“…To observe that the algorithms can control the MPPT in a boost converter (or other DC-DC converter), we fed a local load or DC bus of a voltage source inverter. Here, the inverter regulates the DC bus voltage through the power control loop in an almost constant value [39]. A common and reliable grid-connected approach is summarized in Figure 1.…”

“…The PV model was built according to [40], i.e., as a voltage-dependent current-source in conjunction with Cin. The MPPT block controls the DC-DC converter, whereas Cv(s) and Ci(s) controls the DC-AC converter for proper power injection in the grid [39]. If only the DC-DC boost converter is adopted, the designer should consider a resistive load (RL) to produce the desired output voltage (VBUS) at the maximum power point in order to optimize the controllers' design.…”

“…However, no design procedure could project such algorithms, i.e., as control systems. Additionally, some authors [9,39] adopted PI controllers in the overall converter control system, yet these compensators focused on controlling the power converter, i.e., controlling the DC bus voltage, the output grid current, and the input voltage not inside the MPPT algorithm.…”

This paper presents a novel complete design procedure to convert a maximum power point tracking (MPPT) algorithm into a control system. The MPPT algorithm can be tuned by employing any control system design. In this paper, we adopted Bode diagrams using the criteria of module and phase as the power electronics specialists are habituated with such concepts. The MPPT control transfer functions were derived using the average state equations and small-signal analysis. The control loops were derived for power and voltage control loops. The design procedure was applied to the well-known perturb and observe (P&O) and incremental conductance (IC) algorithms, returning the P&O based on PI and IC based on PI algorithms. Such algorithms were evaluated through simulation and experimental results. Additionally, we showed that the proposed design methodology can optimize energy harvesting, allowing algorithms to have outstanding tracking factors (above 99%) and adaptability characteristics.

“…Thus, there are many research and development activities that seek to further increase their conversion efficiency through materials science, with the main advances being listed in NREL (2022), since 1976. In addition to studies on PV technology itself, many researches focus on inverter devices in order to increase their efficiency and performance, such as maximum power point tracking techniques (De Brito et al, 2019;Njomo et al, 2021).…”

The photovoltaic module position related to the Sun greatly affects its power production due to the latter being dependent on the irradiation incidence. One-axis trackers are used to physically move the modules so they follow the Sun's daily trajectory and hence increase energy harvesting. This paper investigates how relevant the actuating angular step of a one-axis tracker is concerning the daily and annual energy photovoltaic energy production. An east-west rotational axis with a fixed tilt angle is experimentally analyzed with four different steps: 2°, 5°, 10°, and 30°angular movements. Results are obtained over 1 year and compared to the energy production of a fixed mount photovoltaic module. Only a maximum difference of 1.68% is observed between the tracking strategies. The sky's condition is also considered, where clear or mostly clear days (60.9% of the analyzed period) contributed to 78.8% of energy production.
