Abstract

Sistem kelistrikan Sulbagsel (Sulawesi Bagian Selatan) memiliki berbagai pembangkit dengan kapasitas daya terpasang total sebesar 2.473 MW dengan persentase Variable Renewable Energy (VRE) sebesar 33,4% dan beban puncak sistem mencapai 1.853,6 MW dengan cadangan daya sebesar 624,4 MW. Pada triwulan empat tahun 2023, terjadi El Nino yang berdampak pada PLTA dan pembangkit VRE sehingga sistem kelistrikan Sulbagsel mengalami defisit daya hingga 850 MW. Penyelesaian masalah defisit dan keandalan dapat dilakukan dengan banyak cara seperti membangun penambahan pembangkit, mengoptimalkan pola operasi, pengelolaan beban, penjadwalan pembangkit yang efektif, interkoneksi dengan sub sistem lain, kerjasama dengan IPP (Independent Power Producer) dan mengimplementasikan ESS (Energy Storage System). Berdasarkan RUPTL 2021-2030, sistem Sulbagsel tidak memungkinkan ditambah pembangkit EBT atau VRE kecuali dengan skema battery firming atau ESS, sedangkan untuk pembangunan pembangkit berbasis fosil telah dibatasi oleh pemerintah. Salah satu mitigasi yang dapat dilakukan PLN adalah mengevaluasi penerapan ESS pada sistem Sulbagsel. Pemilihan ESS pada sistem kelistrikan Sulbagsel dengan metode AHP-TOPSIS (Analytical Hierarchy Process - Technique for Order of Preference by Similarity to Ideal Solution) menjadi pilihan karena metode ini memiliki kelebihan dalam kompleksitas evaluasi dengan mempertimbangkan banyak kriteria yang komperehensif, analisis pembobotan yang menentukan akurasi dan pemilihan solusi yang optimal. Hasil penelitian menunjukkan bahwa alternatif ESS terbaik untuk diimplementasikan pada sistem kelistrikan Sulbagsel adalah PHES (Pumped Hydro Energy Storage) dengan nilai preferensi 0,6551, BESS (Battery Energy Storage System) menjadi peringkat kedua dengan nilai preferensi 0,4041 dan HESS (Hydrogen Energy Storage System) menjadi peringkat ketiga dengan nilai preferensi 0,2243.

The South Sulawesi electricity system comprises a number of power plants, with an aggregate installed power capacity of 2,473 MW which, 33.4% is derived from Variable Renewable Energy (VRE), while the system peak load is 1,853.6 MW, with a power reserve of 624.4 MW. In the fourth quarter of 2023, the occurrence of El Niño had an impact on both hydropower and VRE plants, resulting in a deficit of up to 850 MW in the South Sulawesi electricity system. The resolution of deficit and reliability issues can be achieved through a number of avenues, including the construction of supplementary power facilities, the optimisation of operational patterns, the implementation of load management strategies, the effective scheduling of plant operations, the interconnection with other sub-systems, the collaboration with IPPs (Independent Power Producers) and the deployment of ESS (Energy Storage Systems). In accordance with the RUPTL 2021-2030, the South Sulawesi system does not permit the incorporation of renewable or VRE plants, except in conjunction with battery firming or ESS schemes. Furthermore, the construction of fossil-based plants has been subject to constraints imposed by the government. One potential mitigation strategy for PLN is to assess the feasibility of integrating ESS into the South Sulawesi system. The selection of ESS in the South Sulawesi electricity system using the AHP-TOPSIS (Analytical Hierarchy Process - Technique for Order of Preference by Similarity to Ideal Solution) method is a viable option due to the method's ability to evaluate complex scenarios by considering a multitude of comprehensive criteria, conducting weighting analyses to determine accuracy, and identifying optimal solutions. The results demonstrate that the optimal ESS alternative for implementation in the South Sulawesi electricity system is PHES (Pumped Hydro Energy Storage) with a preference value of 0.6551, BESS (Battery Energy Storage System) is the second-ranked alternative with a preference value of 0.4041, and HESS (Hydrogen Energy Storage System) is the third-ranked alternative with a preference value of 0.2243.
