Modeling of the three-phase converter using a predictive controller based on the dynamic voltage restorer model for improving power quality

Abstract

Abstract Sensitive loads in the distribution system can be easily influenced by issues with power quality. Improving power quality in the distributed system is a major concern. Sag/swell, harmonics, flicker, distortions, etc are delivery consistency concerns on the distribution side. One of the major power quality issues is taken into account by this paper voltage sag/swell. Flexible AC transmission systems (FACTS) with MPCbased voltage source inverter orcurrent source inverter are considered for voltage issues. The model is used in every switching state of the converter to simulate the behavior of device variables. The predictions are measured using a cost function that weighs the degree of precision of control goals. The most successful switching condition is then produced for CSI and VSI. Dynamic Voltage Restore (DVR) and Unified Power Quality Conditioner are the FACTS systems which are used on the distribution side (UPQC). The voltage drop in the system is detected by both devices and restored by injecting the appropriate voltage into the system. Injected Voltage Part Blocks of the Voltage Source Inverter (VSI) or Current Source Inverter (CSI) DVR can be used (CSI). The predictive current control method for DVR with Current Source Inverters(CSI) after duality with Voltage Source Inverters is compared to THDs for voltage deflection/wave amplitude in this paper (VSI). In a MATLAB setting, the simulation is performed.
