Distributed Generation in Power System Network to Alleviate Voltage Sag

Abstract

Now a days there is increase in consumption of energy than generation. So we have to maintain additional generation as well as power quality for continuity of supply. One of the problems that effects power quality is Voltage Sag or dip. Distributed generation has gained a lot of momentum due to market deregulation, and development of new technologies. Distributed Generation (DG) is defined as generation located at or near the load centre which is being recognized as an environment friendly, reliable, and secure source of power. Now a day there is increase in integration of distributed generation into the distribution network to meet ever increasing demand. Inverter based DG will increase system voltage profile. This paper mainly investigates on impact of Inverter based Distributed Generation in a power system network during voltage sag. The proposed method is tested and the results of simulation are observed using Matlab/Simulink.
