Abstract
Kementrian ESDM menyatakan, pada tahun 2008 hingga 2027, pertumbuhan kebutuhan energi listrik akan mengalami kenaikan sebesar 6,1% per tahun dengan asumsi pertumbuhan penduduk sebesar 1,3% (RUKN, 2008). Kenaikan kebutuhan energi listrik ini dapat menyebabkan ketidakseimbangan sistem seperti peristiwa jatuh tegangan hingga penurunan pasokan daya yang berdampak pada peristiwa black out. Misalnya, pada Agustus 2015 telah terjadi pemadaman total di Jakarta-Banten selama 3 jam dan pada awal September 2018 telah terjadi pemadaman total di Cirebon akibat adanya kontingensi di sistem JAMALI 500 kV (Kompas, 2018). Oleh karena itu, dalam menjaga kestabilan sistem backbone JAMALI 500 kV, perlu dilakukan analisis perencanaan sistem kelistrikan yang optimal dan pertimbangan pelepasan beban untuk mencegah terjadinya black out. Hal ini dapat dilakukan dengan melakukan analisis security constrainted optimal power flow (SCOPF) untuk mendapatkan data eksisting beban sehingga dapat dilakukan perencanaan sistem kelistrikan yang optimal serta pelepasan beban minimal untuk perbaikan sistem setelah terjadi kontingensi. Metode yang digunakan untuk menyelesaikan masalah SCOPF adalah quadratic programming (QP) yang dijalankan pada software Matpower. Analisis perencanaan sistem JAMALI 500 kV ini diharapkan mampu mengantisipasi terjadinya kontingensi serta meminimalkan biaya pembangkitan dan jumlah pelepasan beban yang optimal.

The Ministry of Energy and Mineral Resources stated that the growth of electricity demand in 2008 until 2027 would increase by 6,1% per year assuming a population growth of 3,1% (RUKN, 2008). This increase in electrical energy demand can cause a system imbalance such as voltage drop and a decrease in power generation that has an impact on black out events. For example, in August 2015, there was a total black out in Jakarta-Banten for 3 hours and in September 2018, there was a total black out in Cirebon due to contingency in the 500 kV JAMALI system. Therefore, in maintaining the stability of the 500 kV JAMALI backbone system, it is necessary to analyze the optimal electrical system planning and consider the load shedding to prevent the occurrence of black out. This can be done by conducting a security constrained optimal power flow (SCOPF) analysis to obtain the existing load data so the optimal electrical system planning can be carried out and minimize the load shedding to improve system after contingency occurs. The method that used to solve the SCOPF problem is quadratic programming (QP) which is run on Matpower software. The analysis of the 500 kV JAMALI system planning is expected to be able to anticipate the occurrence of contingencies and minimize generation costs and the optimal amount of load shedding.
