多场景通用的综合能源系统标准化信息模型与应用

Universal Standardized Information Model of Integrated Energy System for Multiple Scenarios and Its Application

标准化是实现综合能源系统多管理主体信息交互的必要途径。与传统电力系统相比,综合能源系统标准化存在多能流耦合、运行场景更加复杂、设备种类繁多且特性各异等技术挑战。借鉴电力系统标准化的经验,设计了“单质能流层-多能耦合层”两层综合能源系统模型架构,以适应不同的运行场景;提出了类电力系统的异质能流标准化建模方法,实现了单质能流的源网荷结构化建模;提出了基于聚合-派生的多能流耦合设备标准化建模方法,兼顾了各种能量耦合设备的共性和个性特征;研发的标准化模型生成模块已集成到园区综合能源管理系统,并在中国某北方园区在线使用,实现了冷热电气多能流系统模型的标准化表达与信息交互。

Standardization is a necessary way to realize information interaction among multiple management entities of the integrated energy system(IES).Compared with traditional power systems,the standardization of IES has technical challenges such as multi-energy flow coupling,more complex operation scenarios,and various types of equipment with different characteristics.Based on the experience of power system standardization,a two-layer IES model architecture with single-energy-flow layer and multi-energy coupling layer is designed to adapt to different operaton senarios.A standardized modeling method for heterogeneous energy flow of quasi-power system is proposed and the structured modeling of source-grid-load of single-energy-flow is realized.A standardized modeling method for multi-energy coupling equipment based on aggregation-derivation is proposed,which takes into account the common and individual characteristics of various energy coupling equipment.The developed standardized model generation module has been integrated into a park integrated energy management system and used online in a northern park in China,realizing standardized expression and information interaction of the coolly-heat-electricity-gas multi-energy system model.
