【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。
[Abstract]:Multi-energy flow is one of the important characteristics of the energy Internet. It covers many energy flow subsystems, such as electricity, heat, cold, gas, transportation and so on. It brings many benefits and makes the system more complex. The concept and method of multi-energy flow static security analysis for energy Internet are put forward. The multi-energy flow system needs to determine the appropriate boundary according to the coupling degree between the energy flow subsystems. Its composition can be divided into coupling elements and uncoupled elements. The common features of the static model of multi-energy flow system are network topology constraints and generalized Kirchhoff's law. The solution method of multi-energy flow can be divided into joint solution and decoupling solution. The safe operation constraints and operation state classification of multi-energy flow static security analysis are given. An electric-thermal coupling example is used to verify the interaction between different energy flow subsystems, which indicates the necessity of static safety analysis of multi-energy flow.
