基于文献计量学的微电网技术研究进展及前沿分析

Research Progress and Frontier Analysis of Microgrid Technology Based on Bibliometrics

可再生能源具有很强的随机性和波动性,给分布式能源系统的开发利用带来了很大的挑战。微电网的提出旨在实现分布式电源的灵活、高效应用,解决数量庞大、形式多样的分布式电源并网问题。微电网的研究涉及到复杂的技术问题,因而对微电网系统的研究很多都是局部的,即使有从整个系统出发的相关文献,也只是粗略介绍。而文献计量分析可以定量地揭示某一学术领域的发展历程、研究重点以及未来的研究方向。采用文献计量学方法,基于WoS核心合集已发表的文献,通过可视化软件CiteSpace绘制知识图谱。图谱分析结果表明,从2012年开始,与微电网领域相关的论文逐渐增加,其中中国、美国、伊朗、印度、丹麦等国家发文量最多,而热门研究机构主要是各国的高校;通过对文献共被引以及关键词共现分析可知,前期的研究主要集中在基础技术上,如微电网模型的建立、控制策略、稳定性研究、优化方法、管理方法等;通过关键词突现分析,得到今后的研究热点,包括智能交互能源、模型预测控制、生命周期评估、能源领域的区块链技术和数据注入攻击等。

Renewable energy is highly stochastic and volatile,bringing great challenges to the development and utilization of distributed energy system.Microgrid is proposed to realize the flexible and efficient application of distributed power and solve the grid connection problem of a large number and various forms of distributed power.The research on microgrid involves complex technical issues,so many studies on microgrid system are partial.Relevant literature on the whole system,if any,only gives a rough introduction.Bibliometric analysis can quantitatively reveal the development history,research focus and future research direction of an academic field.Using the bibliometric method,the knowledge map is drawn by visualization software CiteSpace based on the published literature from WoS core collection.The results of the mapping analysis show that the number of papers related to microgrid has gradually increased since 2012.Among them,China,the United States,Iran,India and Denmark have published the most papers,and the popular research institutions are mainly universities around the world.The literature co-citation and keyword co-occurrence analysis shows that the preliminary research mainly focuses on basic technologies such as the establishment of microgrid model,control strategy,stability research,optimization method and management method.Through keyword emergence analysis,future research hotspots including intelligent interactive energy,model predictive control,life cycle assessment,block chain technology in the energy field and data injection attacks are obtained.
