Performance Enhancement of DC Load and Batteries in Photovoltaic System
To avoid the pollution and to save the non conventional resources, use of renewable energy sources such as wind energy, bio gas, hydro and solar potential has increased and become essential to adopt a low cost generating system in remote areas. Besides the variety of energy sources, solar power advantages are easy to make apparent compared to other methods. For many years, solar energy is the series source of vast amounts of freely available energy, but modern technology has harnessed it. In this paper a proper battery charge controller used in the Standalone Photovoltaic PV system. The power is transfer to the dc load and manages storage level available in this proposed technique. From the PV array the maximum power is extracted by using three different methods. In this proposed technique ‘perturb and observe’ and the ‘incremental conductance’ control methods and algorithms are analyzed. The system modelling as well as simulation results are presented.
