“…Based on the configuration of the photovoltaic array, the shading effect on the specific PV system can be studied. An efficient and unifying approach to investigating and determining the behavior of PV modules, a maximum power point tracking system can be used together with a specific algorithm such as fuzzy logic, disturbance and observation, buck converter, incremental inductance, i.e., [39][40][41][42][43][44].…”

The present work proposes an enhanced method of investigation and optimization photovoltaic (PV) modules by approaching and using MPPT (Maximum Power Point Tracking) technique to improve their output power. The performance of the PV panels is strongly influenced by the operating conditions, especially regarding the solar irradiance, temperature, configuration, and the shading (due to a passing cloud or neighboring buildings); all these cause, both on energy conversion loss, and further on non-linearity of the I-V characteristics. From this reason, the present study could have a high relevance based on the improvement of the performances (including the efficiency) of the shaded photovoltaic panels and would quantify the impact of a complex approach represented by numerical modeling and experimental validation. For a better understanding of these issues determined by partial shading, and improvement of MPP tracking, it is required to study the behavior of individual panels. For the best accuracy of the implemented models a comparative analysis and optimized method of the PV modules was considered based on: (1) the influence of temperature and solar irradiance and behavior of the PV modules in partial shading conditions; (2) a comparison between the optimized output power of four algorithms (FLC—Fuzzy Logic Controller, P&O—Perturb and Observe, IncCond—Incremental Conductance and RC Ripple Correlation) and the selection of the best one (FLC); (3) discussion of customized/improved fuzzy logic controller (FLC) algorithm on five operation points introduced in order to increase PV module efficiency under fluctuating weather conditions and rapidly changing uncertainties. Furthermore, the FLC provides a set of rules useful for predicting the current-voltage behavior and the maximum power points of shaded photovoltaic modules. This FLC algorithm was implemented in a specialized software, namely MATLAB/Simulink. The authors highlighted the development and implementation of a numerical simulation model for an advanced PV module to determine its behavior under different operating conditions and improve its performance. The essence of the authors’ research and the motivation of this work is described. The authors were able to stabilize and improve the output performance of the PV module. The results concerning the shading effect as well as the shading patterns were developed, demonstrated, and experimentally validated. These results could be applied for the actual photovoltaic installations, respectively complex stand-alone or grid-connected photovoltaic systems.

“…Both the electrical efficiency and, hence, the power output of a PV module depend linearly on the operating temperature decreasing. It has been reported that PV module power output decreases by 0.4 -0.5% for 1°C increase in temperature above the standard operating temperature, depending on the temperature coefficient of the power of the module [17].…”

Vietnam has been regarded as a country with immense opportunities for renewable energy in general and for the development of solar and wind power in particular. Existing policy targets and mechanisms have been taken into practice with an aim to encourage this promising field and increase the proportion of electricity generated from these two power sources. However, the potential of these technologies has yet to be fully utilized, with approximately seven percentage of the nation's energy mix coming from renewable energy sources, according to Vietnam Electricity annual report. Conventional energy sources (coal, natural gas, and hydropower) still play a significant role in Vietnam's total primary energy supply. In this research, evaluation of the potential of renewable energy sources, emphasizing on solar power energy with its opportunities and challenges in Vietnam's power energy sector will be discussed. The main idea of this paper is to provide an overview of methodologies used for assessing photovoltaic potential and estimation of energy production from a given photovoltaic installation site. This can be a recommendation information of input indicators for investors, planners, and developers to strategize further decisions for the expansion of renewable power energy sources, especially photovoltaic systems in the chosen region.

“…However, under direct sunlight, the cell temperature becomes around 30 • C higher than the ambient temperature. PV panel efficiency is affected negatively by temperature increase [59,60]. It is obvious from the simulation results that the variation of the annual average ambient temperature from −20% to +20% of the basic value results in reducing the renewable fraction from 55.8% to 52.7%, and this leads to an increase in the NPC from USD 33,206 to USD 34,255.…”

Hybrid energy systems (HESs) consisting of both conventional and renewable energy sources can help to drastically reduce fossil fuel utilization and greenhouse gas emissions. The optimal design of HESs requires a suitable control strategy to realize the design, technical, economic, and environmental objectives. The aim of this study is to investigate the optimum design of a grid-connected PV/battery HES that can address the load requirements of a residential house in Iraq. The MATLAB Link in the HOMER software was used to develop a new dispatch strategy that predicts the upcoming solar production and electricity demand. A comparison of the modified strategy with the default strategies, including load following and cycle charging in HOMER, is carried out by considering the techno-economic and environmental perspectives. According to optimization studies, the modified strategy results in the best performance with the least net present cost (USD 33,747), unmet load (87 kWh/year), grid purchases (6188 kWh/year), and CO2 emission (3913 kg/year). Finally, the sensitivity analysis was performed on various critical parameters, which are found to affect the optimum results on different scales. Taking into consideration the recent advocacy efforts aimed at achieving the sustainable development targets, the models proposed in this paper can be used for a similar system design and operation planning that allow a shift to more efficient dispatch strategies of HESs.
