Abstract

Integrasi PLTS dan Battery Energy Storage System (BESS) pada sistem tenaga listrik dapat memengaruhi karakteristik stabilitas frekuensi, terutama pada sistem yang sebelumnya didominasi oleh pembangkit konvensional. Penelitian ini menganalisis pengaruh penambahan PLTS dan BESS terhadap stabilitas frekuensi Sistem Kelistrikan Ambon–Seram tahun 2033. Pemodelan dan simulasi dilakukan menggunakan DIgSILENT PowerFactory melalui analisis aliran daya dan simulasi stabilitas RMS. Skenario penelitian meliputi kondisi Beban Puncak Siang (BPS) dan Beban Puncak Malam (BPM) dengan tiga konfigurasi, yaitu sistem tanpa PLTS dan BESS, sistem dengan PLTS dan BESS tanpa plant model, serta sistem dengan PLTS dan BESS menggunakan plant model. Studi kasus gangguan yang dianalisis meliputi pembangkit lepas, beban lepas, dan kabel laut lepas. Hasil simulasi menunjukkan bahwa integrasi PLTS dan BESS masih dapat diterima dari sisi aliran daya karena profil tegangan dan pembebanan jaringan berada dalam batas operasi yang diizinkan. Pada simulasi dinamis, BESS tanpa plant model belum mampu meredam deviasi frekuensi secara optimal. Sebaliknya, BESS dengan plant model mampu memberikan respons daya aktif secara dinamis sehingga lebih efektif dalam menahan penurunan maupun kenaikan frekuensi. Gangguan kabel laut lepas menjadi kondisi paling kritis karena menyebabkan Sistem Ambon dan Sistem Seram terpisah. Efektivitas BESS lebih terlihat pada Sistem Ambon karena seluruh PLTS dan BESS ditempatkan di wilayah tersebut. Dengan demikian, efektivitas BESS dalam mendukung stabilitas frekuensi dipengaruhi oleh model kendali dinamis dan lokasi pemasangannya.

The integration of solar photovoltaic power plants (PLTS) and Battery Energy Storage Systems (BESS) into power systems may affect frequency stability characteristics, particularly in systems previously dominated by conventional generation. This study analyzes the impact of PLTS and BESS integration on the frequency stability of the Ambon–Seram power system in 2033. Modeling and simulation were carried out using DIgSILENT PowerFactory through load flow analysis and RMS stability simulation. The study scenarios include Daytime Peak Load (BPS) and Nighttime Peak Load (BPM) conditions with three configurations: the system without PLTS and BESS, the system with PLTS and BESS without a plant model, and the system with PLTS and BESS using a plant model. The disturbance cases analyzed include generator outage, load disconnection, and submarine cable outage. The simulation results show that the integration of PLTS and BESS is acceptable from the load flow perspective, as the voltage profile and network loading remain within the allowable operating limits. In the dynamic simulation, BESS without a plant model was not able to optimally mitigate frequency deviations. In contrast, BESS with a plant model was able to provide a dynamic active power response, making it more effective in reducing both frequency drops and frequency rises. The submarine cable outage represents the most critical condition because it separates the Ambon and Seram systems. The effectiveness of BESS is more apparent in the Ambon system because all PLTS and BESS units are installed in that area. Therefore, the effectiveness of BESS in supporting frequency stability is influenced by its dynamic control model and installation location.
