PERFORMANCE ANALYSIS OF CLOSED LOOP CONTROL OF DUAL STAGE GRID CONNECTED SOLAR SYSTEM

Abstract: This review paper presents the dual stage grid-connected solar system. This technology is still under development phase. Current harmonic mitigation, reactive power correction, and load voltage regulation are all common uses for power electronics converters. It necessitates dc link voltage support, that can be delivered by any source of energy such as solar, wind, or geothermal, that serves as a voltage source and also injects the active power generated by the source. With the online estimation of the reference power accessible, the fluctuating nature of power owing to changes in solar radiation and temperature of injected power may be compensated for. The simulation studies are carried out for 3-phase application using power system simulator.
