摘　　要：综合能源系统(IES)为多种能源的高效协同和互补利用提供了重要平台。源网荷储动态建模技术是IES实现动态多时间尺度仿真和优化计算的重要因素,也是确保IES安全和稳定运行的必要前提。在介绍IES中源网荷储侧主要的动态模型及源荷不确定性模型的基础上,分析了源网荷储动态建模技术在统一建模研究及框架中的运用现状,展望了动态建模的发展方向。源网荷储各类动态模型需要进一步平衡精度和时间复杂度,并引入统一动态建模框架中,最终构建统一仿真平台和数字孪生系统。Integrated energy system(IES)provides an important platform for efficient synergy and complementary utilization of multiple energy sources.The source-grid-load-storage dynamic modeling technology is an important factor for IES to realize dynamic multi-time scale simulation and optimization calculation,and is also a necessary prerequisite to ensure safe and stable operation of the IES.This paper introduces the main dynamic models of source-grid-load-storage side of the IES and uncertainty models of the IES.On this basis,it analyzes the current status of the application of source-grid-load-storage dynamic modeling techniques in the unified modeling research and framework,and outlooks the development direction of dynamic modeling.The result shows that,various types of dynamic models of source,grid,load and storage need to be further balanced in terms of accuracy and time complexity,thus to be further introduced into the unified dynamic modeling framework,and eventually build a unified simulation platform and digital twin system.
