摘　　要：多源配电网有较强的随机性特征和时变特性,需要研究基于信息物理融合的多源配电网动态潮流网损分析方法,用于深入揭示电网运行的复杂内在特性。该方法需综合考虑分布式电源随机注入功率和场景变化,同时有效支撑分布式电源对非可控能源与负荷的调节作用,以获得系统在所研究的连续时间段内的确定性网损分析和运行轨迹。建立连续变量和离散状态相融合的可控分布式能源混合逻辑动态模型及配电网动态潮流模型,揭示在不确定性背景和信息与物理交互作用下电网运行的复杂内在特性,实现基于配电网动态潮流模型的多源异构配电网网络损耗计算。Multi-source distribution network has strong stochastic and time-varying characteristics.It is necessary to study the dynamic power flow loss analysis method based on Information Physics fusion for revealing the complex inherent characteristics of power grid operation.In order to obtain deterministic loss analysis and operation trajectory of the system in the continuous period under study,this method needs to take into account the random injection power and scenario changes of the distributed generation,and effectively support the regulating effect of the distributed generation on uncontrollable energy and load.The mixed logic dynamic model of controllable distributed energy and the dynamic power flow model of distribution network based on the integration of continuous variables and discrete states are established.The complex inherent characteristics of power grid operation under the interaction of uncertain background and information and physics are revealed.The loss meter of multi-source heterogeneous distribution network based on the dynamic power flow model of distribution network is realized.
