Abstract: In order to take full account of interactive hydrogen energy conversion and utilization in the integrated energy microgrid, this paper proposes a coordinated dispatch method of the integrated energy microgrid. First, a typical architecture of the integrated energy microgrid considering hydrogen energy interaction is proposed. Second, the energy efficiency and economic model of key equipment is constructed with hydrogen energy as the core part. Then, the day-ahead dispatch model of the integrated energy microgrid is constructed and solved by taking advantage of the chaos enhanced fireworks optimization algorithm according to the related dispatch properties. Finally, through the comparison and analysis of actual case studies the effectiveness and applicability of the proposed model method are verified.
