Abstract
In this paper, a suitable controller for Distribution Static Compensator (DSTATCOM) is designed for improving the power quality. Power Quality has become a major issue in the present power system network. The network complexity is increasing more rapidly and most of the loads are inductive in nature which draws more reactive power. This causes harmonics and voltage variations in power system. To maintain the proper operation of inter-connected power system, we are using one of the FACTS devices such as DSTATCOM. It provides suitable compensation and thereby maintains the desired power factor, voltage and also reduce the harmonic content in distribution network. The fuzzy logic controlled block diagram for DSTATCOM which is optimized using GA is incorporated and also it has been simulated. A comparative study of PI controlled and Fuzzy Logic Controlled DSTATCOM is also made. The simulation is taken out by MATLAB/SIMULINK and the result shows the effectiveness of GA optimized Fuzzy controlled DSTATCOM for improvement of power quality.
