Abstract
Dalam menjaga kelangsungan dan keandalan sistem sangat penting, maka kestabilan sistem tenaga juga harus diperhatikan. Pada sistem tenaga listrik, analisis stabilitas transien berperan penting dalam menjaga keselamatan operasinal. Saat terjadi gangguan, maka sistem pengaman akan bekerja untuk melindungi dan mengamankan sistem kelistrikan. Setelah gangguan dapat dihilangkan dan sistem beroperasi seperti semula, belum ada jaminan bahwa sistem akan kembali ke keadaan semula. Misalnya, apabila terjadi beban tambahan, maka generator di sistem akan menjadi tidak stabil. Maka dari itu, fokus penelitian ini adalah penentuan generator kritis menggunakan metode modal analysis. Modal analysis memberikan informasi tentang eigenvalue dan participation factor. Sistem dikatakan stabil jika seluruh nilai eigenvalue bernilai negatif, jika terdapat satu saja nilai eigenvalue positif sistem dikatakan tidak stabil. Setelah itu, hasil dari metode modal analysis dibandingkan dengan metode Energy Index. Dengan penentuan generator kritis yang tepat, diharapkan mampu memperbaiki kestabilan pada sistem tenaga. Sehingga sistem tetap stabil dan bertahan dari gangguan saat terjadi gangguan. Pada penelitian ini didapatkan hasil dari modal analysis sistem Anderson dan Fouad 3-generator 9-bus, generator kritis terletak di generator ke-2. Sementara pada sistem Anderson dan Fouad 4-generator 9-bus, generator kritis terletak di generator ke-2. Hasil pada Energy Index dalam penentuan generator kritis sama dengan modal analysis sistem Anderson dan Fouad 3-generator 9-bus, generator kritis terletak di generator ke-2. Sementara pada sistem Anderson dan Fouad 4-generator 9-bus, generator kritis terletak di generator ke-2.

In maintaining the continuity and reliability of the system is very important, the stability of the power system must also be considered. In electric power systems, transient stability analysis plays an important role in maintaining operational safety. When a disturbance occurs, the protection system will work to protect and secure the electrical system. Once the disturbance has been removed and the system operates as before, there is no guarantee that the system will return to its original state. For example, if there is an additional load, the generator in the system will become unstable. Therefore, the focus of this research is the determination of critical generators using the modal analysis method. Modal analysis provides information about eigenvalue and participation factors. The system is said to be stable if all the eigenvalues are negative, if there is only one positive eigenvalue the system is said to be unstable. After that, the results of the modal analysis method are compared with the Energy Index method. By determining the right critical generator, it is expected to be able to improve the stability of the power system. So that the system remains stable and survives disturbances when disturbances occur. In this study, the results obtained from the Anderson and Fouad 3-generator 9-bus modal analysis system, the critical generator is located in the 2nd generator. While in the Anderson and Fouad 4-generator 9-bus systems, the critical generator is located at the 2nd generator. The results on the Energy Index in determining the critical generator are the same as the Anderson and Fouad 3-generator 9-bus modal analysis, the critical generator is located in the 2nd generator. While in the Anderson and Fouad 4-generator 9-bus systems, the critical generator is located at the 2nd generator.
