The Maximum Power Shooting of the Thermollectric Generator (GTL) uses the Perturb and Observe (P&T) algorithm

Revealing the maximum potential of the thermollectric generator: Application of Perturb and Observe (P&T) Algorithm

The thermollectric Generator (GTL) is a system that converts heat into voltage through temperature differences on the heat and cold side. This study discusses the maximum power trace for the GTL that was built using the Perturb and Observe (P&T) algorithm. The system utilizes the Ina219 sensor as a current reader, GTL to convert heat into voltage, and DC-DC converters as voltage controllers. The temperature on the GTL heat side is changed to keep the cold side temperature constant. The voltage produced by the GTL then becomes input for the DC-DC converter. This is where the P&O algorithm plays a role, by manipulating pulse width (PWM) based on input and output power. The purpose of this study is to implement the MPPT P&O algorithm in GTL and maximize the power produced.

The P&O algorithm works by raising or lowering duty cycle based on output power. In this study, the maximum power achieved was 1,8684 watts. The P&O algorithm is one of the most commonly used methods in the maximum power trace (MPPT) for renewable energy systems such as GTL. The working principle is quite simple:

Perturb: Algorithm makes slight changes to the control variable (in this case, duty cycle of the DC-DC converter) to change GTL output power.
Observe: Algorithm then observes changes in output power that occurs due to changes in the control variable.
Decide: Based on observation, the algorithm decides to increase or reduce the control variable to achieve maximum power.

The Advantages and Disadvantages of the P&O Algorithm

The P&O algorithm has several advantages, namely:

Relatively simple: The implementation of this algorithm is quite easy, so that it can be applied with relatively cheap components. Easy to understand: The working principle is easily visualized and understood, so that it is easy in the process of debugging and development.

However, the P&O algorithm also has shortcomings, namely:

Convergence speed: This algorithm tends to be slow in achieving maximum power, especially in the condition of rapid load changes. Risk of oscillation: P&O algorithm can cause output power oscillation, especially when close to the maximum power point.

The Importance of the P&O Algorithm in GTL

The P&O algorithm plays a crucial role in maximizing the power produced by the GTL. By manipulating the pulse width (PWM) based on input and output power, the algorithm is able to achieve maximum power. The results achieved in this study show that the GTL is able to produce significant power with the application of this algorithm.

The Future of GTL Technology

For further research, a more sophisticated development of the MPPT algorithm with a higher convergence speed and better stability is necessary. In addition, the development of more efficient GTL design is also important to increase the power of output and energy conversion efficiency. By continuing to develop a better GTL technology and MPPT algorithm, GTL has great potential to become an alternative energy source that is environmentally friendly and sustainable.

Conclusion

This study shows that the P&O algorithm is effective for maximizing the GTL output power. The results achieved show that GTL is able to produce significant power with the application of this algorithm. The P&O algorithm is a simple and easy-to-understand method for maximizing power, but it has some shortcomings, such as slow convergence speed and risk of oscillation. Further research is necessary to develop a more sophisticated MPPT algorithm and more efficient GTL design.
