【摘要】：多能流是能源互聯(lián)網(wǎng)的重要特征之一,涵蓋電、熱、冷、氣、交通等多個能流子系統(tǒng),帶來諸多效益的同時也使系統(tǒng)更加復(fù)雜,安全問題更加突出。提出了面向能源互聯(lián)網(wǎng)的多能流靜態(tài)安全分析的概念和方法。多能流系統(tǒng)需要根據(jù)能流子系統(tǒng)之間的耦合程度確定合適的邊界,其組成可分為耦合元件和非耦合元件。多能流系統(tǒng)靜態(tài)模型的共性表現(xiàn)為網(wǎng)絡(luò)拓?fù)浼s束和廣義基爾霍夫定律,個性表現(xiàn)為支路特性和耦合元件特性。多能流求解方法可以分為聯(lián)合求解和解耦求解。給出多能流靜態(tài)安全分析的安全運行約束、運行狀態(tài)分類、預(yù)想事故集和流程。電-熱耦合算例驗證不同能流子系統(tǒng)之間的相互影響,說明開展多能流靜態(tài)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.
