Power Maximization of a Photo Voltaic System Using LDRS
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2015, Vol 3, Issue 9
Abstract
In this we have proposed a photovoltaic system connected to the grid (220V/50Hz). The electric system is composed by a charge controller with the DC-DC boost converter is used along the automatic tracking system for further enhancing output power under variable isolation conditions and protecting the battery from being overcharged and over discharged condition. The Boost converter is used to overcome the lower output voltage of solar panel for not fulfilling the minimum charging voltage requirement of the battery thus more power extraction is possible from the solar panel to battery. The system includes a photovoltaic array, three LDRs sensors and a Dc/Ac converter. A maximum-power-point-tracking technique is used to operate in the optimum power condition. The Dc/Ac converter allows the adaptation of the PV system to the grid. The hysteresis technique is used to generate the output current waveform. All the command algorithms are implemented in a microchip microcontroller.
