综合能源网络建模与运维技术研究综述OA

Currently,the coupling degree of multiple heterogeneous energy sources is constantly deepening,with a high proportion of clean energy penetration.The integrated energy network couples multiple energy types such as electricity,gas,heat,and cold,achieving coordinated planning and mutual regulation among different energy networks.It is considered one of the important means to promote the consumption of renewable energy and improve energy utilization efficiency.Firstly,starting from the analysis of the characteristics of the integrated energy network,the differential characteristics of its multiple energy flows,the storage characteristics of the natural gas network,and the thermal delay characteristics of the thermal network were mainly analyzed.Then,in the aspect of integrated energy network modeling,three modeling methods were introduced respectively:the mechanism analysis modeling method,the data-driven modeling method,and the unified energy path modeling method.Moreover,in terms of integrated energy network state estimation,the development history and main methods of comprehensive energy network state estimation were summarized,and the current research status of integrated energy network operation reliability evaluation at home and abroad was elaborated.Finally,the outlook of integrated energy network modeling method and state estimation was given,which can provide reference for researchers in this direction.
