Reserving some active power in PV systems is crucial to manage the problem of low inertia. In this paper, we critically analyse and compare the performances of several active power reserve and frequency regulation techniques for PV systems. The discussed techniques do not use energy storage devices and are aimed at enabling the inertial capabilities of PV systems. These techniques are broadly classified according to the shading conditions and methodologies adopted for reserve generation. In this paper, we closely investigate different deloading techniques used in PV systems. In deloading, PV systems are operated at a voltage distant from the maximum power point. Further, we also address the effectiveness and suitability of the aforementioned techniques under different operating conditions. Through this review paper, we aim to provide a one-stop reference for PV researchers to select appropriately from the available reserve techniques for designing flexible DC–DC controls for PV systems.","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134931104","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review article discusses the scope and potential of FSPV and CTSPV, an ambitious plan, and various upcoming FSPV projects in India. The review focuses on different degradation modes, failure mechanisms, characterization techniques and distinct factors influencing the degradation of SPVs operating in tropical climates. It was explored that potential induced degradation and materialistic degradation have a significant impact on the performance of SPV. The paper provides an overview of the test procedures outlined in IEC-61215 and IEC-62804 that pertain to SPV performance under hot and humid conditions. Additionally, it presents a comprehensive review of the various methodologies adopted for accelerated damp heat testing to predict the life of PV systems in such conditions, and their significant quantitative and visual outcomes is elucidated. Also, till date, no simulation tool has been available to assess the long-term performance of SPV in a humid environment. As this energy generation technique is still in its infancy, this study will help many researchers and solar power developers recognize the impact of elevated and prolonged exposure to temperature and humidity on generation, degradation, and mode of failure for different SPV technologies.","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135323826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The focus here is on the variation of turbulent minimum ignition energies (MIE</span>_T) against laminar MIE (MIE_L<span>) over a wide range of r.m.s. turbulence fluctuation velocity (</span><em>u</em>ʹ) alongside effects of the spark gap between electrodes, Lewis number, and some other parameters on MIE. Two distinguishable spark ignition transitions are discussed. (1) A monotonic <em>MIE transition</em>, where MIE_L sets the lower bound, marks a critical <em>u</em>ʹ_c between linear and exponential increase in MIE_T with <em>u</em>ʹ increased. (2) A non-monotonic <em>MIE transition</em>, where the lower bound is to be set by a MIE_T at some <em>u</em>ʹ_c, stems from a great influence of Lewis number and spark gap despite turbulence. At sufficiently large Lewis number &gt;&gt; 1 and small spark gap (typically less than 1 mm), turbulence facilitated ignition (<em>TFI</em>), where MIE_T &lt; MIE_L, occurs; then MIE_T increases rapidly at larger <em>u</em>ʹ &gt; <em>u</em>ʹ_c<span> because turbulence re-asserts its dominating role.

So far, carbon black supported platinum (Pt/C) and its alloys are still the most practical and best-performing type of catalysts. However, the scarcity of Pt is highly challenging and the high price of commercial catalyst will continue to drive up the cost of both PEMFCs and AEMFCs. Moreover, the traditional carbon black support is susceptible to corrosion especially under electrochemical operation, itself inactive for ORR and weakly binding with Pt-based nanoparticles<span><span><span>. In this review, the advanced carbons synthesized by various template methods, including hard-template, soft-template, self-template and combined-template, are systematically evaluated as low-Pt catalyst supports and non-noble catalysts. For the templates-induced carbon-based catalysts, this review presents a comprehensive overview on the carbon supported low-Pt catalysts from aspect of composition, size and shape control as well as the non-noble carbon catalysts such as transition metal-nitrogen-carbons, metal-free carbons and defective carbons. Furthermore, this review also summarizes the applications of low/non-Pt carbon-based catalysts base on the template-induce advanced carbons at the cathodes of PEMFCs and AEMFCs. Overall, the templates-induced carbons can show some perfect attributes including ordered morphology, reasonable pore structure, high conductivity and surface area, </span>good corrosion resistance and mechanical property, as well as strong metal–support interaction.

To address these issues, this review also summarizes some effective strategies, such as employing the easily removed hard/soft-templates, developing the advantageous self-templates, enhancing the metal–support interaction by formation of chemical binds, etc. In conclusion, this review provides an effective guide for the construction of template-induced advanced carbons and carbon-based low/non-Pt catalysts with analysis of technical challenges in the development of ORR </span>electrocatalysts for both PEMFCs and AEMFCs, and also proposes several future research directions for overcoming the challenges towards practical applications.</span></span></p></div>","PeriodicalId":410,"journal":{"name":"Progress in Energy and Combustion Science","volume":"98 ","pages":"Article 101101"},"PeriodicalIF":29.5,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"1886067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
