Hybrid solar-hydrogen systems (HSHSs), which combine solar energy harvesting and hydrogen production, have excellent prosepects to address challenges related to renewable energy generation, storage, and usage. This article presents an overview of the research on the technical and economic feasibility of HSHSs, aimed at comprehensively articulating their current state, notable advancements, and future research directions. It begins by elucidating solar energy principles and conversion methods and emphasizing the potential of solar energy for hydrogen production. This study then explores the definitions, components, and synergistic integration of HSHSs. Optimized energy conversion and storage methods for efficient hydrogen production and storage are also highlighted. This study reviews the techniques employed for techno-economic evaluations over the last six years, addressing challenges such as the intermittency of solar energy and the efficiency of hydrogen production technologies. This review of the ongoing research provides helpful insights into the technological and economic feasibility of HSHSs. This underscores the necessity of continuous research and development efforts to overcome existing challenges and unlock their full potential. These systems can play a vital role in achieving a cleaner and more resilient energy future by optimizing the system performance, reducing costs, and fostering supportive policy frameworks.","PeriodicalId":100648,"journal":{"name":"iEnergy","volume":"3 1","pages":"28-38"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10488348","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140340084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Simulating power systems' behaviors during cascading failures is of great importance to comprehend how failures originate and propagate, as well as to develop effective preventive and mitigative control strategies. The intricate mechanism of cascading failures, characterized by multi-timescale dynamics, presents exceptional challenges for their simulations. This paper provides a comprehensive review of simulation models for cascading failures, providing a systematic categorization and a comparison of these models.

Thus, an accurate method needs to be developed to estimate the battery state of health (SOH). Existing SOH estimation methods in recent literature mainly fall into two categories: model-based and datadriven methods. Model-based methods attempt to expand the original battery model by taking into account various factors affecting the battery degradation. Data-driven methods aim to characterize the relation between battery SOH and various health indicators by machine learning. Once the training process has been completed, such data-driven methods are less complex to implement than model-based methods, making them more promising for practical applications.","PeriodicalId":100648,"journal":{"name":"iEnergy","volume":"2 4","pages":"257-257"},"PeriodicalIF":0.0,"publicationDate":"2023-12-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10376445","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139060264","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The power supply and signal acquisition units of the sensor may be coupled with ground wire interference, which could result in reduced measurement accuracy. Moreover, this problem is often ignored by researchers. This paper investigated the origin of ground coupling interference in electric field sensors and its impact on measurement accuracy. A miniature undistorted electric field sensor with wireless transmission was compared with existing D-dot, microelectromechanical systems (MEMS), and optical sensors. The results indicate that MEMS and D-dot exhibit diminished accuracy in measuring electric fields under uniform conditions, owing to interference from ground wires. In the case of transmission lines with non-uniform conditions, the wireless sensor exhibited a measurement error of 5%, whereas the optical sensor showed an error rate of approximately 8%. However, the D-dot sensor displayed a measurement error exceeding 50%, whereas the MEMS sensor yielded an error as high as 150%. This means that the wireless sensor isolates the ground-coupled interference signal and realizes the distortion-free measurement of the electric field. The wireless sensors will find extensive applications in new power systems for intelligent equipment status perception, fault warning, and other scenarios.","PeriodicalId":100648,"journal":{"name":"iEnergy","volume":"2 4","pages":"314-322"},"PeriodicalIF":0.0,"publicationDate":"2023-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10365719","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139060081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The key idea behind the HEM is to convert the task of solving complex algebraic equations into a series expansion involving one or multiple embedded complex variables. This transformation empowers the utilization of complex analysis tools to tackle the original problem effectively. Since the 2010s, the HEM has been applied to steady-state and dynamic problems in power systems and has shown superior convergence and robustness compared to traditional numerical methods. This paper provides a comprehensive review on the diverse applications of the HEM and its variants reported by the literature in the past decade.

To ensure the safe and stable operation of ultra-high voltage (UHV) transmission equipment, this work reports on the principles and preliminary results of using electroluminescence (EL)-based photon counting (PC) methods for early detection of micro-defects in GIS/GIL insulation spacer. In this study, the impact of voltage, gas pressure, and gas composition on the photon response of insulation is examined. Furthermore, the corresponding relationship between defect status and photon response characteristics is explored, along with the discussion of the EL mechanism and its evolution induced by defects. The research results demonstrate that PC measurement exhibits high sensitivity to variations in millimeter-scale defect size, position, and morphology at lower electric fields before partial discharge (PD) initiation. With this regard, this paper reveals promising prospects for the early detection of micro-defects in UHV transmission equipment using PC measurement-based methods.","PeriodicalId":100648,"journal":{"name":"iEnergy","volume":"2 4","pages":"258-263"},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ieeexplore.ieee.org/stamp/stamp.jsp?tp=&arnumber=10352432","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139060265","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
