Special Issue Information

Dear Colleagues,

Together with the serious environmental and energy problems we are experiencing in the 21st century, the desire to meet the increasing quality of life in the future makes it especially necessary to evaluate the sustainability approach. Sustainability adds "nature, environment, energy conservation, comfort" to the definition of solar systems, which is summarized as "robustness, functionality, aesthetics", and causes a change in their scope. Seasonal, daily and instantaneous changes in solar energy increase the importance of an effective use of energy. In the generation of electricity from solar energy, photovoltaics is environmentally friendly, has no moving parts and is easily integrated and converted from small powerful systems to large systems, meeting energy consumption demand in buildings and rural areas. Using the energy sourced from the sun in the form of electricity or thermal energy reduces our carbon emission contributions as a result of the solar energy obtained. Solar energy, which is the most preferred and widely used among renewable energies, is very important for a sustainable world. This Special Issue brings together the fundamental engineering tools and new technological breakthroughs in the development of state-of-the-art PV and solar systems for applications in addressing physical, economic and environmental issues.

The Guest Editors cordially invite submissions for this Sustainability Special Issue entitled “Advances in Renewable Energy: Photovoltaic System and Solar System”. Solar energy has huge potential as a source of electricity, space heating and cooling, water heating, energy storage, solar cooking, drying, distillation, industrial process heat, among others. Solar systems, especially photovoltaics, are an important renewable energy source that can provide green energy and reduce environmental damage. Advances in solar energy can be carried out throughout the entire chain, including design, production, tracking, control, and/or simulation. Photovoltaic/thermal systems are currently considered the best option due to their simultaneous production of heat and electricity. This Special Issue brings together the fundamental engineering tools and new technological breakthroughs in the development of state-of-the-art PV and solar systems for applications in addressing physical, economic and environmental issues. This Special Issue welcomes original proposals covering the most recent advances and focusing on improvements in photovoltaic systems, as well as different solar systems, for energy and resource efficiency techniques that minimize the amount of energy and materials utilized in the design and production of solar systems while ensuring high performance.

We look forward to your contribution in this Special Issue.

To achieve the goals of carbon peak and carbon neutrality, Xinjiang, as an autonomous region in China with large energy reserves, should adjust its energy development and vigorously develop new energy sources, such as photovoltaic (PV) power. This study utilized data spatiotemporal variation in solar radiation from 1984 to 2016 to verify that Xinjiang is suitable for the development of PV power generation. Then, the averages of the solar radiation, sunshine duration, and other data in the period after 2000 were used to assess the suitability of Xinjiang, based on spatial principal component analysis (SPCA). Finally, the theoretical power generation potential, fossil fuel reduction, and CO2 emissions reduction were estimated. The results are as follows: (1) In terms of temporal variation, the solar radiation in Xinjiang decreased (1984–2002), increased (2002–2009), and decreased again (2009–2016), but the fluctuations were not statistically significant. In terms of spatial distribution, the Kunlun Mountains in southern Xinjiang had the highest solar radiation during the span of the study period. Hami and Turpan, in eastern Xinjiang, had sufficiently high and stable solar radiation. (2) The area in Xinjiang classed as highly suitable for solar PV power generation is about 87,837 km2, which is mainly concentrated in eastern Xinjiang. (3) In the situation where the construction of PV power plants in Xinjiang is fully developed, the theoretical potential of annual solar PV power generation in Xinjiang is approximately 8.57 × 106 GWh. This is equivalent to 2.59 × 109 tce of coal. Furthermore, 6.58 × 109 t of CO2 emissions can be reduced. PV power generation potential is approximately 27 times the energy consumption of Xinjiang in 2020. Through the suitability assessment and calculations, we found that Xinjiang has significant potential for PV systems. Full article

The share of renewable energy resources in modern electrical power networks is increasing in order to meet environmental and technical targets. Consequently, energy researchers and power providers have been focusing on optimizing the integration of renewable energy into existing power grids. One of the most significant growing applications of renewable energy resources is residential photovoltaic (PV) systems; therefore, this paper discusses a new methodology to enhance the utilization of small-scale and medium-scale PV systems. For this purpose, this study proposes a user-friendly interface to help novice users optimally design their own PV projects with the highest possible utilization of the installed panels. Unlike the commercially available design tools, the proposed interface in this paper provides a higher degree-of-freedom computational process, as well as the option of improving the generated power quality, while maintaining the simplicity of the required tools and inputs. The proposed methodology mainly relies on a deep mathematical analysis considering different generation and consumption aspects, such as the load profile, time of usage, ambient temperature, PV system specifications and location. Furthermore, the mechanism of integrating a small portion of Energy Storage Systems (ESSs), to improve the quality of the extracted power, is also discussed in this study. The user interface provides the ability to estimate optimal ESS usage versus the estimated price when energy is urgently required. The case study was conducted in Riyadh, Saudi Arabia, and the results showed an essential improvement in the efficiency, solar fraction and power quality of the studied PV project, which can be extended to other home and distributed generation (DG) scales.

The impact of Partial Shading Conditions (PSCs) significantly influences the output of Photovoltaic Systems (PVSs). Under PSCs, the Power-Voltage (P-V) characteristic of the PVS unveils numerous power peaks, inclusive of local maxima and a global maximum. The latter represents the optimum power point. Traditional Maximum Power Point Tracking (MPPT) algorithms struggle to track the Global Maximum Power Point (GMPP). To address this, our study emphasizes the creation of a novel algorithm capable of identifying the GMPP. This approach combines the Cuckoo Search (CS) MPPT algorithm with an Integral Super-Twisting Sliding Mode Controller (STSMC) using their benefits to enhance the PVS performance under PSCs in terms of high efficiency, low power losses, and high-speed convergence towards the GMPP. The STSMC is a second-order Sliding Mode Control strategy that employs a continuous control action that attenuates the “chattering” phenomenon, caused when the first-order SMC technique is employed. Indeed, the proposed CS-STSMC-MPPT algorithm consists of two parts. The first one is based on the CS algorithm used for scanning the power-voltage curve to identify the GMPP, and subsequently generating the associated optimal voltage reference. The second part aims to track the voltage reference by manipulating the duty cycle of the boost converter. The proposed CS-STSMC-MPPT algorithm is featured by its strength against uncertainties and modeling errors. The obtained simulation results underline a high convergence speed and an excellent precision of the proposed method in identifying and tracking the GMPP with high efficiency under varying shading scenarios. For comparative purposes, this method is set against the hybrid CS-Proportional Integral Derivative, the conventional CS, the Particle Swarm Optimization, and the Perturb and Observe algorithms under different PSCs, including zero, weak, and severe shading. Simulation conducted in the Matlab/Simulink environment confirms the superior performance of the proposed CS-STSMC-MPPT algorithm in terms of precision, convergence speed, efficiency, and resilience.
