摘　　要：原有的电力系统调度模型是物理模型与信息模型分立的。建立信息物理融合的电力系统调度模型,可以充分分析与挖掘可调资源的调节能力,扩大电力系统可调度空间,增强电网对可再生能源的消纳能力。为此以我国现有电力系统调度框架为基础,提出了一种信息物理融合的电力系统日前-日内调度框架,在此框架下对电力系统源-网-荷建模,形成信息物理融合的电力系统日前-日内调度模型。基于所建模型,以经济调度为目标,提出了电力系统日前-日内优化调度策略。算例分析验证了所提策略的有效性,结果表明电力系统的信息物理融合建设可以降低系统的运行成本。最后指出在电力系统的信息物理融合建设过程中应以目标为导向,建设多时间尺度的分层级信息物理融合电力系统。The original power system dispatching model is separated from physical model and information model.Establishing a cyber-physical integrated power system dispatching model can fully analyze and explore the regulation ability of adjustable resources,expand the dispatchable space of power system,and enhance the grid's ability to consume renewable energy.Based on the existing power system dispatching framework in China,a cyberphysical integrated day-ahead and intra-day dispatching framework for the power system was proposed,under which the source-grid-load model of the power system was established to form a cyber-physical integrated day-ahead and intra-day dispatching model for the power system.Based on the proposed model,the optimal day-ahead and intraday dispatching strategy was proposed with the objective of economic dispatching.The effectiveness of the proposed strategy was verified by example analysis,and the results show that the construction of cyber-physical integration in power systems can reduce the operation cost of system.Finally,it was pointed out that the construction of multitimescale hierarchical cyber-physical integrated power system should be goal-oriented in the process of cyberphysical integration construction of power system.
