摘　　要：多能流潮流分析是研究综合能源系统(IES)状态估计、安全分析与优化控制的重要基础工作。为方便以潮流分析方法研究电、气、热(冷)等能源间的相互转化与耦合联供,综合分析了IES潮流分析的2个主要研究方向,其一为在某确定工况下根据已知参数计算系统的运行状态,包括稳态和动态潮流;其二为在前者基础上考虑系统不确定性参数对系统运行影响的不确定性潮流,并主要以概率潮流解法进行讨论,指出目前多能流混合潮流的研究进展与解耦方法与局限性,总结了最优潮流的求解方式和应用现状。结果表明,目前多能流稳态计算已较为成熟;动态潮流模型多以差分法求解,但准确度和求解效率仍有待提高;不确定性潮流对数据要求较高,无法兼顾计算精度和效率;最优潮流研究多集中于单一目标优化,较少涉及多目标并考虑不确定因素约束的复杂模型。最后,提出目前混合能源潮流计算在模型约束和算法难度等方面的局限性与未来发展前景。Multi-energy flow analysis is a crucial and fundamental link for the state estimation,security analysis and optimal regulation of an integrated energy system(IES).To study the mutual conversion and coupling of electric power,gas,thermal power and cold energy with power flow analysis,two main research directions of integrated energy system power flow analysis are compared.The first one is to calculate the system's operating state,including steady-state and dynamic power flow,based on known parameters under a certain operating condition.On this basis,the second one considers the impact of uncertain parameters on system operation,and study the uncertain power flow through probabilistic power flow analysis.The research progress made in multi-energy hybrid flow and limitations of current decoupling methods are pointed out,and the optimal power flow solution and its applications are summarized.The results show that the multi-energy steadystate flow calculation is relatively mature,but the dynamic power flow model mostly solved by the differential method lacks accuracy and solution efficiency.Uncertainty power flow requires highly on data and cannot balance computing accuracy and efficiency.The optimal power flow model mainly focuses on single-objective optimization,while seldom considers multiple objectives or uncertain factors.Finally,the limitations of hybrid energy power flow calculation in terms of its model constraints and algorithm complexity are proposed,and its prospects are made.
