“…To mitigate this drawback, redundant switching combination is proposed in this paper. MLI generally suffers from open circuit (OC) and short circuit (SC) faults across the power electronics switches [19]. A switch failure might harm the MLI healthy components in addition to impairing its usual function [10].…”

In this article, a fault-tolerant Packed U Cell MLI (FT-PUC-MLI) is presented, which utilizes two DC sources with nine main switches and eight redundant switches for creating 7-level across the output. The proposed topology uses phase disposition sinusoidal pulse width modulation (PD-SPWM) for the generation of gate signals. A detailed analysis of the proposed topology is done with respect to efficiency, power loss and total harmonics distortions (THD). A brief comparative analysis in terms of device count, total blocking voltage, post and pre fault efficiency, post and pre fault voltage levels is being done. The proposed topology can tolerate single-switch and multiple-switch failures, thus enabling it to be used for emergency loads. The proposed topology maintains a constant output voltage level in the post-fault period. The simulation of FT-PUC-MLI topology is carried out by using the MATLAB/SIMULINK platform with all possible switch fault combinations and real time simulation is also being done in OPAL RT 4510.

“…In recent years, renewable energy power generation has been widely used, among which photovoltaic power generation has developed rapidly [1][2][3] , as shown in Figure 1, which shows the growth curve of global photovoltaic installed capacity. With the increasing scale of photovoltaic access to the power grid, it has a greater and greater impact on the fluctuation of power grid output [4] .…”

“…Moreover, electricity generated by PV panels can also be stored in batteries or used directly from PV panels [6]. PV power production relies on different environmental factors impacting this absorption process, including humidity, dew, wind velocity, and dust accumulation [7]. The growth of bird droppings on the PV module surface can reduce the efficiency due to reduced transmittance [8].…”

Over the past few decades, the increased use of energy resources has led to an increase in electricity demand, which has compounded a constant shortage of nonrenewable energy resources. However, dust accumulation, humidity levels, temperature, and bird droppings can negatively affect the efficiency of PV systems. Bird droppings can cause shading areas and hot spots on PV cells, gradually reducing their performance. This study aims to investigate the impact of bird droppings and soiling on photovoltaic panels by developing an experimental setup. An experimental setup comprises two PV panels with monitoring and data logging sensors. During the cleaning process, one panel will be compared with a panel affected by bird droppings and soiling. The experiment was conducted for 25 days in a dusty and humid environment, affecting approximately 30% of the PV panel area by bird droppings. As a consequence, the panel's output decreased by 35%. In order to predict when the PV panel becomes completely opaque, resulting in zero power, after the experiment has been conducted, multiple linear regression techniques have been applied that show the whole panel will cover up in 82 days with bird droppings having a covering area of 128500 mm2. The experimental investigation concluded that bird dropping and soiling can significantly impact PV panel output degradation. Regular cleaning patterns will help to ensure efficient operation and maximize electricity generation.
