配电网是新型电力系统建设中最为关键和最具活力的环节之一。面向日益复杂的配电网运行与控制问题,数字化转型已成为广受认可的发展思路。边缘计算为数字配电网中海量数据资源和物理资源的利用提供了有效手段,同时也将作为配电网多种业务功能在边缘侧的融合承载平台,推动配电网运行架构的发展变革。文中围绕边缘计算技术驱动下的配电网数字化转型问题,梳理了配电网边缘计算装置的关键技术需求;分析了配电网边缘计算的技术定位及由其所支撑构建的数字配电网技术架构,特别针对数字配电网运行问题,从集群化、分布式、灵活定义3个典型特征入手,围绕边缘侧集群自治、边-边协调控制、云-边协同运行等典型模式下的关键问题和技术研究方向进行了分析与探讨。
Distribution network have become one of the most critical and vigorous sectors in developing new power systems. Digital transformation is a widely recognized way to solve the complex operation and control problems of distribution networks. Edge computing is an effective means to utilize the massive data resources and physical resources in digital distribution networks. It also provides a comprehensive platform for implementing operation functions on the edge side
which promotes the development and transformation of the operation architecture for the distribution network. This paper focuses on the digital transformation issues of distribution networks driven by the edge computing technology. The essential technical requirements for edge computing devices in the distribution network are presented. The technical positioning of edge computing and its support to the technical architecture of digital distribution networks are analyzed. Especially aiming at the operation issues of digital distribution networks
starting from three typical features of clustering
distribution
and flexible definition
key issues and technical research directions are summarized and discussed
including typical modes such as edge-side cluster local control
edge-edge cooperative control and cloud-edge cooperative operation.
