This research aims to enhance the efficiency of photovoltaic systems by proposing two innovative methods for maximum power point tracking (MPPT). We used the beluga whale optimization (BWO) algorithm, so we can adjust the gain of the PI controller. Volatility around MPP and failure accuracy under rapidly changing isolation are among the known drawbacks of traditional MPPT algorithms. To overcome these drawbacks, we proposed a theory that combines Perturb and Observe (P&O) with BWO, based on the controller of proportional integration (PI) and fractional order proportional integration (FOPI). The study compares the new techniques with existing traditional algorithms such as P&O and IC in terms of their efficiency, complexity and ease of implementation. Simulation tests conducted using Matlab indicate that the proposed hybrid FOPI-BWO method achieves an average tracking efficiency of about 97.05% and a voltage gain of 2.348, in the PI-BWO method it achieves an efficiency of 96.12% and a voltage gain of 2.322, and the IC-MPPT theory achieves an efficiency of 95.5% and a voltage gain of 2.261. , while the P&O-MPPT theory achieved an efficiency of 94.02% and a voltage gain of 2.241.It is clear that the two proposed algorithms perform better than traditional algorithms in terms of energy overshoot, ripple, and response time.

“…Recently, global warming, environmental issues, and the depletion of natural fuels such as gas, oil, and coal have led researchers worldwide to consider using renewable energy sources [1]- [7]. Since the voltage generated by the renewable energy sources is in DC form, it is necessary to use an inverter to convert the output voltage of these sources to the voltage required by consumers [8]- [11]. It should be noted that the required voltage of the DC link of single-phase and three-phase inverters is equal to 400 and 700 volts, respectively [12]- [14].…”

These days, DC-DC boost converters play an essential role in a variety of applications. Therefore, a variety of techniques were proposed in the literature to achieve the highest voltage gain. A large number of passive elements are typically used in high-voltage DC-DC converters. Increasing the order of the system would make modeling and controlling the output voltage of the converter more complex. This paper examines an ultra-lift DC–DC converter using a three-winding inductor and a super-lift construction in discontinuous conduction mode (DCM). This converter provides substantial voltage gain by utilizing the three-winding coupling inductor topology without increasing the duty cycle or passive circuit parts. Because the DCM operation mode occurs in the converter, it is necessary to investigate and analyze it. The DCM operation mode of an Ultra-Lift converter is examined in this study, and then simulation results are shown to validate the equations.
