Abstract

response to the problems that the existing studies have not fully considered the role of hydrogen storage in the longtime and large-scale new energy consumption and the existing energy systems containing hydrogen storage have not fully considered the severe weather conditions in the scheduling, a medium-term and long-term optimal scheduling for community integrated energy system with high proportion of renewable energy and multi-type energy storage is proposed. Firstly, a typical day selection method and a typical day sequence formation method are proposed based on the traditional multi-scenario method and the year-round weather conditions; secondly, a medium-term and long-term operation state description method for hydrogen energy storage considering the internal characteristics of typical days and the external arrangement sequence of typical days is proposed; again, the architecture of the integrated energy system containing hydrogen and thermal energy storage is introduced. Based on the internal characteristics of a typical day and the external linkage of a typical day, a medium-term and long-term optimal scheduling model and solution method for the community integrated energy system with high proportion of renewable energy and multi-type energy storage are proposed. Finally, the effectiveness and practicality of the proposed method are verified through the analysis of calculation cases.
