For this end, Eggplant peel, Sour cherry waste and Red grape waste, which are unavoidable sources of food industry, have been used to prepare natural sensitizer. Extraction was done in water and ethanol and used for FTIR, UV–Vis and CV analysis. The extracts had a bathochromic shift in ethanol compared to water. The CV test results showed that the extracts prepared in water and ethanol are suitable for use in the DSSCs. DSSCs was prepared using titanium dioxide as a semiconductor, extracts in water and ethanol, and platinum and GO/MoS₂ nanocomposite in counter electrode. AM 1.5 light was chosen to study the photovoltaic performance and the prepared devices were evaluated. In this research, the effect of solvent and counter electrode on the DSSCs efficiency was investigated. The highest efficiency for the extract obtained from eggplant peel in ethanol and in the presence of platinum is about 1.49 %.</div></div>","PeriodicalId":56019,"journal":{"name":"Sustainable Energy Technologies and Assessments","volume":"72 ","pages":"Article 104066"},"PeriodicalIF":7.1,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142653556","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This purpose is fulfilled by minimizing the imported power from the transmission network resulting in maximization of renewables usage and minimization of power loss. The conducted approach is based on dynamic line rating (DLR) and dynamic network reconfiguration (DNR) as flexibility options. A convex formulation is employed to incorporate the objective function and constraints into a mixed-integer quadratically-constrained programming (MIQCP) model which is solved by global optimum solvers in GAMS. The proposed model is applied to the IEEE 33-bus system under different case studies, and the simulation results are analyzed. The obtained results indicate that the maximum scheduling of wind and PV units’ is fulfilled with the minimum energy losses.

This study addresses this need by utilizing advanced deep learning techniques and Geographical Information Systems (GIS) to estimate the energy output of wind turbines. Specifically, it focuses on predicting the energy production of both horizontal axis wind turbines (HAWTs) and vertical axis wind turbines (VAWTs) using a combination of Markov and Cellular Automata-Markov (CA-Markov) models, alongside deep learning methods such as long short-term memory (LSTM), LSTM-Wavelet, and Support Vector Regression (SVR). Additionally, the study evaluates the energy output of each turbine type, factoring in their construction costs within the study area. The analysis reveals significant variations in energy output over time, with maximum values increasing from 85,017 Wh in 2000 to 166,050 Wh in 2020 in the northern region, while minimum outputs also rose significantly. Projections for 2030 suggest that approximately 17% of the northern region experience a substantial increase in wind power potential. Among the forecasting methods, the LSTM-Wavelet hybrid model demonstrated superior accuracy, surpassing the 90% threshold, primarily due to its effective handling of data instability and noise reduction.
