Active power loss minimization in radial distributed micro grid incorporating distribution generators

Abstract

Now-a-days, Micro grid is getting more and more attractive due to its relative advantages. In this paper, the integration of distribution Generation (DG) into the radial distribution network is taken for analysis. Normal load flow analysis cannot be applied to the radial distribution network since the R/X ratio is very high. Hence Forward/Backward sweep load flow analysis is implemented to IEEE 33 bus system. Different distributed energy sources are introduced in different location with same ratings. The results prove that the introduction of DGs considerably reduces the active power loss in the test system and improves the voltage profile.
