Enhanced PLL (EPLL) Synchronization and HBCC Controlling of Grid-Interactive (PV-SOFC) Hybrid Generating System

Objective: In a grid-interactive (PV-SOFC) generation system, the inverter is main constituent. Further, quality of injected signal in utility depends upon control and synchronization. Thus, objective thispaper to single-phase for hybrid DC system obtain synchronization between grid renewable energy source (RES) inverted output signal. Methods/Statistical analysis: This paper suggests software modeling photovoltaic array (PV) solid oxide fuel cell (SOFC) power supply continue load demand. The enhanced phase locked loop (EPLL), hysteresis band current controller (HBCC) utilize system. benefit EPLL configuration beyond traditional PLL’s compose keep up change zero input voltage controlled oscillator (VCO). So, tracks thephase angle amplitude incremental conductance based MPPT technique implemented proposed architecture enhance system’s efficiency by maximizing extracted from PV configuration. addition, RES obtained with EPLL. simulation results design parameters are carried out MATLAB 2015. Findings: efficacy circuit confirmed through compensation twice time-frequency error, which introduced PLL. results, it observed that smooth frequency Moreover, performance index parameter (%THD) presence HBCC smaller than Novelty: introduces approach PV-SOFC Keywords: Photovoltaic (PV); maximum point tracking (INC-MPPT); synchronization; (SOFC); controller; (EPLL);
