Abstract
Kestabilan transien merupakan kemampuan sistem tenaga listrik untuk menjaga sinkronisme pada generator selama gangguan. Oleh karena itu, sistem membutuhkan waktu pemutusan kritis atau Critical Clearing Time (CCT) berdasarkan respons sudut rotor. Pemasangan Super Capacitor Energy Storage (SCES) bertujuan untuk memperbaiki CCT agar gangguan dapat dihilangkan sebelum generator terlepas dari sistem. Saat terjadi gangguan, SCES akan merespons sistem dengan menyerap daya mekanis berlebih dari Critical Generator (CG). Kemudian, optimasi peletakan SCES akan didukung oleh metode Boundary Controlling UEP Shadowing (BCU Shadowing) untuk menentukan CG berdasarkan generator yang memiliki indeks energi terbesar. Pada sistem Anderson dan Fouad 3-generator 9-bus, CG terletak di generator ke-2. Sementara pada sistem IEEE 7-generator 57-bus, CG terletak di generator ke-5. Penelitian ini akan membuktikan adanya peningkatan CCT rata-rata selama 0.01 detik apabila SCES diletakkan pada bus CG. Metode Critical Trajectory (CTrj) adalah metode untuk perhitungan CCT dengan menggunakan kehilangan sinkronisme (modified losing synchronism) sebagai kondisi titik akhir.

Transient stability is the ability of a power system to maintain synchronism of the generators during the disturbance. Therefore, the power system needs the Critical Clearing Time (CCT) refers to the responses of the rotor angle. Installing Super Capacitor Energy Storage (SCES) aims to improve the CCT so it will clear the disturbance before the generator is released from the system. When the disturbance happens, SCES will absorb the excess of mechanical power from the Critical Generator (CG). An optimization of SCES placement supported by the Boundary Controlling UEP Shadowing (BCU Shadowing) to determine CG based on a generator which has the biggest of energy index. On 3-machine 9-bus Anderson and Fouad system, the CG is located at the 2nd generator. While, the CG of IEEE 7-machine 57-bus system is the 5th of the generator. This final project proves the enhancement of average of CCT up to 0.01 second when SCES is placed on the CG bus. Critical Trajectory (CTrj) is a method to calculate the CCT uses modified losing synchronism as its endpoint condition.
