Autonomous Led Street Lights Based On Hybrid Renewable Sources

Abstract

In this artical, the arrangement of solar photovoltaic (PV)/Wind energy system is used for power generation. During day time, solar radiation falls on the panel, and then the power can be produced. During night time, due to the Emission of photons from the vehicle headlight, the power is produced from the solar PV panel. The Wind Turbine is used to generate electricity from the rotation of the wind blade due to the movement of vehicles by Vertical Axis model. The output of the solar and wind system fed into Buck-Boost converter to high voltage level. The simple P&O control method is used to pathway the operating point of the system at which highest power can be obtained. The Power obtained from different sources is connected to the dc bus in parallel connection. Here the energy required for the load to be taken from the dc bus and excess power will be stored in a battery and also insufficient power, the battery will discharge the power to load. The model of a structure is developed in MATLAB- SIMULINK.
