Photovoltaic Based Dc-Dc Multiport Converter with Distributed Generation

Abstract: The main objective of the paper is The growing concern for energy saving has increased the usage of LED- based Street Lights, Electronic Chokes, Compact Fluorescent Lamps, And Inverter-Fed Drives. Hence, the load profile seen by the electrical grid is undergoing a notable change as these devices have to operate from a dc source. Photovoltaic (PV) being a major energy source, the loads can be connected directly to the dc bus. A grid-connected PV system involves a power source (PV array), a power sink (load), and two power sources/sink (solar and ac grid), and hence, a power flow sharing system is required to balance the power flow among these sources. This method is reduce the burden of input voltage because whenever the solar output reduces then the input voltage share to AC grid so the distribution AC grid and solar panel is takes place
