Abstract
DCOPF dengan mempertimbangkan batas keamanan sistem merupakan pengembangan dari Optimal Power Flow dengan memperhitungkan adanya kontingensi pada saluran transmisi dan ramp rate generator. Gangguan kontingensi yang terjadi pada saluran transmisi dapat menyebabkan pemadaman total atau blackout dan kegagalan unit pembangkit dalam membangkitkan tenaga listrik. Pada sistem Sulselbar, blackout yang terjadi berlangsung hingga 5 jam karena disebabkan adanya gangguan kontingensi pada saluran transmisi. Untuk mengatasi gangguan blackout tersebut maka dilakukan perencanaan sistem tenaga listrik yaitu Security Constrained DCOPF mempertimbangkan pelepasan beban. Dalam menentukan perencanaan pembangkitan terdapat batasan-batasan yang harus dipenuhi dan tidak melanggar batasan, seperti ramp rate generator, kapasitas saluran, kebutuhan beban, dan kontingensi. Pelepasan beban digunakan untuk mengatasi agar unit pembangkit tidak mengalami pemadaman secara total dan tetap dapat melayani kebutuhan beban. Metode dalam perhitungan SCOPF yaitu dengan menggunakan Quadratic programming yang diterapkan kedalam software Matlab dan Matpower berdasarkan data batasan-batasan yang telah diambil. Hasil dari perhitungan SCOPF pada Matlab dan Matpower tersebut dapat digunakan untuk meminimalkan blackout yang terjadi di sistem Sulselbar.

Security Constrained DCOPF is the development of OPF by taking into contingency on the transmission line and generator ramp rate. Contingency disturbances that occur in transmission line can cause blackout and failure of generator unit for generate electricity. In Sulselbar system, blackout that occur last up to 5 hours due to the presence of contingency interference on the transmission line. To overcome the blackout disturbance, the electric power system planning, namely Security Constrained DCOPF, is considered load shedding. In determining the generation plan, there are constraints that must be fulfilled and do not exceed the limits, such as generator ramp rate, line capacity, load demand, and contingency. Load shedding is used to resolve the generator unit so as not to experience blackout and still be able to service load demand. The method in calculating SCOPF is by using Quadratic programming which is applied to Matlab and Matpower software based on data on the limits that have been taken. The results of SCOPF calculations on Matlab and Matpower can be used to minimize blackouts that occur in the Sulselbar system.
