Considering the aforesaid fact, here, a smoothed pseudo-Wigner-Ville distribution (SPWVD) and stacked sparse autoencoder (SSA) based automated feature extraction technique is proposed for accurate detection of faults in grid connected solar PV systems. To this end, three phase current data of normal as well as different fault scenarios obtained from point of common coupling (PCC) were converted into direct (<i>d</i>) and quadrature (<i>q</i>) axis using extended Park’s vector approach. Then, the obtained <i>d</i>-axis (<i>I</i><sub><i>d</i></sub>) and <i>q</i>-axis (<i>I</i><sub><i>q</i></sub>) currents were converted to 2D time-frequency images using SPWVD. The converted time-frequency spectrum of the normal as well as faulty current data were used as inputs to the proposed SSA model for deep feature extraction. After extraction of deep features using SSA, analysis of variance (ANOVA) test and false discovery rate (FDR) correction was employed to select the most discriminative features. The feature selection was followed by classification using machine learning classifiers. It has been observed that the proposed technique achieved mean fault recognition accuracy of 98.79 and 97.56% for <i>d</i>-axis and <i>q</i>-axis currents respectively, respectively. The present approach can be used for accurate diagnosis of faults in grid connected solar PV systems.</p>","PeriodicalId":475,"journal":{"name":"Applied Solar Energy","volume":null,"pages":null},"PeriodicalIF":1.204,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141776440","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These power stations are typically located in windy and sandy environments, the strong winds can lead to deflection, deformation, or even collapse of heliostats, significantly impacting the light-gathering efficiency of the entire power generation system and causing substantial economic losses. Therefore, understanding the influence of wind on heliostats and their surroundings is crucial for designing wind-resistant heliostat structures, optimizing their layout, and enhancing power generation efficiency. This research employs computational wind engineering (CWE) for the study of wind-related phenomena in heliostat arrays under varying spatial conditions. This research employs three mathematical models for inlet boundary conditions in wind engineering, distinct from empirical expressions. Corresponding user-defined function (UDF) programs simulate conditions consistent with wind tunnel tests. The analysis aids in determining entrance boundary conditions tailored to the geomorphological characteristics of heliostats, laying the foundation for subsequent 3D numerical wind tunnel construction and simulation. It calculates wind load coefficients under various spatial positions, determining the maximum force coefficients for each component and identifying optimal deflection positions under adverse wind conditions. Based on heliostat structure dimensions and radiation grid layouts, the research calculates radial and circumferential distances that ensure no mechanical collisions or shielding losses occur between adjacent heliostats. This information aids in determining optimal heliostat spacing.</p>","PeriodicalId":475,"journal":{"name":"Applied Solar Energy","volume":null,"pages":null},"PeriodicalIF":1.204,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141776442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main focus is on the number of clear, partly cloudy and cloudy days, as well as the number of days without sun. It was revealed that the largest number of clear days per year was recorded at the Boz weather station (168 days), while the smallest was in Fergana (112 days). As for partly cloudy days, the maximum number was recorded at Yubileinaya weather station (81 days). The maximum number of cloudy days was observed at the Fergana weather station (186 days). Based on the results and the annual dynamics of clear days, the locations in the region of Boz and Kokand weather stations appear to be the most suitable for installing solar power plants due to their potential for the efficient use of sunlight. Also, despite of the summer potential, in winter the number of clear days decreases, which can affect the performance of solar power plants. This is especially true for the Fergana weather station, where the number of cloudy days in December and January can reach 23. On average, the Andijan, Boz, Yubileinaya, Pap, Kokand and Kuva weather stations, observe 3–4 consecutive days without sun per year. At the Fergana weather station, this value is 4–6 days.

Notice that the level of radiation acts on the opposite of two important factors. The FF was at its lowest value in summer, but the efficiency is at its maximum value.

Now, based on new technology and research, photovoltaic power generation is also enjoying the reliable and efficient technology advantage. By enhancing the efficiency of photovoltaic power generation, the economic gap (per unit energy cost) between conventional and renewable one can be mitigated, by generating more energy during available sunny-times. The efficiency of the photovoltaic cell decreases drastically with an increase in module temperature.

Despite its benefits, the deployment of photovoltaic (PV) modules generates significant waste, thereby posing a major environmental challenge. This study explores several recycling techniques, including physical, thermal, and chemical methods, that could be employed to manage solar panel waste. An in-depth analysis of separation techniques presently employed and underdevelopment was studied and compared to determine the physical treatment necessary for the separation of glass and aluminium. Extraction of rare earth metals cadmium, copper and tellurium requires chemical treatments using organic and inorganic solvents along with thermal treatment at 500–600°C to remove the EVA polymer. Recovery of silicon wafers and rare metals through various metal extraction processes is further examined. Europe was concluded as a frontrunner in solar waste management policies after analysis of the governmental policies of developed and developing nations of the world. The circular economy model developed portrayed a systematic approach for the removal of different components of a solar panel and reintegration into the manufacturing process.

This study proposes an approach to mitigate the soiling, dust and assess the PV module performance under IEC 60891 by using of based-brush and based-water cleaning methods (CBB and CBW), which can significantly increase power generation and reduce the cost of operation and maintenance. Moreover, the CBB and CBW cleaning types help to improve the performance of PV modules. The cleaning factor shows that the overall electrical output power is approximately 3.09%, with an average value of 1.61% in cleaning based-brush and 1.49% in cleaning-based water, the CBB improve the total output power with 52% and CBW with 58%.

Therefore, a regular wet or dry cleaning of PV modules surface is essentially needed and the combination between the two methods is important to attempt the minimum costs and maximum power.
