Abstract

Distributed Generation (DG) is a small-scale power plant located close to the center of load. Goa Lawah feeder is a broadcast that is close to the potential of DG namely the Mini Hydro Power Plant on the Unda River in Klungkung Regency. In this research the optimization of Distributed Generation placement to Goa Lawah feeder. Optimization of Distributed Generation placement aims to reduce the value of loss of power that exist in the feeder Goa Lawah. The results of the research obtained at the point of bus 123 by Distributed Generation placement using Particle Swarm Optimization (PSO) method, with power loss 41 kW (44%). The initial loss before the Distributed Generation interconnection of 72 kW after the Distributed Generation interconnection to 31 kW.

Summary

PENDAHULUAN

Energi listrik merupakan energi yang sangat bermanfaat bagi kehidupan manusia. Laju pertumbuhan ekonomi dan pertambahan penduduk merupakan penyebab masalah penyediaan energi listrik di masa datang. Pembangkit listrik tersebar dengan kapasitas kecil disebut dengan Distributed Generation (DG) yang biasanya terletak dekat dengan beban pada sistem distribusi tenaga listrik [1]. Salah satu cara untuk menurunkan rugi-rugi daya pada jaringan distribusi tenaga listrik yaitu dengan. Penyulang Goa Lawah merupakan JTM yang di suplay dari Gardu Induk Gianyar, dengan kapasitas daya 60 MVA. Dilakukan optimasi penempatan Distributed Generation pada Penyulang Goa Lawah untuk menurunkan rugi-rugi daya aktif menggunakan metode Particle Swarm Optimization. Sistem penyaluran daya listrik pada sistem jaringan distribusi primer dapat dibedakan menjadi tiga yaitu, Saluran Kabel Udara Tegangan Menengah (SKUTM), Saluran Udara Tegangan Menengah (SUTM), Saluran Kabel Tegangan Menengah (SKTM). Sistem penyaluran daya listrik pada jaringan distribusi sekunder dapat dibedakan menyadi dua yaitu, Saluran Udara Tegangan Rendah (SUTR) dan Saluran Kabel Udara Tegangan Rendah (SKUTR)
