摘要:
综合能源系统为提高能源利用效率、多能互补及构建低碳可持续能源系统奠定了基础,然而值得注意的是,深度耦合的多能源系统亦面临着不可忽视的运行风险,尤其当耦合系统之间缺乏有效的协同安全控制策略。鉴于此,综述了电-气互联综合能源系统安全分析与优化控制研究,介绍了电-气互联综合能源系统稳态与暂态潮流模型,包括非线性、线性及凸松弛模型;介绍了电-气互联综合能源系统安全分析研究,包括状态估计、安全评估、可靠性分析及韧性分析;介绍了电-气互联综合能源系统优化控制研究,提出了多时段滚动预防与校正控制模型;展望了电-气互联综合能源系统安全分析与优化控制未来可深入研究的方向。

Abstract:
Integrated energy system positively contributes to the improved energy utilization efficiency, multi-energy complement, and the construction of a low-carbon sustainable energy system. However, it is notable that the deep interdependency among multiple energy systems creates significant operational risks. As such, the research on security analysis and optimal control of electricity-gas integrated energy system is reviewed. The steady-state and transient energy flow models of electricity-gas integrated energy system are introduced, which includes the exact nonlinear, linear, and convex models. Then, the security analysis of electricity-gas integrated energy system is introduced, in which the state estimation, security assessment, reliability analysis, and resilience analysis are discussed. Subsequently, the optimal control model of electricity-gas integrated energy system is introduced, in which the multi-period optimal preventive and corrective models are proposed. Finally, the promising research directions on security analysis and optimal control of electricity-gas integrated energy system are summarized.
Key words:  electricity-gas integrated energy system  operational risk  steady-state energy flow model  transient energy flow model  security analysis  optimal control
