“…The results show that the SVSI ratio on the conditions of base loading and heavy loading (40% ) looks the most critical on the bus 30 when 15 % penetration of wind generator on buses 26 and 29. This value corrected due to active power contribution and reactive power of DG integration [16][17]. The addition of DG penetration level by 30% affects the shift in SVSI value which is increasingly towards a stable direction.…”

Related to environmental issues resulting from the use of traditional energy sources, drive usage of renewable energy is increasing. Changes in the structure of the network will certainly affect the changes in voltage stability. In this paper, discuss the impact of the stability after distributed generation penetration whose its output intermittent relatively. The simulation based PSAT software and tested into IEEE 30 bus system. Observation of voltage deviation and SVSI-index on some load buses in conditions before and after integration of wind generation. Load condition is a very determining factor of bus voltage stability index. This relates to the active power and reactive power needs that must be injected by DG penetration.

“…Sistem tenaga listrik bersumber dari pembagkit yang terdri dari PLTU (pembangkit Listrik Tenaga Uap), PLTA (pembangkit Listrik Tenaga air) dan PLTB (Pembangkit Listrik Tenaga Bayu), [1][2][3] bertempat jauh dari pusat-pusat beban sehingga diperlukan jaringan transmisi dan distribusi untuk menghubungkan. Terdapat peralatan lain untuk mendukung menyalurkan daya listrik tersebut yaitu transformator yang merupakan alat yang berfungsi untuk menaikan dan menurunkan tegangan.…”

Transformator merupakan unsur utama dan merupakan mata rantai terpenting dalam penyaluran dan distribusi tenaga listrik. Sehingga diperlukan sistem proteksi yang selektif, andal, sensitif, dan cepat untuk menjaga keandalan trafo. Salah satu komponen proteksi trafo adalah CT (trafo arus) yang berfungsi sebagai pembaca arus proteksi relay, apabila terjadi gangguan maka relay proteksi mendeteksi adanya keabnormalan sehingga memberikan sinyal trip pada PMT untuk memutus rangkaian listrik. Relay pada sistem proteksi trafo memiliki lokasi pengamanan yang berbeda. Di PT. PLN (Persero) UPT Cirebon, terjadi gangguan pada bay trafo yang mengakibatkan relay bekerja. Namun kerja relay ini tidak sesuai dengan lokasi gangguan yang terjadi. Setelah diinvestigasi didapatkan bahwa CT pada bay trafo memiliki desain peletakan yang kurang tepat sehingga mengakibatkan salah kerja relay (kurang selektif). Untuk memperbaiki kesalahan tersebut, maka dilakukan perubahan wiring CT pada trafo produksi lama. Perubahan wiring CT ini disesuaikan dengan ketentuan SPLN T5.003-2010 Tentang Standar Pola Proteksi Transformator Tenaga sehingga apabila terjadi gangguan relay bekerja sesuai dengan lokasi proteksinya. Hal ini terbukti pada saat terjadi gangguan setelah dilakukan perubahan wiring relay bekerja sesusai dengan fungsinya, sehingga prinsip sistem proteksi terpenuhi, yaitu selektif, andal, sensitif dan cepat.

“…Several studies have already been conducted focusing on the stability of the Sulselrabar system [8]. The integration of renewable generators into the Sulselrabar system has also presented stability issues [9]. Currently, there is a need for studies to evaluate the performance of the Sulselrabar system, particularly regarding stability issues.…”

This study proposes the application of a single-band power system stabilizer type 1A (SB-PSS1A) to enhance the damping ratio in multimachine systems. The mayfly optimization algorithm (MOA) method is employed to optimize the performance of the SB-PSS1A. The South Sulawesi, Southeast Sulawesi, and West Sulawesi regions of the Sulselrabar system are covered by the proposed control plan. To evaluate the effectiveness of the proposed controller, frequency domain analysis and time domain simulation analysis with varying load changes are presented. The accuracy of the MOA method is compared to the swarm intelligence method based on particle swarm optimization (PSO) and firefly algorithm (FA). The analysis results indicate an improvement in system stability, as demonstrated by an increased damping ratio, reduced oscillation overshoot in generator speed and minimum rotor angle, and faster settling time. By implementing SB-PSS1A on 14 generators using the MOA optimization method, a damping ratio of 0.5868 was achieved.
