Advanced Control Method for Improving Power Quality of Microgrid Based on SVPWM Technology

Abstract

At present, the world economy as a whole stress the need for sustained and quality services in all sectors. Most industries are dependent on electricity and different electrical equipment and, as a result, maintaining energy quality has become a major issue for all industries to flourish and profitably. The Distribution Static Synchronous Compensator (D-STATCOM) is an advanced device-based power electronics device that can be used to control the power flow of distribution lines.Space Vector Pulse Width Modulation (SVPWM) is an advanced, intensive computational PWM method. In this paper, SVPWM technology based on Particle Swarm Optimization (PSO) is used to avoid the computational complexity used in traditional implementations. The integral proportional controller is adjusted by means of a particle swarm optimization (PSO) algorithm to improve the response performance of the switch angular. In the design of the PSO algorithm, adjust the Pi controller parameters kp and ki, so that the switching angle can achieve the best parameter values.PSO is required to determine the optimal switching angle while maintaining the base voltage, which can reduce some of the higher harmonics. To promote this technology, it can be extended to multi-stage inverters. When any loading effect, the structure of the system can be introduced to restore the bus voltage, and the control algorithm using the PSO controller effectively control the amount of power without problems under fault conditions. The simulation results show that the new D-STATCOM based on SVPWM can achieve better control and improve system efficiency.
