大规模用户接入配电网后,新型配电物联网模型更加复杂,因配电网设备繁多、规模庞大,传统的仿真方法和仿真工具无法满足配电物联网的仿真要求.提出了配电物联网典型数字孪生场景、多类型能量流与信息流高度融合、多元化主体行为的动态仿真架构.该架构可支持灵活化网架构建、精细化信息过程描述、信息物理复杂交互下的系统验证等功能.针对含分布式能源接入配电网的典型信息物理交互场景,进行了实例分析,仿真结论验证了该仿真平台的实用性与有效性.
In response to the problem that traditional simulation methods and tools cannot meet the simulation needs of the new distribution internet of things due to its complex model,numerous devices,and large scale,this paper proposes a typical digital twin scenario of the distribution internet of things and a dynamic simulation architecture that highly integrates multiple types of energy and information flows and diversified subject behaviors.This architecture can support functions such as flexible grid construction,refined information process description,and system verification under complex information physical interactions.A specific example analysis was conducted for typical cyber physical interaction scenarios involving distributed energy resources integration into the distribution network,and the simulation results verified the practicality and effectiveness of the proposed simulation platform.
