Dynamic Voltage Restorer Integrated with Photovoltaic-Thermoelectric Generator for Voltage Disturbances Compensation and Energy Saving in Three-Phase System

The dynamic voltage restorer (DVR) combined with a photovoltaic–thermoelectric generator (PV-TEG) system is proposed for disturbance compensation in the three-phase four-wire distribution system. PV-TEG hybrid energy source used DVR to improve ability deep and long-period power quality compensation. In addition, will save grid consumption when module generates sufficient meet load demand. An enhanced variable factor adaptive fuzzy logic controller (VFAFLC)-based maximum point tracking (MPPT) control scheme extract possible from PV module. Since TEG combine generating power, can work efficiently sag/swell, outage compensation, conservation mode minimum storage facilities. in-phase method three-leg inverter (VSI) circuit are chosen present better and/or To confirm effectiveness of integrated system, simulation-based investigation carried out four different operational modes MATLAB software. study results that compensate disturbances less total harmonics distortion (THD) also under consumption. Moreover, VFAFLC-based technique performs achieve (MPP) quickly accurately, thereby improving efficiency
