Abstract

Operasi sistem kelistrikan di Sulawesi dilaksanakan dengan memprioritaskan keandalan, mutu, dan efisiensi biaya. Salah satu indikator penting dalam hal ini adalah susut energi listrik. Di Makassar dan wilayah sekitarnya yang merupakan pusat konsumsi energi diperkirakan akan terjadi peningkatan beban yang signifikan. Namun, terdapat tantangan besar terkait susut daya karena adanya jarak yang jauh antara lokasi pembangkit listrik skala besar dan pusat beban sehingga berpotensi menyebabkan susut yang besar akibat jarak transmisi yang jauh. Untuk meminimalisir susut daya dalam sistem kelistrikan, terdapat dua metode yang digunakan yaitu incremental losses dan optimal power flow. Analisis incremental losses bertujuan untuk mengevaluasi dan mengatur ulang distribusi pembangkitan di seluruh sistem dengan mempertimbangkan dampak perubahan daya pada tiap bus pembangkit terhadap susut daya secara keseluruhan. Di sisi lain, metode optimal power flow berfokus pada optimasi pembangkitan dengan memperhatikan batasan-batasan seperti batas daya aktif, batas daya reaktif, dan tegangan. Dengan adanya perubahan operasi pembangkit maka akan berdampak pada biaya pokok penyediaan tenaga listrik (BPP) sehingga didapatkan besaran BPP yang diperlukan untuk mencapai kondisi susut terbaik pada sistem Sulbagsel. Hasilnya, simulasi perubahan dispatch berdasarkan nilai incremental losses mampu menurunkan losses menjadi 2,03% dan simulasi optimal power flow mampu menurunakan losses menjadi 1,91%.

Electricity system operations in Sulawesi are carried out by prioritizing reliability, quality and cost efficiency. One important indicator in this regard is electrical energy losses. In Makassar and the surrounding region, which is the center of energy consumption, a significant increase in load is expected. However, there are major challenges related to power losses due to the long distance between the location of large-scale power plants and load centers, potentially causing large losses due to long transmission distances. To minimize power losses in the electricity system, there are two methods used, namely incremental losses and optimal power flow. Incremental losses analysis aims to evaluate and reorganize the distribution of generation throughout the system by considering the impact of power changes at each generation bus on overall power losses. On the other hand, the optimal power flow method focuses on generation optimization with respect to constraints such as active power limit, reactive power limit, and voltage. With the change of power plant operation, it will have an impact on the cost of electricity supply (BPP) so that the amount of BPP needed to achieve the best shrinkage conditions in the South Sulawesi system is obtained. As a result, the simulation of dispatch changes based on the incremental losses value is able to reduce losses to 2,03% and the optimal power flow simulation is able to reduce losses to 1,91%.
