Fuzzy Control Based iUPQ Controller to Improve the Network of a Grid Organization

This paper presents an improved controller for the dual topology of the unified power quality conditioner (iUPQC) extending its applicability in power-quality compensation, as well as in grid applications. The main reason for the poor quality of energy is the harmonic currents, poor power factor, and supply voltage variations, etc. Power quality problems have received much attention these days because of their impact on both utilities and customers. Voltage sag, swell, stops for a moment, under voltages, the voltage noise and harmonics are the most common power quality disturbances. This approach provides a quality offset energy indirectly from the load voltage and source current. Using the controller, beyond the traditional power quality features UPQC, including voltage sag/swell compensation the iUPQC will also provide reactive power support to regulate not only the load-bus voltage but also the voltage at the grid-side bus. In other words, the iUPQC will work as a static synchronous compensator (STATCOM) at the grid side, while also providing compensation traditional UPQC in partial load side or network. The implementation of the proposed concept provided is to verify the new functionality of the equipment by using the MATLAB / SIMULINK program
