Abstract

This paper presents an innovative approach for protection coordination of directional over-current relays (DOCRs) in real distribution micro-grid via clustering and multi-objective optimization algorithm. A new clustering algorithm based on the network variation and two novel objective functions focused on main parameters of the power grids are employed to implement this study on the DOCRs. Moreover, this paper provides a new hybrid algorithm that integrates the goal attainment algorithm into the non-dominated sorting genetic algorithm III with the assistance of linear programming (LP). It is significant to highlight that there is no evidence of study on the protection coordination problem of DOCR (PCPD) with these novel objective functions, innovative clustering technique, and unique hybrid algorithm. It is crucial to point out that the PCPD has been effectively handled for two case studies, the NOAVARAN feeder and the IEEE 14 bus system, without any miss-coordination. Furthermore, the employment of the proposed hybrid algorithm achieves a substantial reduction of approximately 50–60 % in the operation time of all relays for this case study when compared to the other recommended mixed algorithms without utilizing linear programming.

定向过流继电器保护协调的优化程序：一种新方法

本文提出了一种基于聚类和多目标优化算法的实际配电微电网中定向过流继电器保护协调的创新方法。采用一种新的基于网络变化的聚类算法和两个新的以电网主要参数为中心的目标函数对docr进行了研究。此外，本文还提出了一种新的混合算法，该算法将目标实现算法集成到线性规划（LP）的非支配排序遗传算法III中。需要强调的是，目前还没有利用这些新的目标函数、创新的聚类技术和独特的混合算法来研究DOCR （PCPD）的保护协调问题。重要的是要指出，PCPD已经有效地处理了两个案例研究，NOAVARAN馈线和IEEE 14总线系统，没有任何协调失误。此外，与其他推荐的混合算法相比，在不使用线性规划的情况下，采用所提出的混合算法在本案例研究中实现了所有继电器操作时间的大幅减少，约为50 - 60%。
