In order to deal with the difficulty of new energy consumption and the lack of system regulation and control capacity in the process of new power system construction,this paper proposes a low-carbon economic dispatching strategy of source-load-storage considering the coordinated operation of a carbon capture unit and a hydrogen energy storage system.Firstly,the operation mechanism of the three sides of source-load-storage is analyzed,and the flexibility of power system scheduling is improved by making full use of the carbon capture units,the hydrogen energy storage systems and the demand response.Secondly,the structure framework of source-grid-load coordinated operation is constructed,and the coordinated operation characteristics of a carbon capture unit and a hydrogen energy storage system are studied in view of the shortcomings in the operation of the carbon capture unit and the hydrogen energy storage system under the demands of the spinning reserve.Finally,aiming at the optimal comprehensive cost of the system,a low-carbon economic dispatching model of source-load-storage coordinated operation of carbon capture units and hydrogen energy storage systems is established.The fuzzy membership function is used to describe the system uncertainty and determine the system spinning reserve demands.The example verification shows that the model proposed in this paper is able to significantly improve the new energy consumption level of the system under the premise of taking into account the economy and low carbon of the system operation.
