Penentuan Kapasitas dan Lokasi Optimal dari Pembangkit Tersebar pada Jaringan Distribusi Penyulang Nila di Gardu Induk Metro

Abstract

Installation of distributed generation (DG) is one alternatives to reduce power loss in distribution network. However, the placement of DG with non-optimal capacity and location may affect the voltage profile and voltage stability. This paper aims to find the optimal capacity and location of DG in order to reduce active power losses and improve the voltage profile and the voltage stability index. The simulation is performed by installing a DG on distribution network case studies i.e. IEEE 30 bus system and on the Nila feeder of Metro substation. Two types of DG are used for this simulation, i.e. DG that only produce active power and DG that produce both active and reactive power. Power flow calculations are performed using the forward/backward sweep method and all programming is written using MATLAB software. Simulation results show that the method can obtain the optimal capacity and location of DG. After installation the DGs, power losses, voltage profile and voltage stability index on each bus in Nila feeder have improved.
