摘要
以光伏、风电为代表的大规模分布式电源并网对电网的安全可靠运行带来了挑战,基于物联网分层协同的设计构想成为大规模分布式电源集群并网调控技术发展的新方向。基于“云、管、边、端”的物联网设计理念,探讨了其应用于分布式电源集群调控中的体系架构和关键技术。首先对云管边端物联网设计理念下分布式电源集群调控的体系架构进行了阐述,分析了架构各层级之间的关联关系,同时对云管边端各环节的具体功能结构进行了重点梳理和探讨。进而,按照该架构层级对集群动态划分技术、集群协调优化技术、多源数据融合与处理技术、集群等值建模方法,以及集群内部的自治运行等关键技术进行了综述,并对需要深层次开展研究的技术方向进行了展望,以期实现规模化分布式电源的高效消纳并提高其参与电网调控运行的互动能力。
The grid connection of large-scale distributed generations represented by photovoltaic and wind power brings challenges to the safe and reliable operation of the power grid.The idea of hierarchical coordination design based on the Internet of Things becomes the novel direction of large-scale distributed generations cluster technology development.This paper discusses the architecture and key technologies of the scheduling and control of distributed generations clusters according to the idea of“cloud-network-edge-terminal”design.Firstly,the grid-connected architecture of the distributed generations clusters under the concept of“cloudnetwork-edge-terminal”design is expounded.The relationships between each level are then analyzed,and the specific functions of each link of the“cloud-network-edge-terminal”design are combed and discussed emphatically.Next,the key technologies under the framework are summarized including the dynamic division and the coordinated optimization of clusters,the multi-source data fusion and processing,the clusters equivalent modeling,and the autonomous operation within the clusters,and the further research technical directions are discussed.This design can achieve the efficient consumption of large-scale distributed generations and improve the ability to participate in the scheduling control of the power grid interaction.
