Review on Reliability Evaluation of Urban Integrated Energy System based on Multi-Source Data

UIES (UIES) refers to the integrated energy system in which the main energy components are distributed in the city. In UIES, because of the coupling of many subsystems, such as power, heat, air conditioning, transportation, natural gas and communication system, in order to maintain stable production and operation, urban energy system must collect complex and multi-sources of data. In addition, the coupling characteristics between energy subsystems also bring difficulty to UIES. In this paper, the coupling model of UIES composed of different energy subsystems is studied, then the multi-source data composition of UIES is analyzed, and then the reliability evaluation of individual energy subsystem is discussed. Finally, taking the power-natural gas coupling system as an example, the types of multi-source data to be considered in the reliability evaluation of integrated energy system are analyzed. Through the review and analysis of the latest literature, it is expected to provide a reference for the reliability evaluation of UIES.
