摘　　要：目前对于综合能源系统的建模,更多从系统输入-输出关系、内部状态与输入输出的关系进行描述,其内部状态在不同阶段的转移过程难以清晰表达。在分布式可再生能源占比大幅度提升后,综合能源系统在不同阶段的运行状态及状态转移过程需要可观可控。为此,提出了基于混合自动机的综合能源系统分阶段状态转移空间建模方法,对综合能源系统内部状态的分阶段转移条件及其转移过程进行精准描述,有利于对综合能源系统内部所有能源生产单元和能源消费单元从启动、运行到停止的全过程进行分阶段管理与优化控制。仿真算例表明,所提模型对综合能源系统分阶段的状态转移轨迹实现了全过程观测,有利于实现全过程分阶段的高效管理与优化控制。At present,the modeling of integrated energy systems(IES)is more described from the input-output relationship of the system and the relationship between internal state and input-output,and the transfer process of its internal state in different stages is difficult to be presented clearly.After the large increase of the proportion of distributed renewable energy,the operating states and state transition processes of IES at different stages need to be observable and controllable.Therefore,a hybrid automata-based phased state transfer space modeling method for IES is proposed,which can accurately describe the transfer conditions of the internal state of the IES and its transfer process,and is conducive to phased management and optimal control of all energy production units and energy consumption units in IES from start-up,operation to stop.The simulation results show that the proposed model achieves the whole process observation for the state transfer trajectory of the IES,which is conducive to the efficient management and optimal control of the whole process in stages.
