Abstract

Semakin tingginya pemanfaatan sumber energi terbarukan berbasis inverter menyebabkan penurunan inersia sistem tenaga listrik sehingga kestabilan transien menjadi lebih rentan terhadap gangguan. Salah satu solusi yang dikembangkan untuk mengatasi permasalahan tersebut adalah penggunaan Virtual Synchronous Generator (VSG) yang mampu meniru karakteristik generator sinkron. Namun, performa VSG sangat dipengaruhi oleh kemampuan sistem penyimpanan energi yang digunakan. Oleh karena itu, penelitian ini menganalisis pengaruh integrasi Superconducting Magnetic Energy Storage (SMES) terhadap peningkatan kestabilan transien pada sistem VSG. Simulasi dilakukan menggunakan MATLAB/Simulink dengan model Single Machine pada kondisi gangguan hubung singkat tiga fasa dan dua fasa. Evaluasi dilakukan berdasarkan nilai Critical Clearing Time (CCT), respon sudut rotor, arus, tegangan, daya aktif, dan daya reaktif. Hasil simulasi menunjukkan bahwa integrasi SMES mampu meningkatkan nilai CCT pada gangguan tiga fasa dan pada gangguan dua fasa. Selain itu, SMES mampu meredam osilasi sudut rotor serta memperbaiki respon arus, tegangan, daya aktif, dan daya reaktif sehingga sistem menjadi lebih stabil selama kondisi transien.

The increasing utilization of inverter-based renewable energy sources has led to a reduction in power system inertia, making transient stability more vulnerable to disturbances. One of the solutions developed to address this issue is the implementation of a Virtual Synchronous Generator (VSG), which is capable of emulating the characteristics of a conventional synchronous generator. However, the performance of a VSG is highly dependent on the capability of the employed energy storage system. Therefore, this study analyzes the effect of integrating Superconducting Magnetic Energy Storage (SMES) on improving the transient stability of a VSG-based power system. Simulations were carried out using MATLAB/Simulink with a Single Machine model under three-phase and two-phase short-circuit fault conditions. The evaluation was conducted based on Critical Clearing Time (CCT), rotor angle response, current response, voltage response, active power, and reactive power. The simulation results demonstrate that the integration of SMES increases the CCT under both three-phase and two-phase fault conditions. In addition, SMES effectively suppresses rotor angle oscillations and improves current, voltage, active power, and reactive power responses, resulting in enhanced system stability during transient conditions.
