THE IMPACT OF DISTRIBUTED GENERATION ON IEEE BUS SYSTEM

Abstract

Distributed or dispersed generation (DG) is small scale power generation system that is typically
connected in the distribution system. It is also known as embedded generation (EG). It is usually connected in the
distribution system to improve the reliability, to increase the voltage profile and to reduce the line losses of the system.
These impacts could be achieved with optimal allocation and size of DG. Power losses are categorized as real power
loss and reactive power loss. The resistance of lines gives rise to the real power loss and reactive power loss is caused
due to reactive elements embedded in the system. Power loss in a system could be reduced by controlling the reactive
power and regulating the node voltages. In this paper, the investigation is done to study the impact of multi DGs on
power losses. The study has been carried out on IEEE bus system. The analysis of the results showed that by increasing
the number of DGs in the system to reduce losses is not beneficial. In this paper, it is concluded that the optimal number
of DGs are also important parameter to reduce the losses.
