Abstract

In this-paper, a methodical methodology is introduced for the modeling-and regulation of-a-non-ideal Boost converter integrated with a solar PV system, designed for battery storage. Both solar PV and boost converter are nonlinear systems. Therefore, to design a suitable controller, mathematical modeling becomes essential. This article outlines the development of a linearized model for a solar photovoltaic (PV) system. The linearization process involves the system being approximated around the point of maximum power, and this approach is used to ensure an-accurate-representation-of-the-system. The linearized model is then integrated with the non-ideal boost converter. Then, the overall linearized mathematical model of the entire system is evaluated. This mathematical model is used to-design-a PI controller-for-a solar PV integrated Boost-converter. The method of stability-boundary-locus (SBL) is employed to modify the PI controller parameters using particular frequency domain parameters. The outcomes of the MATLAB simulation indicate that the controller that was designed performs well even when atmospheric factors, such as temperature and irradiance, are altered.
