Han Su Yin* and Shwe Zan Aung
ABSTRACT
This paper presents the Reliability Enhancement by Distributed Generation (DG). The study of the test system used in this paper is on Kalay distribution system, located at Kalay Township, Sagaing Division, Union of the Republic of Myanmar. To estimate the reliability of the test system and load flow conditions, the test cases are modeled and evaluated using ETAP (Electrical Transient and Analysis Program) Software and Newton-Raphson Method. According to the result, Distributed Generation can improve the voltage profile and reliability indices. Moreover, the estimation becomes more accurate by considering load flow constraint. The difference cases are presented by comparing reliability index ENS (Energy Not Supplied). In this paper, optimal placement of Distributed Generation (DG) in the distribution system is discussed and premeditated, which can improve the voltage profile, loss minimization and system reliability enhancement.
