Abstract
Sebanyak 9.539.526 konsumen listrik di Jawa Timur masih cenderung
mengalami peningkatan jumlah dari tahun ke tahun. Peraturan baru
tentang pencabutan tarif dasar listrik pada Januari 2015 tidak menurunkan
jumlah pelanggan. PT. PLN dituntut untuk tetap menyediakan listrik yang
berkualitas, handal dan murah. PT. PLN harus terus berinovasi,
memperbaiki dan menjaga system distribusi agar berjalan dengan baik.
Overload sewaktu-waktu bisa terjadi dengan jumlah pelanggan yang
telah mencapai 9.539.526 di Jawa Timur. Pelepasan beban adalah salah
satu cara menjaga kestabilan sistem kelistrikan dan menjaga standart
tegangan tetap pada batasnya untuk menjaga mutu listrik itu sendiri
sebagai produk utama dari PT.PLN . Oleh karena itu, kami mengusulkan
pada penelitian ini sebuah system pelepasan beban berbasis event-driven
yang menggunakan analisa aliran daya metode network topology dan
logika fuzzy. Logika fuzzy mempertimbangkan dua faktor yaitu nilai
tegangan dan nilai positive sequence voltage ranking index. Nilai positive
sequence voltage ranking index menunjukkan bus terlemah. Semakin
kecil nilai positive sequence voltage ranking index maka semakin lemah
juga bus tersebut. Proses defuzzifikasi pada nilai tegangan dan nilai
voltage ranking index mampu menghitung nilai spesifik beban yang harus
dilepas. Hasil dari pengujian sistem event-driven load shedding
menunjukkan bahwa saran yang dihasilkan untuk melepas suatu bus tidak
hanya berdasarkan nilai tegangannya saja, namun dengan memperhatikan
nilai voltage ranking index untuk indikator bus terlemah. Sistem
pelepasan beban berbasis event-driven membantu menentukan bus yang
harus dilepas dan jumlah beban spesifik yang harus dilepas, sehingga
proses pelepasan beban menjadi lebih cepat.
==================================================================================================================
A total of 9,539,526 Electric consumer in East Java still tends to
increase From Year to year. The new regulations state about revocation
electricity rates on January 2015 will not decrease a number of customer.
Improved customer is comparable with improved of economic level and
the need for electricity continues to grow. PT. PLN must make sure that
provide a qualified electrical, reliable and cheap. PT. PLN must keep
innovating, improving and maintaining distribution system to keep the
system running properly. Overload could happen anytime with customers
who have reached 9,539,526 in East Java. Load shedding is the one of
solution to keep the stability of electrical system and keep the limit voltage
standard for keeping power quality as a main product of PLN itself.
Therefore we propose in this research an event-driven load shedding by
using network-topology method of load flow and fuzzy logic. The fuzzy
logic use two variable from load flow analysis, there are voltage
magnitude and index value from positive sequence voltage ranking index.
Value of positive sequence voltage ranking index showed the weakest bus.
Smaller value of voltage ranking index, weaker of bus. Defuzzifycation
process on voltage magnitude and ranking index can calculate a specific
value of load must be shed. The result of testing this system show that
load shedding is not based on the voltage magnitude only, but also using
voltage ranking index as indicator of sensitivity of bus. Event driven load
shedding can give the information about the bust must be shed and the
specific value of load must be shed quickly.
