Abstract

Berdasarkan hasil penelitian, peningkatan kebutuhan daya pada Sistem Kelistrikan Sulawesi Bagian Selatan menyebabkan jaringan transmisi beroperasi mendekati batas kemampuan teknisnya. Kondisi ini menurunkan margin keamanan operasi, terutama ketika terjadi kontingensi yang mengubah distribusi aliran daya. Hasil screening kontingensi N-1 dan N-2 menunjukkan bahwa kontingensi N-2 saluran Pamona–Poso 1 dan Pamona–Poso 2 merupakan kondisi paling kritis karena membatasi transfer daya koridor Sulsel–Sulbar, dengan saluran Polman–Bakaru sebagai elemen pembatas utama. Simulasi transfer ramp menunjukkan bahwa pada kondisi tanpa SSSC, kemampuan transfer daya maksimum hanya mencapai 8,085 MW dengan mempertimbangkan batas pembebanan saluran 100%, rentang tegangan 0,90–1,05 pu, batas kemampuan pembangkit pengirim, dan konvergensi aliran daya. Setelah optimasi menggunakan Algoritma (Particle Swarm Optimization), pemasangan SSSC mampu meningkatkan kapabilitas transfer daya pada seluruh skenario. Lokasi SSSC paling optimal diperoleh pada saluran Parepare–Polman dengan transfer daya maksimum 24 MW, lebih tinggi dibandingkan skema Polman–Bakaru sebesar 17,45 MW. Kapasitas optimum pada Parepare–Polman adalah Xeff SSSC dengan mengurangi reaktansi sebesar -7,416 Ω. Nilai negatif menunjukkan kompensasi kapasitif yang menurunkan reaktansi efektif saluran, meningkatkan aliran daya Parepare–Polman, dan memperbesar transfer daya koridor Sulsel–Sulbar. Dengan demikian, SSSC efektif sebagai perangkat pengendali aliran daya seri untuk meningkatkan fleksibilitas operasi dan keamanan sistem pada kontingensi kritis N-2. Hasil ini juga menunjukkan bahwa pemilihan lokasi berbasis optimasi lebih tepat dibandingkan penempatan langsung pada saluran yang mengalami pembebanan kritis.

Based on the research results, the increasing power demand in the Southern Sulawesi Power System has caused the transmission network to operate closer to its technical limits. This condition reduces the operational security margin, particularly under contingency events that alter the power flow distribution. The N-1 and N-2 contingency screening results indicate that the N-2 contingency of the Pamona–Poso 1 and Pamona–Poso 2 transmission lines represents the most critical condition, as it limits the power transfer capability of the South Sulawesi–West Sulawesi corridor, with the Polman–Bakaru line acting as the main limiting element. The transfer ramp simulation shows that, under the condition without SSSC, the maximum power transfer capability reaches only 8.085 MW, considering a maximum line loading limit of 100%, a voltage range of 0.90–1.05 pu, the sending-end generator capability limits, and power flow convergence. After optimization using Particle Swarm Optimization, SSSC installation improves the power transfer capability in all scenarios. The optimal SSSC placement is obtained on the Parepare–Polman line, producing a maximum power transfer of 24 MW, which is higher than the Polman–Bakaru scheme at 17,45 MW. The optimum SSSC capacity on the Parepare–Polman line is Xeff SSSC=-7.416 Ω. The negative value indicates capacitive compensation, which reduces the effective line reactance, increases the power flow on the Parepare–Polman line, and enhances the transfer capability of the South Sulawesi–West Sulawesi corridor. Therefore, SSSC is effective as a series power flow controller for improving operational flexibility and system security under critical N-2 contingency conditions. The results also indicate that optimization-based placement is more appropriate than direct placement on the critically loaded transmission line.
