A Review on D-STATCOM Control Techniques for Power Quality Improvement in Distribution

In this paper, a traditional PI controller Distribution Static Compensator (DSTATCOM) is suggested for reactive power compensation and power quality enhancement in distribution systems, and five various ways to obtain reference currents for a DSTATCOM are analyzed. The control algorithm for extracting reference current components has an impact on DSTATCOM's performance. Asynchronous reference frame theory and a new Adaline-based algorithm, as well as model predictive control (MPC), Sliding mode controller (SMC) -based STATCOM, and ANFIS-LMS-based control, are among the techniques used. When non-linear loads are added to a three-phase distribution system, the supply side voltage and currents become unbalanced, making the system appear out of phase. A DSTATCOM is used to get in phase voltage and current and rectified a balanced three-phase supply to solve the problem. DSTATCOM, the suggested traditional PI controller, will be implemented in MATLAB utilizing the SIMULINK model. The performance of this approach for controlling DSTATCOM is demonstrated by simulation and experimental findings.
