The abundant use of energy from photovoltaic (PV) panels introduces many challenges in the whole power system scenario in the form of grid integration. A typical grid-connected photovoltaic (PV) system consists of a power converter to connect these sources to the grid. Most readily available converter topologies are designed to work under a constant source at its input, and hence they exhibit peculiar characteristic when connected to a variable current source, the PV panels. This paper thus intends to explore the dynamics and stability of the intermediate phase that is controlled and regulated output of a PV-fed boost converter under an ohmic load condition. The simulation platform is used for designing the PV circuit model and gain model of converter and also to demonstrate the supremacy of one controller over other. The classical PI controller is chosen for comparison with the controller designed using Youla parameterization. This technique yields a simple and defined solution to the problem through an arbitrary, proper and stable function named as Q parameter. The controller performance is compared based on the variation in output response due to variation in solar irradiance and load.
