中文摘要：
多能流是能源互联网的重要特征之一,涵盖电、热、冷、气、交通等多个能流子系统,带来诸多效益的同时也使系统更加复杂,安全问题更加突出。提出了面向能源互联网的多能流静态安全分析的概念和方法。多能流系统需要根据能流子系统之间的耦合程度确定合适的边界,其组成可分为耦合元件和非耦合元件。多能流系统静态模型的共性表现为网络拓扑约束和广义基尔霍夫定律,个性表现为支路特性和耦合元件特性。多能流求解方法可以分为联合求解和解耦求解。给出多能流静态安全分析的安全运行约束、运行状态分类、预想事故集和流程。电-热耦合算例验证不同能流子系统之间的相互影响,说明开展多能流静态安全分析的必要性。
英文摘要：
Multi-energy flow（MEF） is a key feature of energy internet, covering various subsystems such as power, heating, cooling, gas, transportation, etc. It brings many benefits but also complicates system, especially its security problem. This paper proposes a concept and method of static security analysis of multi-energy flow for energy internet. MEF system, consisting of coupling and non-coupling components, is dependent on coupling between subsystems. Common static models of different subsystems include network topology constraints and generalized Kirchhoff＇s law, while their differences are shown in branch characteristics and coupling components. Multi-energy flowcalculation includes integrated and decomposed methods. This paper develops security operation constraints, operating states, contingency set and process of MEF static security analysis. A power-heating combined case study verified interactions between different subsystems, showing necessity of MEF static security analysis.
