Abstract:
Photovoltaic systems have become an emerging field for power generation by using renewable energy sources to overcome the usage of conventional combustible fuels and the massive release of harmful gases. The majority of PV modules provided in markets gives (12 or 24V) but load may require other values. DC-DC converters are applied between the source and the load as power conditioning unit to regulate and boost up photovoltaic voltage to the desired output voltage. Duty cycle of the converter needs to be adjusted to obtain a constant level of voltage. In this project, the complete design consists of a module of solar cells, a DC/DC boost converter with its duty cycle using proportional integral (PI) controller, and load (BATTERY OR RESISTIVE). To improve the stability of a boost converter, the (PI) controller is implemented. This strategy is employed in a photovoltaic system to optimize its performance. The optimization algorithm, along with the PI controller, is utilized to adjust the duty cycle in response to the changes in the input caused by the variations in radiation and temperature. The entire system will be modeled and simulated using MATLAB to evaluate its effectiveness.
