Abstract

This project proposes a power flow management algorithm for photovoltaic system feeding DC load is presented. The growing concern for energy saving has increased the usage of LED-based street lights, electronic chokes, compact fluorescent lamps, residential dc loads 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 aforementioned 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 (utility and battery), and hence, a power flow management system is required to balance the power flow among these sources. A unique control algorithm is developed for selecting the operating mode of the converter by sensing the battery voltage. Detailed simulation studies are carried out in MATLAB/Simulink environment.
