Abstract:This paper presents a novel robust maximum power point tracking (MPPT) control for a grid connected photovoltaic (PV) system with reduced DC link capacitance. The voltage source inverter (VSI) integrating the PV system to the grid introduces a double line frequency ripple or current variation into the PV system. This ripple or current variation results in oscillation of operating point around the MPP, introducing an extra power loss from the extracted panel power. In order to reduce this ripple content, large … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
