Optimal Sizing, Placement and Performance Analysis of DSTATCOM with Improved Controller without Current Sensors

The performance analysis of Distribution Static Compensator (DSTATCOM), when it is placed in an optimized location with an improved controller without current sensors is presented in this paper. To obtain optimal location, Ant colony optimization technique is used for the placement of DSTATCOM. To incorporate this compensator in load flow analysis, the modelling is done and rating of DSTATCOM is obtained. The performance analysis of improved controller is presented after placing the DSTATCOM in optimized location with optimized size. The actual voltage at bus where DSTATCOM is placed and DC voltage of the converter is taken as control parameters. The proposed optimization placement technique is tested for 207 bus practical distribution system using MATLAB. The performance analysis of studied systems with controller for different operating scenarios such as sag, swell are investigated in MATLAB/SIMULINK software environment.
