Abstract

Pertumbuhan penduduk, bertumbuhnya industri, dan berkembangnya teknologi yang terus berlangsung menjadi faktor kunci yang mendorong kebutuhan daya listrik. Apabila kebutuhan beban meningkat maka daya pembangkitan juga akan meningkat. Maka diperlukan perhitungan yang optimal seperti Economic Dispatch (ED) yang merupakan salah satu metode optimisasi yang digunakan untuk menentukan alokasi daya yang lebih murah dari pembangkitan listrik. Namun, terdapat gangguan seperti penambahan kebutuhan beban dan kurangnya daya pembangkitan, yang dapat menimbulkan ketidakseimbangan. Dari ketidakseimbangan tersebut maka perlunya penerapan Optimal Load Shedding (OLS) untuk mempertahankan kestabilan sistem. Oleh karena itu, ED dilakukan dengan OLS untuk memenuhi kebutuhan beban. Metode yang optimal dalam penelitian ini adalah penggunaan metode Centralized Solution. Pada penggunaan metode ini akan mengembangkan perhitungan ED dengan OLS secara bersamaan apabila terjadi ketidakseimbangan. Untuk mempermudah penelitian dan melakukan evaluasi, penelitian akan dilakukan menggunakan simulasi komputer menggunakan software MATLAB. Hasil akhir yang didapatkan total biaya ED tanpa OLS cenderung lebih rendah yaitu sebesar $604.83 daripada tota biaya ED dengan OLS yaitu sebesar $1222.73 (Penambahan Beban) dan $682.73 (Pelepasan Generator) ini disebabkan karena adanya gangguan seperti penambahan beban dan pelepasan generator yang merupakan penyebab penambahan biaya. Namun, dengan begitu ketidakseimbangan daya pembangkitan dan kebutuhan beban bisa teratasi.

Population growth, industrial growth, and the ongoing development of technology are key factors that drive electrical power demand. If the load demand increases, the generation power will also increase. Therefore, an optimal calculation such as Economic Dispatch (ED) is required, which is one of the optimization methods used to determine the cheaper allocation of power generation. However, there are disturbances such as additional load demand and lack of generation power, which can lead to imbalances. From this imbalance, it is necessary to apply Optimal Load Shedding (OLS) to maintain system stability. Therefore, ED is performed with OLS to meet the load requirements. The optimal method in this research is the use of the Centralized Solution method. The use of this method will develop ED calculations with OLS simultaneously in the event of an imbalance. To facilitate research and evaluation, the research will be conducted using computer simulation using MATLAB software. The final result obtained is that the total cost of ED without OLS tends to be lower at $604.83 than the total cost of ED with OLS which is $1222.73 (Load Addition) and $682.73 (Generator Release) this is due to disturbances such as load addition and generator release which are the cause of additional costs. However, by doing so the imbalance of generation power and load requirements can be resolved.
