Voltage Profile Improvement of the 20 kV Painan Distribution System with Multiple Distributed Renewable Energy Generation

Refdinal Nazir, Muhammad Nurdin, Eka Fitrianto


Abstract: This paper analyzes the
effect of multiple Distributed Renewable Energy Generation penetration on improving the performance of the B3 feeder typical distribution
system structure in Painan,
Indonesia. Analysis uses a simple concept of load and distributed generation current
injection at the distributed  main, lateral and sublateral lines. The algorithm begins from completion of the main
line variables, then uses an algorithm to complete the lateral line variables
associated with the main line variable, and finally calls algorithms to resolve
the sublateral variables associated with the lateral line variable. The results have shown
that integrating three Distributed Renewable
Energy Generation units to this distributed
system has increased the minimum voltage of the main line
from 17.35 kV to 20.37 kV, reduced active power loss from 1914.747 kW to
569.925 kW, and diminished reactive
power loss from 650.747 kVAr to 188.624 kVAr.
Keywords: Distributed Renewable Energy Generation (DREG); Distribution System (DS); Voltage profile; Active power loss; Reactive power loss
