“…For PV panels, due to the absorption of solar energy, the temperature may be too high; this is only one of the reasons for the increase in the temperature of PV panels [70], which also reduces the power generation efficiency of PV panels. A wind load accelerates the cooling of PV panels, thereby reducing the cell's temperature and increasing the power generation efficiency for PV power generation.…”

(1) Background: As environmental issues gain more attention, switching from conventional energy has become a recurring theme. This has led to the widespread development of photovoltaic (PV) power generation systems. PV supports, which support PV power generation systems, are extremely vulnerable to wind loads. For sustainable development, corresponding wind load research should be carried out on PV supports. (2) Methods: First, the effects of several variables, including the body-type coefficient, wind direction angle, and panel inclination angle, on the wind loads of PV supports are discussed. Secondly, the wind-induced vibration of PV supports is studied. Finally, the calculation method of the wind load on PV supports is summarized. (3) Conclusions: According to the particularity of the PV support structure, the impact of different factors on the PV support’s wind load should be comprehensively considered, and a more accurate method should be adopted to evaluate and calculate the wind load to lessen the damage that a PV support’s wind-induced vibration causes, improve the force safety of PV supports, and thereby enhance the power generation efficiency of PV systems.

“…Recently, a lot of attention has been devoted to obtaining energy from renewable energy sources (RES). The growing interest in the aforementioned methods of electricity generation is accompanied by the problem of its storage [3][4][5]. In the case of energy systems based on RES, in which energy sources are characterized by high instability depending on weather conditions, the use of the appropriate energy storage solutions is of the utmost importance.…”

“…However, this achievement must be completed with a limited number of elements; thus, a new controlling state for the H-bridge switches was completed. Similar to other MLI topologies, the proposed inverter is useful for grid-connected photovoltaic (PV) systems [26][27][28][29][30][31]. Figure 1 presents a simple PV system in which the inverter is essential to transfer the DC voltage to AC voltage and make it more suitable for a grid utilities application [32].…”

Optimization of a Multilevel Inverter Design Used for Photovoltaic Systems under Variable Switching Controllers

Among multilevel inverters (MLIs), two-level inverters are the most common. However, this inverter type cannot maintain total harmonic distortion (THD) due to its limited number of levels. Reductions in THD are inversely proportional to the number of levels where increased output occurs in diverse ways, and the use of fewer components with low harmonic distortion is necessary for such reductions. This work proposes a seven-level (7L) MLI design with a small number of components and low harmonic distortion. The proposed MLI is combined with switched capacitor (SC) cells to promote output levels and at the same time to boost the input voltage. The connections between the capacitor and the source are based on the series to parallel topology, where the charging and discharging of the SC cells are caused by fluctuations in their connection. The output of the SC cell is combined with an H-bridge inverter controlled by a proposed PWM controller. The simulation result of the SC 7L inverter was completed using LTspice software. A comparison of the proposed topology with that of other current MLI led to better validation results. The proposed design shows a reduction in the THD with fewer components. The cost and size of the proposed inverter is minimal due to the smaller number of components. Ohmic load and inductive ohmic load were used as loads for the system.
