Abstract

Pemerintah Indonesia berkomitmen mencapai Net Zero Emission (NZE) tahun 2060 melalui peningkatan pemanfaatan energi baru terbarukan (EBT), termasuk pembangunan Pembangkit Listrik Tenaga Surya (PLTS) hingga 220 MW pada Sistem Kelistrikan Tambora. Peningkatan penetrasi PLTS berpotensi menurunkan inersia sistem dan menimbulkan ketidakstabilan frekuensi akibat sifat pembangkit EBT yang intermiten. Penelitian ini bertujuan untuk menganalisis pengaruh integrasi PLTS serta penambahan Battery Energy Storage System (BESS) terhadap kestabilan frekuensi pada Sistem Tambora. Metodologi penelitian dilakukan dengan memodelkan Sistem Tambora dalam DIgSILENT PowerFactory 2024 melalui pembuatan Single Line Diagram dan validasi kondisi eksisting menggunakan analisis aliran daya. Setelah validasi, dilakukan simulasi RMS untuk mengevaluasi respons frekuensi ketika terjadi gangguan berupa pelepasan unit pembangkit. Studi dilakukan dengan membandingkan kondisi sistem sebelum dan sesudah integrasi PLTS, kemudian dianalisis kembali setelah penambahan BESS. Parameter utama yang digunakan untuk menilai kestabilan frekuensi adalah nilai frequency nadir dan Rate of Change of Frequency (RoCoF), yang menggambarkan kemampuan sistem dalam menahan dan memulihkan frekuensi setelah gangguan. Hasil yang diharapkan menunjukkan bahwa integrasi PLTS menyebabkan penurunan inersia yang berdampak pada memburuknya nilai nadir dan meningkatnya RoCoF, sementara penambahan BESS mampu memperbaiki kedua parameter tersebut melalui respons cepat terhadap ketidakseimbangan daya. Penelitian ini memberikan manfaat sebagai referensi teknis bagi operator sistem tenaga dalam pengelolaan integrasi PLTS dan BESS pada Sistem Tambora guna meningkatkan keandalan dan stabilitas jaringan listrik.

The Government of Indonesia has committed to achieving Net Zero Emission (NZE) by 2060 through a significant increase in renewable energy utilization, including the planned development of up to 220 MW of solar photovoltaic (PV) generation in the Tambora Power System. However, high PV penetration may reduce system inertia and introduce frequency instability due to the intermittent nature of renewable generation. This study aims to analyze the impact of PV integration and the addition of Battery Energy Storage Systems (BESS) on the frequency stability of the Tambora system. The methodology involves modeling the Tambora network in DIgSILENT PowerFactory 2024 by constructing the Single Line Diagram and validating the model using load flow analysis to match existing operating conditions. Following validation, RMS dynamic simulations are performed to evaluate frequency response under generator outage events. The analysis compares system conditions before and after PV integration, followed by further evaluation with the inclusion of BESS. Two key indicators, frequency nadir and Rate of Change of Frequency (RoCoF) are used to assess the system’s capability to withstand and recover from disturbances. A step-by-step simulation approach is applied to observe the dynamic influence of each technology on frequency stability. The expected results indicate that PV integration reduces system inertia, leading to a deeper frequency nadir and higher RoCoF, whereas the addition of BESS is anticipated to improve both indicators by providing fast active power support during disturbances. Overall, the combined use of PV and BESS is expected to significantly enhance the system’s ability to maintain stable frequency operation. This study provides meaningful technical insights for system operators in managing PV and BESS integration within the Tambora Power System to improve grid reliability and frequency stability.
