“…Load shedding merupakan metode control prevetif dan ekonomis dalam mengurangi jatuhnya sistem, dimana dilakukan pada lokasi yang tepat sehingga dapat menaikkan tegangan secara signifikan sampai batas nilai toleransi yang diizinkan yaitu +5% dan -10% dari tegangan nominal [7][8][9]. Sebagai dasar pedoman untuk mendesain load shedding yang direkomendasikan oleh H. G. Sarmiento, dkk [10]. Oleh karena itu, diperlukan suatu perlakuan untuk memperbaiki penurunan daya reaktif yang mengakibatkan penurunan tegangan, maka dari itu diperlukan perlakuan dengan melakukan under voltage load shedding (UVLS).…”

Simulasi Under Voltage Load Shedding (UVLS) dengan mempertimbangkan integrasi pembangkit listrik tenaga bayu (PLTB). PLTB yang akan diintegrasikan ke dalam sistem interkoneksi Sulawesi Selatan milik PT. PLN (Persero) berada di daerah Sidrap sekitar 70 MW dengan menggunakan 30 turbin angin, menghasilkan 2,5 MW per turbin dan di daerah Jeneponto sekitar 62,5 MW dengan jumlah turbin angin yang sama. Kondisi angin yang berbeda dapat mempengaruhi sistem tenaga yang menyebabkan gangguan besar atau kecil, baik dalam pelepasan generator atau jalur transmisi. Berdasarkan permasalahan ini, penelitian ini bertujuan untuk melakukan simulasi pada daerah yang mengalami jatuh tegangan saat WPP berada di sistem Sulawesi Selatan. Metode sensitivitas dinamis disajikan dalam makalah ini. Dari hasil simulasi dan analisis, diperoleh lokasi load shedding di Makale, Palopo dan Latuppa dapat menstabilkan tegangan sistem namun menyebabkan area Poso berada dalam kondisi over voltage.

Summary A blackout is usually the result of increasing load beyond the transmission capacity of the power system. One of the main reasons for power blackouts is voltage collapse. To avoid this problem, the proper corrective measures called load shedding is required. In critical and extreme emergencies, under voltage load shedding (UVLS) is performed as a final remedy to avoid a larger scale voltage collapse. Therefore, UVLS is considered state of the art to achieve voltage stability. This review summarizes and updates the important aspects of UVLS; it also provides principle understanding of UVLS, which are critical in planning such defense schemes. Moreover, this article provides a discussion on recent state‐of‐art UVLS schemes applied in various power industries. Additionally, the pros and cons of the conventional and computational intelligence techniques are discussed. It is envisioned that this work will serve as one‐stop information for power system engineers, designers, and researches.
