Abstract

This paper presents the design and implementation of a dual inverter-based grid-connected photovoltaic (PV) system incorporating PI (Proportional-Integral) and FOPID (Fractional-Order Proportional-Integral-Derivative) controllers, along with a Quadratic Boost Converter (QBC) for enhanced energy conversion and grid integration. In order to guarantee optimal DC-AC conversion from the photovoltaic array and smooth grid integration, the dual inverter system features cascaded voltage source two level inverters (DI). Enhancing power quality, improving the system's dynamic response, and making sure the injected current satisfies the necessary requirements while lowering harmonic content are the main goals. While the FOPID controller is used to enhance the system's transient response and provide better dynamic performance under changing irradiance and grid disturbances, the PI controller is employed for steady-state control. The Quadratic Boost Converter is a great option for PV applications since it also has a high efficiency, a high step-up voltage conversion, and lower switching losses. The FOPID controller reduces settling time by 43% and overshoot for grid current by 38% when compared to the PI controller, according to a comparative study of the two controllers. Furthermore, the grid current's Total Harmonic Distortion (THD) is decreased from 4.41% (PI) to 4% (FOPID). These outcomes demonstrate how well the twin inverter-based PV system with the QBC works and how the FOPID controller provides better dynamic performance for grid-tied applications.
