高温超导储能系统建模及故障特性分析
Modeling and Fault Characteristic Analysis for High-temperature Superconducting Magnetic Energy Storage System
摘要
Abstract
The instability of renewable energy power generation has exerted a significant impact on the safe and stable operation of new power systems,and the energy storage technology serves as an effective solution to address this issue.Owing to its advantages such as high power density and fast response speed,the high-temperature superconducting magnetic energy storage(HTS-SMES)demonstrates promising application potential in mitigating power fluctuations of renewable energy sources and enhancing power quality.To comprehensively and thoroughly analyze the fault characteristics of HTS-SMES after grid integration,this paper establishes a simulation model of the HTS-SMES grid-connected system based on its topological structure and control strategy.The model simulates the dynamic response processes following an AC-side short-circuit fault and a DC-side magnet quench fault on the HTS-SMES side in both charging and discharging scenarios.On this basis,the differences in fault characteristics of HTS-SMES in charging and discharging scenarios are clarified,and the primary reasons for these differences are analyzed.Finally,the functionality of the established model is validated using PSCAD/EMTDC.关键词
