Alokasi Optimal Pembangkit Tersebar Pada Sistem Distribusi Tenaga Listrik Untuk Meminimisasi Rugi-Rugi Daya

Abstract

This paper presents a new method to determine the optimal DG (Distributed Generation) location and capacity in radial distribution networks to minimize power losses. The proposed method is based on the power loss formula as a function of node currents or injection currents. To obtain the optimal DG location and capacity, only a single load flow solution (i.e. basecase load flow solution) is required. Furthermore, the calculation of bus impedance matrix or bus admittance matrix is also not necessary in the procedure to obtain the optimal DG allocation. The proposed method has been tested and validated using two IEEE test systems, namely the 12-bus and 33-bus systems. The test results show that significant power loss reduction can be achieved through the application of the method proposed in this paper.
