuhan listrik di Kabupaten Berau untuk 2025-2027 menggunakan regresi linear sederhana. Analisis data 2019-2024 menunjukkan tren pertumbuhan jumlah pelanggan dan daya tersambung yang konsisten. Model regresi memperkirakan kenaikan pelanggan sebesar 464,96 per bulan dan daya tersambung bertambah 1,04 MVA tiap bulan. Validasi menggunakan Mean Absolute Percentage Error (MAPE) menunjukkan tingkat kesalahan rendah, yaitu 0,6% untuk pelanggan listrik dan 3,7% untuk daya tersambung. Hasil peramalan memproyeksikan peningkatan pelanggan dari 89.331 pada 2024 menjadi 105.908 pada 2027, serta daya tersambung dari 183,90 MVA menjadi 207,57 MVA. Untuk menghadapi lonjakan permintaan, PT PLN (Persero) perlu meningkatkan infrastruktur serta menyediakan cadangan daya sebesar 13,10 MVA guna menjaga stabilitas pasokan listrik.

Abstract

Power flow analysis is essential, especially in electrical network systems, to determine the power capacity of an electrical energy system that has reached its specified limits. A power flow study is an analysis of electrical power flow within an electrical system. The research method employs the IEEE power flow method with a modified 26-bus system, analyzing power losses and voltage drops at each busbar in the circuit using the Newton-Raphson method and MATLAB R2017a software. This study aims to analyze the power flow values, power losses, and voltage drops in a modified IEEE 26-bus system using MATLAB software with the Newton-Raphson method. The results of the discussion and simulation show that the total active power and reactive power are 126.3 MW and 637 MVR, respectively, and the active power and reactive power of the generator are 1292.715 MW and 677.251 MVAR, respectively. The largest voltage drop occurs on line 16 to 17 with a voltage drop of 10.04%, and the lowest on line 17 to 21 with a voltage drop of -8.29%. According to SPLN standards, the voltage drop has a tolerance of +5% and a minimum of -10%. Therefore, it can be concluded that the analysis of the modified 26-bus IEEE power system does not comply with PLN standards, specifically on line 16 to 17. The simulation results show the largest active power loss of 6,221 MW and reactive power loss of 25,132 MVAR. .
