| Abstract: | The multi-energy supply in a regional integrated energy system(RIES)can be flexibly adjusted by a hydrogen storage system through the bidirectional conversion between electricity and hydrogen.In this paper,in order to realize an efficient conversion and utilization of various energy sources in the system,the operating characteristics of each part of the hydrogen storage system are analyzed in detail.Combined with the structure of energy flow in the system and the characteristics of cooling and heating load demands,a coupling mode of the fuel cell’s power and heat output with the energy flow in the system and an operation mode of the combined cooling,heating and power system are designed,and the system operation is optimized to achieve economic optimality.The results of an example show that multiple load demands can be satisfied by the fuel cell in the designed operation mode,thereby realizing the cascaded utilization of energy and improving the economy of system operation. |
