Abstract

Permintaan energi listrik yang meningkat menuntut sistem tenaga listrik yang andal dan berkelanjutan. Gangguan pada sistem dapat menyebabkan pemadaman yang berdampak pada kerugian finansial dan penurunan produktivitas. Penelitian ini menganalisis kenaikan beban dan penambahan unit pembangkit terhadap nilai LOLP dan LOLE, serta merencanakan penambahan pembangkit yang efektif. Sistem kelistrikan 150 kV dimodelkan dengan total kapasitas terpasang 450 MW dan beban puncak 121,64 MW. Dengan pertumbuhan beban 12% per tahun, penelitian ini mengkaji dampak peningkatan beban terhadap keandalan sistem dan mitigasi melalui penambahan pembangkit baru serta integrasi Battery Energy Storage System (BESS). Metode rekursif dan simulasi Monte Carlo digunakan untuk menghitung LOLP, sementara Multi Criteria Decision Analysis (MCDA) digunakan untuk menentukan pembangkit yang paling efisien berdasarkan kriteria teknologi, keandalan, ekonomi, dan kapasitas. Hasil menunjukkan bahwa penambahan pembangkit dan BESS menurunkan nilai LOLP dan LOLE, meningkatkan keandalan sistem, dan sesuai dengan standar LOLP di bawah 0,00274. Strategi ini juga mempertimbangkan bauran energi terbarukan untuk keberlanjutan dan pengurangan emisi karbon.

The increasing demand for electricity requires a reliable and sustainable power system. Disruptions in the system can lead to blackouts, resulting in financial losses and reduced productivity. This study analyzes the impact of load increase and the addition of generating units on the values of LOLP (Loss of Load Probability) and LOLE (Loss of Load Expectation), as well as plans for effective generator additions. The 150 kV electrical system is modeled with a total installed capacity of 450 MW and a peak load of 121.64 MW. With a 12% annual load growth, this study examines the impact of load increase on system reliability and mitigation through the addition of new generators and the integration of a Battery Energy Storage System (BESS). Recursive methods and Monte Carlo simulations are used to calculate LOLP, while Multi Criteria Decision Analysis (MCDA) is employed to determine the most efficient generator based on technological, reliability, economic, and capacity criteria. The results show that the addition of generators and BESS reduces LOLP and LOLE values, enhances system reliability, and meets the LOLP standard below 0.00274. This strategy also considers a renewable energy mix for sustainability and carbon emission reduction.
