Scientists in India have created a wind solution system in a tree form that combines wind turbines and a PV system with trackers with two axis. The team constructed a hardware-in-the-loop prototype that can generate up to 444.5 WH per day.
A research team led by scientists from the India’s Dayananda Sagar College of Engineering has developed a tree type of PV-Wind Power System for off-grid applications.
“A hybrid tree is a synthetic construction that looks a lot like a real tree, with solar panels or wind turbines that are installed on its branches. It will make the supply of electricity to lighting loads, mobile phones, household appliances, laptops and electric vehicles possible, making it a suitable source of energy for green towns. “To maximize the energy output, PV panels must be oriented perpendicular to the rays of the sun. This study includes an automated two-axis intelligent solar stretching system that automatically positions PV panels to achieve optimum energy output from any part of the world.”
Dubbeds windplug hybrid tree (WSHT), the system contains a pole that contains a wind turbine (WT) on top, with different branches with two-axis sun fractors.
Initially, the WSHT was simulated in Matlab/Simulink, using one fixed PV panel, one PV panel on a two-axle solar monitoring system and one wind turbine system. Both PV panels had a nominal capacity of 100 W, while the WT had a nominal capacity of 500 W. A microcontroller system is used to control the orientation of the two-axis tracker using a mathematical model. It uses entrances such as GPS data and data from a Gyro orientation sensor and a digital compass.
With the help of the typical WT variables, the scientists also modeled the WT unit at different wind speeds (m/s).
After the simulation, the team built a semi-physical model that uses two real 100 W PV panels, one of them fixed and the other on a two-axle tracker and a simulated 500 WT WT, who used data from a NASA database.
The WSHT was placed in the Bangalore region in India and measured for four days between 6:00 and 18:00. The days were 5 January, 5 May, 5 September and 5 December 2024. The system always used the WT, while the PV source changed. It used the two-axis or fixed PV for tilting corners of 18 °, 15 ° or 10 °.
The prototype underwent extensive tests and the following system appeared to require minimal operational energy.
“The proposed WSHT can generate up to 444.5 WH/day with a two -axle tracking system and 409.5 WH/day with solar panels installed at a fixed angle,” the researchers emphasized. “The highest output of the solar component was determined as 144 WH/day with a two -axle tracking system and 109 WH/day with solar panels at a fixed angle. Wind turbines generate 300.5 WH/day.”
The system can be used to feed lighting taxes, mobile phones, household appliances, laptops and electric vehicles.
It was presented in the study “Intelligent two-axle solar tracker for hybrid tree system for renewable energy“Published in Franklin Open.
