Inverter current control for reactive power compensation in solar grid system using Self-Tuned Fuzzy Logic Controller

The solar photovoltaic (PV) systems have gained more attention in renewable energy production due to their cost efficiency and reliability. Typically, reactive power compensation harmonics elimination are challenging demanding tasks for improving the efficacy of grid-connected PV systems. For this purpose, many research works developed different converter controller topologies solving quality issues grid-PV But, it limits problems increased harmonics, computation complexity, inefficiency reduced performance outcomes. Thus, aims develop an integrated hysteresis current Self-Tuned Fuzzy Logic (SFLC) based MPPT controllers eliminating unbalanced single-phase grid Also, helps extract maximum amount from array. LUO is deployed reduce ripple contents. Phased Locked Loop (PLL) synchronization performed maintain phase angle, frequency magnitude levels source power. Moreover, inverter has been specifically designed THD system under IEEE519_1992 regulations. During experiments, both simulation hardware results evaluated validating proposed design.
