Design of a Synchronous Reference Frame Controlled Fuzzy Logic Based Distribution Static Compensator to Enhance Distribution System Power Quality

Abstract

The demand for enhanced power quality in distribution systems has increased due to the widespread utilization of various AC loads, including rectifiers, inductive loads, and variable speed drives. When these nonlinear loads are combined with renewable energy sources, harmonics are introduced in the system. These can affect the way other equipment in the network works and leave the system vulnerable to disturbances. Integrating DSTATCOM can address these power quality issues. The conventional PI controller is inadequate for addressing power quality challenges in dynamic power systems. This is due to its limited ability to handle nonlinear and time-varying dynamics, which are common in modern power systems. Consequently, the fuzzy logic controller-based DSTATCOM is engineered to address dynamic and multiple power quality issues. The efficacy of the suggested configuration against conventional PI regulators and assess its robustness and efficiency are evaluated. Through MATLAB simulation studies, the fuzzy logic controller-based DSTATCOM demonstrates superior performance in mitigating power quality issues by improving voltage profile, power flow, and power factor by compensating reactive power and reducing harmonic issues, and the results are compared to traditional PI controllers. This innovative solution offers improved stability and reliability in dynamic power systems, making it a promising alternative for enhancing overall system efficiency.
