摘要
新型配电网大量接入分布式能源,成为构建新型电力系统的主战场。传统配电网的竖井式通信架构,及其101/104通信协议已不能满足新型配电网的云-边、边-边通信需求,亟需提升配电网智能终端的信息采集与汇聚、边缘计算、即插即用能力,并寻求满足新型配电网通信需求的通信方案,为新型配电网的可靠运行提供底层技术架构支撑。为此提出了新型配电系统智能终端分布式控制通信方案。首先提出更高效的、允许分布式智能节点相互交互的分布式协调控制架构;其次使用IEC 61850建模技术对智能终端建模,并遵循IEC 62361标准,解决CIM模型与IEC 61850模型融合的问题;最后提出通过高可靠性、高实时性的物联网通信协议DDS来实现模型在协议上的映射。基于所提出的通信方案,智能终端具备即插即用能力,智能终端之间互联互通,可就地分享重要信息。通过智能终端的入网配置流程用例,基于所提通信方案的分布式馈线自动化用例,验证了即插即用功能和分布式控制的效果。
The new distribution grid will be heavily connected to distributed energy resources,it will become the main battlefield of constructing new power systems.However,the silo communication architecture of the traditional distribution grid and its 101/104 communication protocol cannot support the D2C and D2D communication requirements of the new distribution grid.It is urgent to improve the information collection and convergence,edge computing,plug and play capabilities for intelligent terminals of the distribution grid,and seek communication solutions that meet the communication requirements of the new distribution grid,to provide the underlying technical framework support for the reliable operation of the new distribution grid.Therefore,this paper proposes an intelligent terminal distributed control communication solution for the new distribution system.First,a more efficient distributed coordinated control architecture allowing distributed intelligent nodes to interact with each other is proposed.Then,IEC 61850 modeling technology is used to model the intelligent terminal,and IEC 62361 standards are followed to solve the problem of the CIM model and IEC 61850 model integration.Finally,a highly reliable and highly real-time Internet of Things communication protocol-DDS is proposed to realize the mapping of the model on the protocol.Through this communication solution,intelligent terminals have the ability to plug and play,and intelligent terminals can communicate with each other and share important information locally,which facilitates the implementation of distributed power coordination and mutual aid strategy.This paper also introduces a use case of the grid access configuration process of the intelligent terminal,and a use case of distributed feeder automation based on this communication solutions to verify the plug and play function and the effect of distributed control.
