Collection of publications on under-frequency load shedding protection

The number of publications in the field of under-frequency load shedding (UFLS) protection is rapidly increasing. This confirms that the topic is timely, but due to the large number of publications, it is easy to lose track of the prevailing concepts driving the latest technologies. To overcome this problem, researchers resort to subjective review articles in the literature in which individual authors attempt to systematically categorize UFLS algorithms according to their own understanding of a variety of approaches. Since this is not exactly a trivial task and is undoubtedly subject to personal interpretation, it is better to use specialized mathematical techniques for this purpose. Recently, it has been shown that clustering techniques and graph theory can be a useful tool for systematic literature reviews. If one decides to use such techniques to search for similarities between UFLS algorithms, one must first collect the relevant literature and extract important information. Therefore, this collection provides an Excel spreadsheet (.xlsx) of 381 publications on UFLS protection for the period 1954 to 2020, with the following information for each publication: i) authors, ii) title, iii) year of publication (journal, conference proceedings, dissertation, master thesis, bachelor thesis, other), iv) the source from which we obtained the publication, v) DOI (Digital Object Identifier), vi) extracted general features, and vii) extracted specific features. If the publication in the row can be assigned to the feature specified in column I3-BJ3, the corresponding cell contains the value "1". Otherwise, (i.e. if the feature specified in column I3-BJ3 cannot be assigned to the publication), the cell is empty. Detailed descriptions of the individual feature can be found in a Word document (.docx). The relevant literature was obtained from various open access journals, impact factor journals, repositories of various universities and archives of various electricity suppliers and transmission system operators.

低频减载（under-frequency load shedding, UFLS）保护领域的学术文献数量正快速增长。这表明该主题具有较高的时效性，但由于相关文献体量庞大，人们往往难以把握推动最新技术发展的主流研究理念。
为解决这一问题，现有研究多依赖文献中的主观性综述文章——由作者依据自身对各类研究方法的理解，对低频减载算法进行系统性分类。但这类工作绝非易事，且不可避免地受限于个人主观解读，因此更适宜采用专业化的数学方法完成此类梳理。
近期已有研究表明，聚类技术与图论可作为系统性文献综述的有效工具。若选择采用此类方法挖掘低频减载算法间的相似性，首先需收集相关文献并提取关键信息。
为此，本数据集收录了1954年至2020年间的381篇低频减载保护领域相关文献，并以.xlsx电子表格形式提供。每篇文献包含如下信息：
i) 作者信息；
ii) 文献标题；
iii) 发表年份（涵盖期刊论文、会议论文、博士学位论文、硕士学位论文、学士学位论文及其他类型文献）；
iv) 文献获取来源；
v) 数字对象标识符（Digital Object Identifier, DOI）；
vi) 提取的通用特征；
vii) 提取的专用特征。
若某篇文献可归属于第I3-BJ3列指定的特征，则对应单元格取值为"1"；反之，若无法将该特征匹配至该文献，则对应单元格留空。
各类特征的详细说明可参阅配套的.docx Word文档。
本次收录的相关文献来自各类开放获取期刊、带有影响因子的期刊、多所高校的知识库，以及多家电力供应商与输电系统运营商的档案库。
