摘要

微电网是随着分布式发电机的日益普及而发展起来的一个概念。随着分布式能源在微电网中的渗透程度越来越高,以及先进的控制和通信技术,传统的微电网概念正在向微电网集群的概念过渡。它将配电系统分解为多个相互连接的微电网,有效地减少了电压上升、谐波、功率因数差、反向潮流和常规保护方案失效等问题。微电网集群有效地协调了微电网与主电网之间的电力共享,提高了用电场所配电网的稳定性、可靠性和效率。尽管微电网集群对消费者和电力公司有明显的好处,但在采用微电网集群概念之前仍有一些挑战需要克服。本文旨在批判性地回顾微电网集群设计方面的挑战。基于互联布局将多微电网分类为不同的架构,对微电网集群和多微电网保护方面的控制技术进行了评估,强调了未来可能研究的领域,以改善微电网集群的运营方面。

Design and protection of microgrid clusters: A comprehensive review
A microgrid is a concept that has been developed with the increasing penetration of distributed generators. With the increasing penetration of distributed energy resources in the microgrids, along with advanced control and communication technologies, the traditional microgrid concept is being transited towards the concept of microgrid clustering. It decomposes the distribution system into several interconnected microgrids, effectively reducing problems such as voltage rise, harmonics, poor power factor, reverse power flow and failure of the conventional protection schemes. Microgrid clusters effectively coordinate power sharing among microgrids and the main grid, improving the stability, reliability and efficiency of the distribution network at the consumption premises. Despite the evident benefits of microgrid clusters to the consumers and the electrical utility, there are challenges to overcome before adopting the microgrid cluster concept. This paper is aimed at critically reviewing the challenges in design aspects of microgrid clustering. Categorization of multi-microgrids into different architectures based on the layout of the interconnections, evaluation of reported control techniques in microgrid clustering and multi-microgrid protection aspects are presented, highlighting the possible areas of future research that would improve the operational aspects of microgrid clusters.
