Optimal Placement of Distributed Generation System to Improve Power Quality

Abstract

In the large power system, there exist different types of disturbances such as harmonic distortion, voltage Sag, voltage collapse and voltage swell. These disturbances are main causes of poor power quality in the distribution system. Out of which voltage sag is main power quality problem thus it is required to mitigate these problems to have a good power quality. This paper proposes the wind turbine based distributed generator that is designed in MATLAB simulation and detects the optimal placement of distributed generator with reliable size so that the voltage sag is eliminated. The distributed generator is used during overload condition and emergency condition to improves the power quality of the power system.
