Implementation of a Dstatcom for Improving of Power Quality in the Local Distribution Grid by Using Fuzzy Logic Based Svpwm Technique

Abstract

The integration of renewable energy sources results in an increase in balancing corporate and industry load, which presents a number of power quality issues in the current environment. Highly sensitive, linear, non-linear, or imbalanced loads among grid-connected commercial utilities are among the demands operated by hospitals. The priority and diversity of these loads also result in significant issues with the quality of electricity within a distribution system for the neighborhood. Its broad divergence causes the injection of harmonics or reactive power imbalance. To address reactive electrical inequalities, neutral current reimbursement, load balancing, and harmonic abatement, the use of Distribution Static Comp (DSTATCOM) is suggested. The current study intends to improve the quality of electricity in the City Distributed Grid by generating pulses of switching during IGBT switching at the DSTATCOM using an Irregular Type-2 Fuzzy Logical Controllers (IT2FLC) equipped with a Recurrent Least Square ( ) filter. In regard to harmonic reduction, the suggested approach performs better than the Type 1 fuzzy algorithm controller and the Conventional PI controller. The suggested system is simulated using MATLAB software for efficient implementation. However, this proposed method has not looked at the first order, second order, or fifth order harmonics. Consequently, even if the system's efficiency will rise, we can say that the fuzzy in SV PWM technique is what's causing the system to perform better.
