针对SOFC分布式能源系统中跨时间尺度的电热动态特性研究方面的不足以及可再生能源渗透带来的系统灵活性和稳定性问题，提出了一种基于固体氧化物燃料电池（SOFC）的分布式能源系统，在对SOFC跨时间尺度电热的动态特性分析的基础上，创新性地设计一种SOFC辅助电力调峰的系统调控策略。基于Simulink仿真平台，探究了分布式能源系统在不同时间尺度负荷波动下的电热动态响应和协同运行特性。结果表明，热维持显著降低了SOFC的热惯性，提高SOFC的调峰能力和稳定性，且所设计的调控策略能够在保障系统安全运行的同时响应系统的电热需求，为相关分布式能源系统的调控和稳定运行提供了理论依据。

To address the challenges of cross-timescale electrothermal dynamics characteristics and the flexibility and stability issues caused by high renewable energy penetration in SOFC-based distributed energy systems, a distributed energy system using solid oxide fuel cells (SOFCs) is proposed. Based on the analysis of SOFC electrothermal dynamics characteristics across different timescales, an innovative SOFC-assisted peak shaving control strategy is designed.  Using the Simulink simulation platform, the electrothermal dynamic response and coordinated operation under varying load fluctuations are explored. Results indicate that thermal maintenance effectively reduces SOFC thermal inertia, enhancing peak shaving capability and stability. The control strategy ensures safe operation while meeting electrothermal demands, providing a theoretical basis for regulating and stabilizing SOFC-based distributed energy systems.
