Forthcoming and Online First Articles

International Journal of Renewable Energy Technology

International Journal of Renewable Energy Technology (IJRET)

Forthcoming articles have been peer-reviewed and accepted for publication but are pending final changes, are not yet published and may not appear here in their final order of publication until they are assigned to issues. Therefore, the content conforms to our standards but the presentation (e.g. typesetting and proof-reading) is not necessarily up to the Inderscience standard. Additionally, titles, authors, abstracts and keywords may change before publication. Articles will not be published until the final proofs are validated by their authors.

Forthcoming articles must be purchased for the purposes of research, teaching and private study only. These articles can be cited using the expression "in press". For example: Smith, J. (in press). Article Title. Journal Title.

Online First articles are published online here, before they appear in a journal issue. Online First articles are fully citeable, complete with a DOI. They can be cited, read, and downloaded. Online First articles are published as Open Access (OA) articles to make the latest research available as early as possible.

Open AccessArticles marked with this Open Access icon are Online First articles. They are freely available and openly accessible to all without any restriction except the ones stated in their respective CC licenses.

  • Experimental investigation and optimisation of biodiesel production process   Order a copy of this article
    by Arun Singh, Manjoo Rani, Saty Dev, Pushpendra Yadav 
    Abstract: The general conditions such as increasing energy demand, high dependence on oil, severe environmental damage and the extinction of oil reserves have awakened the desire for renewable energy sources. Biodiesel is an environmentally friendly replacement for petroleum products. In this study, transesterification of Pongamia oil and algae oil was performed to produce a biodiesel blend that meets human needs in a sustainable environment. Study on direct transesterification of high free fatty acid (FFA) Pongamia oils mixed with low FFA algae oil at low temperature. Influence of process parameters, namely reaction time, catalyst amount and methanol/oil ratio, on biodiesel yield, which is analyzed and optimised by hybrid statistical methods. Experimental validation of predicted parameters such as reaction time 60.001 minutes, catalyst amount 7.097 E-5 kg and methanol-oil ratio 57.076 gave an accuracy of 99.98%. The test plant was designed considering rural operating conditions and suitable for biodiesel production for small businesses.
    Keywords: biodiesel; pongamia oil; algae oil; transesterification; process optimisation.

  • Emerging techniques in islanding detection for microgrids: an extensive review   Order a copy of this article
    by Nirali Upadhyay, Sweta Shah, Vipul Upadhyay 
    Abstract: Use of distributed generation (DG) as renewable energy at distribution level is substantially increased to fulfil increasing demand. However, the penetration of different renewable energy sources as DG increases new challenges and concerns like working of micro grid under islanded and grid connected mode. Also detecting intentional and unintentional islanding as per IEEE standards is a major challenge. Unintentional islanding give rise to several grid protection issues like stability of grid and safety of worker. To overcome these issues and for satisfactory operation of micro grid many islanding detection techniques have been developed by researchers. This paper presents a comparative review of several islanding detection schemes with basic focus on its working algorithm, merits and demerits, on detection zone and speed. The outcome is, there is no perfect detection technique developed yet. Some of these techniques or integration of them are to be applied practically to specific distributed source and grid structure.
    Keywords: micro grid; islanding detection methods; distributed generation; non-detection zone; NDZ; intentional islanding; unintentional islanding.
